Description

BLOC OPTIQUE DE VÉHICULE À MASQUE À CELLULE PHOTOVOLTAÏQUE ALIMENTANT DES MOYENS DE CHAUFFAGE DE LA GLACE  PHOTOVOLTAIC CELL MASK VEHICLE OPTICAL BLOCK SUPPORTING MEANS FOR ICE HEATING
L'invention concerne les blocs optiques de véhicule qui sont équipés de moyens de chauffage destinés à chauffer leur glace. The invention relates to vehicle optical units which are equipped with heating means for heating their ice.
Certains blocs optiques de véhicule comprennent au moins une source propre à générer des photons destinés à participer à une fonction photométrique (d'éclairage ou de signalisation) et au moins une lentille propre à défléchir les photons générés afin qu'ils se dirigent vers une glace assurant l'interface avec l'extérieur. Lorsque certaines conditions météorologiques sont présentes à l'extérieur du véhicule, de la condensation, voire de la glace, peut se former sur la face interne et/ou la face externe de la glace, ce qui dégrade la fonction photométrique et accessoirement nuit à l'impression visuelle de qualité du véhicule. Some vehicle optical blocks comprise at least one source capable of generating photons intended to participate in a photometric function (lighting or signaling) and at least one lens capable of deflecting the generated photons so that they are directed towards an ice-cream providing the interface with the outside. When certain weather conditions are present outside the vehicle, condensation, or even ice, may form on the inner face and / or the outer face of the ice, which degrades the photometric function and incidentally damages the weather. visual impression of vehicle quality.
Ce phénomène peut être légèrement réduit lorsque la source qui participe à la fonction photométrique génère une partie de ses photons dans le domaine de l'infrarouge. Mais certaines sources, comme par exemple les diodes électroluminescentes (ou LEDs), ne produisent quasiment pas de photons dans l'infrarouge. This phenomenon can be slightly reduced when the source participating in the photometric function generates a portion of its photons in the infrared range. But some sources, such as light-emitting diodes (or LEDs), produce almost no photons in the infrared.
Afin d'empêcher le phénomène précité, il est possible d'installer dans le bloc optique des moyens de chauffage destinés à chauffer sa glace. Ces moyens de chauffage sont alimentés en courant électrique par le réseau d'alimentation électrique du véhicule via des câbles électriques, ce qui induit une consommation de l'énergie disponible dans le véhicule et donc peut réduire son autonomie. In order to prevent the aforementioned phenomenon, it is possible to install in the optical block heating means for heating its ice. These heating means are supplied with electric current by the vehicle power supply network via electric cables, which induces a consumption of the available energy in the vehicle and therefore can reduce its autonomy.
L'invention a notamment pour but d'améliorer la situation.  The purpose of the invention is in particular to improve the situation.
Elle propose notamment à cet effet un bloc optique destiné à équiper un véhicule et comprenant une glace, des moyens de chauffage propres à produire des calories destinées à réchauffer la glace, au moins une source propre à générer des photons destinés à participer à une fonction photométrique, au moins une lentille propre à défléchir les photons générés afin qu'ils se dirigent vers la glace, et au moins un masque comportant une face propre à renvoyer des photons incidents ne se dirigeant pas vers la glace. It proposes for this purpose an optical unit intended to equip a vehicle and comprising an ice, heating means capable of producing calories for heating the ice, at least one source capable of generating photons intended to participate in a photometric function, at least one lens capable of deflecting the generated photons so that they are directed towards the ice, and at least one mask having a clean face to return incident photons not heading not towards the ice.
Ce bloc optique se caractérise par le fait que son masque comprend sur sa face de renvoi au moins une cellule photovoltaïque qui est agencée pour convertir des photons incidents reçus en un courant électrique propre à alimenter les moyens de chauffage pour qu'ils produisent des calories propres à réchauffer la glace.  This optical unit is characterized in that its mask comprises on its return face at least one photovoltaic cell which is arranged to convert incident photons received into a clean electric current to supply the heating means so that they produce clean calories to warm the ice.
On obtient ainsi un bloc optique muni de moyens de chauffage avantageusement alimentés en courant électrique par au moins une cellule photovoltaïque, ce qui s'avère économique.  An optical unit is thus obtained provided with heating means advantageously supplied with electric current by at least one photovoltaic cell, which proves to be economical.
