Die Aktivierung dieser Steuereinheit erfolgt alternativ mittels eines Schalters, einer Vorwahluhr oder auch mit einer Funkfernbedienung. Außentemperaturfühler und Fahrzeuginnentemperaturfühler, sowie Temperaturfühler im Heiz-/Klimagerät selbst, liefern die Parameter, die die Leistungen des Heiz- und Klimageräts steuern. Durch die Programmierung der Steuerlogik ist es möglich die vorgewählte Fahrzeuginnentemperatur durch eine Gleit regelung weitgehend konstant zu halten.This control unit is activated alternatively by means of a switch, a timer or also with a radio remote control. Outside temperature sensor and Vehicle interior temperature sensor, as well as temperature sensor in the heater / air conditioner itself, deliver the parameters that control the performance of the heater and air conditioner. By programming the control logic it is possible the preselected vehicle interior temperature by a glide regulation to be kept largely constant.

Inbetriebsetzung des Lüfters bei Warmluft heizungen - gleichzeitiges Einschalten der Zünd vorrichtung für den Brenner des Heizgerätes. Bei Kühlbedarf: Kompressorbetrieb, beispielsweise über eine Magnetkupplung, die den Kompressor bei Bedarf ein- und ausschaltet. 2) If heating is required: commissioning of the circulation pump for coolant in water heaters and / or. Commissioning of the fan in warm air heaters - simultaneous switching on of the ignition device for the burner of the heater. If cooling is required: compressor operation, for example via a magnetic coupling that the compressor Switches demand on and off.
- 3) Ca. 30 sec nach dem Einschalten wird bei Heizbe trieb die Brennstoffzufuhr zugeschaltet. Nach weiteren 5 sec wird das Brennluftgebläse einge schaltet.3) Approx. 30 seconds after switching on, Heizbe drove the fuel supply switched on. To The combustion air fan is switched on for a further 5 seconds switches.
- 4) Nach erfolgter Zündung/Flammbildung, die vom Flammwächter in der Brennkammer überwacht wird, schaltet sich die Zündeinrichtung ab.4) After ignition / flame formation by the Flame detector in the combustion chamber is monitored, the ignition device switches off.
Das fahrzeugseitige Heizgebläse oder alternativ ein im Kraftfahrzeug Heiz-/Klimakompaktgerät integrier tes Gebläse wird erst eingeschaltet, wenn entweder die Kühlrippen des Heizgeräte-Wärmetauschers oder die Kühlflüssigkeit eine Temperatur von ca. 55°C er reicht hat. Durch die Außentemperaturregelung werden folgende Betriebszustände geschaltet:The vehicle-side heater fan or alternatively one Integrate heating / air conditioning compact device in the motor vehicle The fan is not switched on until either the cooling fins of the heater heat exchanger or the coolant has a temperature of approx. 55 ° C was enough. Through the outside temperature control following operating states switched:
-
1) Bei Außentemperaturen von < -5°C schaltet das
Steuergerät auf "BOOSTER", d. h. es werden ca.
150% der Nennheizleistung für 5 min bis 10 min
erzeugt.
Die Regelung erfolgt über die Erhöhung der Taktfrequenz für die Brennstoffzufuhr und die Erhöhung der Drehzahl des Brennluftgebläses nach einer fest einprogrammierten Kurve, um eine optimale Verbrennung in der Brennkammer sicher zu stellen.
Die Außentemperatur wird durch einen Außentempe raturgeber gemessen.1) At outside temperatures of <-5 ° C, the control unit switches to "BOOSTER", ie approx. 150% of the nominal heating output is generated for 5 minutes to 10 minutes.
The regulation takes place by increasing the cycle frequency for the fuel supply and increasing the speed of the combustion air fan according to a permanently programmed curve in order to ensure optimal combustion in the combustion chamber.
The outside temperature is measured by an outside temperature sensor. -
2) Bei einer Temperatur der Kühlrippen des Heizge
rätewärmetauschers von ca. 70°C regelt das
Steuergerät die Taktfrequenz der Brennstoffzufuhr
und die Drehzahl des Brennluftgebläses auf 100%
Nennleistung ab.
Die Temperatur der Kühlrippen werden durch einen Oberflächen-Temperaturgeber gemessen.2) At a temperature of the cooling fins of the heater heat exchanger of approx. 70 ° C, the control unit regulates the cycle frequency of the fuel supply and the speed of the combustion air fan to 100% nominal output.
The temperature of the cooling fins is measured by a surface temperature sensor. -
3) Sobald eine Innentemperatur des Fahrzeuginnen
raums von beispielsweise (vorgewählten) 22°C
erreicht ist, regelt das Steuergerät die Takt
frequenz der Brennstoffzufuhr und die Drehzahl
des Brennluftgebläses derart ab, daß die gewün
schte Fahrzeuginnentemperatur im Bereich von 18°C
bis 25°C mit einer Genauigkeit von ± 2°C
gehalten wird (Gleitregelung).
Die Fahrzeuginnentemperatur wird über einen Tem peraturfühler gemessen.3) As soon as an interior temperature of the vehicle interior of, for example (preselected) 22 ° C is reached, the control unit regulates the clock frequency of the fuel supply and the speed of the combustion air fan in such a way that the desired vehicle interior temperature is in the range from 18 ° C to 25 ° C is maintained with an accuracy of ± 2 ° C (sliding control).
The vehicle interior temperature is measured using a temperature sensor. - 4) Beim Betrieb der Klimaanlage wird die Kühl leistung über die Einschaltdauer des Kompressors und die Drehzahl des Gebläses der Heiz- bzw. Kühlanlage geregelt. Der Kompressorbetrieb wird durch Temperaturgeber am Wärmetauscher und im Fahrzeuginnenraum gesteuert.4) When operating the air conditioner, the cooling performance over the duty cycle of the compressor and the speed of the fan of the heating or Cooling system regulated. The compressor operation is by temperature sensors on the heat exchanger and in Controlled vehicle interior.
Sowohl die Fahrzeugheizung als auch die Klimaanlage werden über einen getrennten EIN-/AUS-Schalter oder das Zündschloß abgeschaltet. Bei Standheizbetrieb übernimmt eine Vorwahlzeitschaltuhr das Abschalten. Bei Standheizbetrieb schaltet die Heizung automa tisch nach 30 min ab, um die Batterie durch die benötigte Energie (Zündvorrichtung, Lüfter, Brenn luftgebläse, Brennstoffzufuhr, Steuergerät) nicht zu stark zu belasten.Both the vehicle heating and the air conditioning are via a separate ON / OFF switch or the ignition switch turned off. In auxiliary heating mode a pre-selection timer switches off. In auxiliary heating mode, the heating switches automatically after 30 min to remove the battery from the battery required energy (ignition device, fan, burner air blower, fuel supply, control unit) not too heavy burden.
