  • Fig. IIa shows a sequence of adjusting a target temperature together with the respective control pulses of the control computer 16 to the motor 18 for the tactile feedback. Shown is the course of a target temperature 42, starting from a base temperature, for example 20 ° C. The change in the target temperature 42 is effected via a rotational movement, as described above.
  • a control pulse should be triggered by the control computer 16.
  • the target temperature 42 from the base temperature for example, constantly first by 5 ° C and then increased by 10 ° C.
  • the setpoint temperature exceeds one
  • the setpoint temperature falls below a lower limit range.
  • the user can continue to make a rotational movement and virtually reduce the target temperature further.
  • the setpoint temperature then remains at the limit value until an operation in the other direction takes place.
  • a longer control pulse 52 can be output. This can be output, for example, as long as a change in the setpoint temperature 42 is made and this is below the lower limit.
  • the long impulse gives the user immediately a permanent tactile feedback that he can not change the target temperature in the direction he wants.
  • FIG. IIb A course of a pulse 48 or a pulse 52 is shown in FIG. IIb. It can be seen that the pulse is formed from an alternating voltage, the

Abstract

Thermostat pour installations de chauffage, climatisation et/ou ventilation, comprenant un corps de base, un capteur de température agencé sur le corps de base, un élément de réglage agencé sur le corps de base et un boîtier entourant au moins partiellement le corps de base. Selon l'invention, pour faciliter l'utilisation, un circuit de commande détecte une utilisation du thermostat sur le boîtier et, en réponse à la détection d'une utilisation, active un retour tactile.