Le bloc optique selon l'invention peut comporter d'autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :  The optical block according to the invention may comprise other characteristics that can be taken separately or in combination, and in particular:
- ses moyens de chauffage peuvent être de type résistif et plats ;  - Its heating means can be resistive type and flat;
- dans un premier mode de réalisation ses moyens de chauffage peuvent être installés sur une partie d'une face interne de la glace ;  in a first embodiment, its heating means can be installed on part of an inner face of the ice;
ses moyens de chauffage peuvent être installés sur une partie périphérique de la face interne de la glace ;  its heating means can be installed on a peripheral portion of the inner face of the ice;
- dans un second mode de réalisation ses moyens de chauffage peuvent être installés sur une partie d'une face arrière d'une pièce comprenant la source, la face arrière étant opposée à une face avant d'où partent les photons générés par la source ;  in a second embodiment, its heating means may be installed on a part of a rear face of a part comprising the source, the rear face being opposed to a front face from which the photons generated by the source depart;
- il peut comprendre au moins un dispositif d'éclairage, d'une part, comportant la source et la lentille, et, d'autre part, monté à rotation autour d'au moins une première direction prédéfinie ;  it may comprise at least one lighting device, on the one hand, comprising the source and the lens, and, on the other hand, rotatably mounted around at least a first predefined direction;
chaque pièce peut être propre à être entraînée en rotation autour de la première direction prédéfinie.  each piece may be able to be rotated around the first predefined direction.
• chaque pièce peut être propre à être entraînée en rotation autour d'une seconde direction prédéfinie perpendiculaire à la première direction prédéfinie. Dans ce cas la lentille peut être couplée en rotation à la pièce associée ; Each piece can be adapted to be rotated about a second predefined direction perpendicular to the first predefined direction. In this case the lens can be coupled in rotation to the associated part;
- chaque source peut comprendre au moins une diode électroluminescente.  each source may comprise at least one light emitting diode.
L'invention propose également un véhicule, éventuellement de type automobile, et comprenant au moins un bloc optique du type de celui présenté ci-avant.  The invention also proposes a vehicle, possibly of automobile type, and comprising at least one optical block of the type of that presented above.
D'autres caractéristiques et avantages de l'invention apparaîtront à l'examen de la description détaillée ci-après, et des dessins annexés, sur lesquels :  Other features and advantages of the invention will appear on examining the detailed description below, and the attached drawings, in which:
- la figure 1 illustre de façon schématique et fonctionnelle, dans une vue en coupe longitudinale, un exemple de réalisation d'un bloc optique selon l'invention, et  FIG. 1 schematically and functionally illustrates, in a longitudinal sectional view, an exemplary embodiment of an optical block according to the invention, and
- la figure 2 illustre de façon schématique, dans une vue en perspective, une variante de réalisation d'un dispositif d'éclairage destiné à équiper un bloc optique selon l'invention.  - Figure 2 schematically illustrates, in a perspective view, an alternative embodiment of a lighting device for equipping an optical unit according to the invention.
L'invention a notamment pour but de proposer un bloc optique BO destiné à équiper un véhicule et pourvu de moyens de chauffage MC.  The object of the invention is notably to propose an optical block BO intended to equip a vehicle and provided with heating means MC.
Dans ce qui suit, on considère, à titre d'exemple non limitatif, que le bloc optique BO est destiné à équiper un véhicule automobile. Mais l'invention n'est pas limitée à ce type de véhicule. Elle concerne en effet tout type de véhicule équipé d'au moins un bloc optique comprenant un dispositif d'éclairage et une glace comportant des faces interne et externe sur l'une au moins desquelles peut se former de la condensation ou de la glace.  In the following, it is considered, by way of non-limiting example, that the optical block BO is intended to equip a motor vehicle. But the invention is not limited to this type of vehicle. It concerns any type of vehicle equipped with at least one optical unit comprising a lighting device and an ice having inner and outer faces on at least one of which may form condensation or ice.
On entend ici par « dispositif d'éclairage » un dispositif lumineux destiné à participer à au moins une fonction photométrique d'éclairage ou de signalisation.  Here, the term "lighting device" means a light device intended to participate in at least one photometric lighting or signaling function.
Par ailleurs, on considère dans ce qui suit, à titre d'exemple non limitatif, que le bloc optique BO est un phare (ou projecteur avant). Mais l'invention n'est pas limitée à ce type de bloc optique. Elle concerne en effet également les feux avant de signalisation et les feux arrière.  Furthermore, it is considered in the following, by way of non-limiting example, the optical block BO is a headlight (or front projector). But the invention is not limited to this type of optical block. It also concerns the front lights and rear lights.
On a schématiquement illustré sur la figure 1 un exemple de réalisation simplifié d'un bloc optique BO selon l'invention (ici un phare à titre d'exemple non limitatif). FIG. 1 schematically illustrates a simplified embodiment of an optical block BO according to the invention (here a lighthouse for non-limiting example).
Comme illustré, un bloc optique BO, selon l'invention, comprend, d'une part, un espace interne El, délimité notamment par une glace G et dans lequel sont installés au moins une source de lumière SL, au moins une lentille L et au moins un masque M, et, d'autre part, des moyens de chauffage MC.  As illustrated, an optical block BO, according to the invention, comprises, on the one hand, an internal space El delimited in particular by an ice-cream G and in which at least one light source SL is installed, at least one lens L and at least one mask M, and, secondly, heating means MC.
Dans l'exemple non limitatif illustré sur la figure 1 , l'espace interne El du bloc optique BO ne comprend qu'une source de lumière SL associée à une lentille L et à un masque M. Le bloc optique BO ne comprend donc qu'un seul dispositif d'éclairage DE comportant notamment la source de lumière SL et la lentille L. Mais le bloc optique BO pourrait comporter plusieurs (au moins deux) dispositifs d'éclairage DE, éventuellement associés à plusieurs (au moins deux) masques M.  In the nonlimiting example illustrated in FIG. 1, the internal space E1 of the optical block BO comprises only a light source SL associated with a lens L and a mask M. The optical unit BO therefore comprises only a single lighting device DE comprising in particular the light source SL and the lens L. But the optical block BO could comprise several (at least two) lighting devices DE, possibly associated with several (at least two) masks M.
La glace G est solidarisée fixement (par exemple par collage) et de façon étanche à un boîtier. Elle peut être réalisée en matière plastique (ou synthétique) transparente ou bien en verre.  The ice G is fixedly secured (for example by gluing) and sealed to a housing. It can be made of transparent plastic or synthetic material or glass.
Les moyens de chauffage MC sont agencés de manière à produire des calories qui sont destinées à réchauffer la glace G, lorsqu'ils sont alimentés en courant électrique.  The heating means MC are arranged to produce calories which are intended to heat the ice G, when they are supplied with electric current.
Chaque (la) source de lumière SL est propre à générer des photons qui sont destinés à participer à une fonction photométrique (d'éclairage ou de signalisation).  Each (the) light source SL is able to generate photons that are intended to participate in a photometric function (lighting or signaling).
Par exemple, la (chaque) source de lumière SL peut comporter au moins une diode électroluminescente (ou LED). En variante, elle peut comporter au moins une diode laser ou un laser à gaz ou encore une lampe (ou ampoule).  For example, the (each) light source SL may comprise at least one light emitting diode (or LED). Alternatively, it may comprise at least one laser diode or a gas laser or a lamp (or bulb).
Chaque (la) lentille L est agencée de manière à défléchir les photons générés par la source SL associée afin qu'ils se dirigent vers la glace G (flèche F1 ). On notera que la lentille L peut éventuellement défléchir les photons générés afin qu'ils se dirigent vers la glace G après avoir été renvoyés par un réflecteur. Dans ce cas, le dispositif d'éclairage DE comprend également un tel réflecteur. Dans une variante de réalisation, le réflecteur pourrait être intercalé entre la source SL et la lentille L, plutôt que placé en aval de la lentille L. Chaque (le) masque M comporte une face FM dite de renvoi du fait qu'elle est propre à renvoyer des photons incidents qui ne se dirigent pas directement vers la glace G. Cette face de renvoi FM est par exemple aluminée. Each (the) lens L is arranged to deflect the photons generated by the associated source SL so that they move towards the ice G (arrow F1). Note that the lens L may optionally deflect the photons generated so that they go to the ice G after being returned by a reflector. In this case, the lighting device DE also comprises such a reflector. In an alternative embodiment, the reflector could be interposed between the source SL and the lens L, rather than placed downstream of the lens L. Each (the) mask M includes a so-called FM face of return because it is adapted to return incident photons that do not go directly to the ice G. This deflection face FM is for example aluminized.
On notera que dans l'exemple non limitatif illustré sur la figure 1 , le masque M est placé en dessous du niveau du dispositif d'éclairage DE afin de renvoyer les photons vers le haut. Dans un mode de réalisation inversé, le masque M peut être placé au-dessus du niveau du dispositif d'éclairage DE afin de renvoyer les photons vers le bas. Mais le masque M peut également entourer partiellement ou totalement le dispositif d'éclairage DE.  Note that in the non-limiting example illustrated in Figure 1, the mask M is placed below the level of the lighting device DE to return the photons upwards. In an inverted embodiment, the mask M may be placed above the level of the lighting device DE in order to return the photons downwards. But the mask M can also partially or completely surround the lighting device DE.
A titre d'exemple non limitatif, la fonction photométrique assurée par le dispositif d'éclairage DE est destinée à l'éclairage extérieur. Par conséquent, il pourra notamment s'agir d'une fonction de feu de croisement (ou code), d'une fonction de feu antibrouillard, ou d'une fonction de feu de route. Mais la fonction photométrique assurée par le dispositif d'éclairage DE pourrait être destinée à la signalisation.  By way of non-limiting example, the photometric function provided by the lighting device DE is intended for external lighting. Therefore, it may include a function of dipped beam (or code), a fog lamp function, or a high beam function. But the photometric function provided by the lighting device DE could be intended for signaling.
La face de renvoi FM du masque M comprend au moins une cellule photovoltaïque CP agencée pour convertir des photons incidents qu'elle reçoit (flèche F2) en un courant électrique qui est propre à alimenter les moyens de chauffage MC pour qu'ils produisent des calories propres à réchauffer la glace G.  The deflection face FM of the mask M comprises at least one photovoltaic cell CP arranged to convert incident photons it receives (arrow F2) into an electric current which is able to supply the heating means MC to produce calories. suitable for heating ice G.
On notera que ces photons incidents peuvent provenir aussi bien de la lentille L (car une partie des photons générés n'est pas suffisamment défléchie vers la glace G), que de l'extérieur du véhicule (il s'agit alors de photons solaires, par exemple). De ce fait, la cellule photovoltaïque CP peut produire du courant électrique aussi bien lorsque la source SL est en fonctionnement, que lorsque la source SL ne fonctionne pas. Bien entendu dans ce dernier cas l'intensité du courant électrique produit est moindre. It will be noted that these incident photons can come as well from the lens L (because a part of the photons generated is not sufficiently deflected towards the ice-cream G), than from the outside of the vehicle (it is then a matter of solar photons, for example). As a result, the photovoltaic cell CP can produce electric power both when the source SL is in operation and when the source SL does not operate. Of course in the latter case the intensity of the electric current produced is less.
On notera que les moyens de chauffage MC sont de préférence (mais non limitativement) de type résistif et plats. A titre d'exemple, il peut s'agir de pistes résistives du type de celles qui sont fréquemment solidarisées aux lunettes arrière de véhicule pour les désembuer par réchauffement. Dans l'exemple non limitatif illustré sur la figure 1 , les moyens de chauffage MC sont installés sur une partie d'une face interne FI de la glace G, par exemple par collage ou sérigraphie, voire par intégration dans des microcanaux ou nervures. Plus précisément, dans cet exemple les moyens de chauffage MC sont installés sur une partie périphérique PP de la face interne FI de la glace G, afin de ne pas réduire les performances de chaque fonction photométrique assurée par le bloc optique BO. Mais, lorsqu'une partie prédéfinie de la glace G ne sert pas à laisser passer les photons participant à une fonction photométrique, les moyens de chauffage MC peuvent être installés sur cette partie prédéfinie. It will be noted that the heating means MC are preferably (but not exclusively) of the resistive and flat type. For example, it may be resistive tracks of the type that are frequently secured to the rear vehicle glasses to demist by heating. In the nonlimiting example illustrated in FIG. 1, the heating means MC are installed on part of an internal face FI of the ice-cream G, for example by gluing or screen printing, or even by integration in microchannels or ribs. More specifically, in this example the heating means MC are installed on a peripheral portion PP of the inner face FI of the glass G, in order not to reduce the performance of each photometric function provided by the optical block BO. But when a predefined part of the lens G is not used to let the photons participating in a photometric function, the heating means MC can be installed on this predefined part.
Dans un autre exemple non limitatif illustré sur la figure 2, les moyens de chauffage MC peuvent être installés sur une partie d'une face arrière FR d'une pièce PS qui comprend la source SL. Cette face arrière FR est opposée à une face avant d'où partent les photons qui sont générés par la source SL. In another nonlimiting example illustrated in FIG. 2, the heating means MC may be installed on part of a rear face FR of a part PS which comprises the source SL. This rear face FR is opposite a front face from which the photons that are generated by the source SL start.
On notera que dans cet autre exemple, la source SL et la lentille L font partie d'un dispositif d'éclairage DE qui est monté à rotation autour d'au moins une première direction prédéfinie A1 . Par exemple, et comme illustré non limitativement, la pièce PS (qui comprend la source SL) est également propre à être entraînée en rotation autour de la première direction prédéfinie A1 . Cette première direction est par exemple sensiblement verticale de manière à permettre le placement de la face arrière FR de la pièce PS en regard de la glace G, pour rapprocher autant que possible les moyens de chauffage MC de la glace G et ainsi optimiser son chauffage, soit en regard du fond du boîtier du bloc optique BO (à l'opposé de la glace G) pour que la lentille L soit placée en regard de la glace G afin que la fonction photométrique soit assurée. Note that in this other example, the source SL and the lens L are part of a lighting device DE which is rotatably mounted around at least a first predefined direction A1. For example, and as illustrated without limitation, the part PS (which includes the source SL) is also adapted to be rotated around the first predefined direction A1. This first direction is for example substantially vertical so as to allow the placement of the rear face FR of the piece PS opposite the ice G, to bring as close as possible the heating means MC of the ice G and thus optimize its heating, or facing the bottom of the housing of the optical block BO (opposite to the ice G) so that the lens L is placed opposite the glass G so that the photometric function is ensured.
On notera également que dans cet autre exemple non limitatif illustré sur la figure 2, la pièce PS est propre à être entraînée en rotation autour d'une seconde direction prédéfinie A2 qui est perpendiculaire à la première direction prédéfinie A1 . Note also that in this other non-limiting example illustrated in Figure 2, the workpiece PS is adapted to be rotated about a second predefined direction A2 which is perpendicular to the first predefined direction A1.
Plus précisément, la lentille L est solidaire d'une monture ML faisant partie d'un équipage ER solidarisé à une armature AS montée à rotation autour d'un premier axe parallèle à la première direction prédéfinie A1 (et ci- après assimilé à cette dernière). La lentille L est réalisée dans une matière transparente. Il s'agit de préférence d'une matière plastique synthétique, par exemple un polyacrylate, qui offre l'avantage d'offrir de bonnes propriétés optiques (notamment une bonne transparence) et mécaniques (notamment une bonne rigidité). More specifically, the lens L is integral with an ML mount forming part of an ER crew secured to an AS frame rotatably mounted. around a first axis parallel to the first predefined direction A1 (and hereinafter assimilated to the latter). The lens L is made of a transparent material. It is preferably a synthetic plastic material, for example a polyacrylate, which has the advantage of offering good optical properties (including good transparency) and mechanical properties (including good rigidity).
La lentille L présente un dioptre avant (en l'espèce convexe) qui définit un axe optique primaire 01 , et un dioptre arrière (en l'espèce concave) opposé. Le dioptre avant et le dioptre arrière sont reliés par une tranche qui forme un dioptre latéral définissant un axe optique secondaire 02. Dans l'exemple illustré, le contour de la lentille L est sensiblement rectangulaire, mais cette forme est donnée à titre seulement illustratif. The lens L has a front diopter (in this case convex) which defines a primary optical axis 01, and a rear diopter (in this case concave) opposite. The front diopter and the rear diopter are connected by a slice which forms a lateral diopter defining a secondary optical axis O2. In the example illustrated, the contour of the lens L is substantially rectangular, but this shape is given for illustrative purposes only.
Selon un mode de réalisation préféré, les dioptres avant et arrière sont agencés de sorte que l'axe optique primaire 01 et l'axe optique secondaire 02 soient perpendiculaires et s'étendent conjointement dans un plan vertical contenant également le premier axe de rotation A1 . According to a preferred embodiment, the front and rear diopters are arranged so that the primary optical axis 01 and the secondary optical axis O2 are perpendicular and extend jointly in a vertical plane also containing the first axis of rotation A1.
La monture ML est de préférence métallique, et comprend deux branches latérales (qui, comme dans l'exemple illustré, peuvent être coudées), reliées par une barre transversale dans laquelle est ancrée la lentille L. The mount ML is preferably metallic, and comprises two lateral branches (which, as in the example shown, can be bent), connected by a transverse bar in which is anchored the lens L.
Par ses branches, la monture ML est montée à rotation par rapport à l'armature AS autour d'un deuxième axe parallèle à la deuxième direction prédéfinie A2 (et ci-après assimilé à cette dernière). Ce deuxième axe A2 est par exemple formé par des pivots (non représentés) reliant les branches aux bras de l'armature AS, à une extrémité de ceux-ci. De même, le deuxième axe A2 s'étend à une extrémité des branches opposée à la barre transversale. By its branches, the mount ML is rotatably mounted relative to the armature AS about a second axis parallel to the second predefined direction A2 (and hereinafter assimilated thereto). This second axis A2 is for example formed by pivots (not shown) connecting the branches to the arms of the armature AS at one end thereof. Similarly, the second axis A2 extends to one end of the branches opposite to the crossbar.
L'équipage ER comprend la pièce PS comportant la source SL. Cette pièce PS comprend également un réflecteur RL définissant une face avant concave réfléchissante en regard de laquelle la source SL est placée pour l'alimenter en photons d'éclairage, et une face arrière FR convexe opposée, les faces avant et arrière FR étant reliées par une tranche. Le caractère réfléchissant de la face avant est par exemple procuré par un revêtement argenté. The ER crew includes the PS part containing the source SL. This part PS also comprises a reflector RL defining a concave front reflective face opposite which the source SL is placed to supply it with photons of illumination, and an opposite rear face FR convex, the front and rear faces FR being connected by a slice. The character reflective of the front face is for example procured by a silver coating.
Par ailleurs, la lentille L est ici couplée en rotation à la pièce PS, afin de la suivre dans ses déplacements. Moreover, the lens L is here rotatably coupled to the piece PS, in order to follow it in its movements.
On notera que le dispositif d'éclairage DE illustré sur la figure 2 peut être éventuellement installé dans un bloc optique BO dont la glace G est également munie de moyens de chauffage MC complémentaires. It will be noted that the lighting device DE illustrated in FIG. 2 may optionally be installed in an optical block BO whose ice-cream G is also provided with complementary heating means MC.
Quel que soit le mode de réalisation considéré du bloc optique BO, lorsque le courant électrique qui est produit par la (les) cellule(s) photovoltaïque(s) CP n'est pas suffisant pour faire fonctionner correctement les moyens de chauffage MC (et/ou les moyens de chauffage MC complémentaires), c'est le réseau d'alimentation électrique RE du véhicule qui se charge de fournir le courant électrique complémentaire. Whatever the embodiment considered of the optical block BO, when the electric current that is produced by the photovoltaic cell (s) CP (s) is not sufficient to operate properly the heating means MC (and / or the complementary heating means MC), it is the power supply network RE of the vehicle that is responsible for supplying the complementary electric current.
On notera également que l'alimentation en courant électrique des moyens de chauffage MC par la (les) cellule(s) photovoltaïque(s) peut se faire soit directement via des câbles électriques qui les relient, soient indirectement via des câbles électriques et des moyens de contrôle (de préférence également connectés au réseau d'alimentation électrique RE). De telles moyens de contrôle sont destinés à contrôler l'alimentation en courant électrique des moyens de chauffage MC, notamment afin d'éviter qu'ils alimentent les moyens de chauffage MC lorsque cela n'est pas nécessaire. Note also that the power supply of the heating means MC by the (the) cell (s) photovoltaic (s) can be done either directly via electrical cables that connect them, or indirectly via electrical cables and means control (preferably also connected to the RE power supply). Such control means are intended to control the power supply of the heating means MC, in particular to prevent them from supplying the heating means MC when this is not necessary.
