As well as the regulated distribution of hot water it is also important for a comfortable climate that the room temperature is set correctly. A room thermostat measures the temperature using an integrated sensor. This is compared with the set specified value. If the specified value differs from the room temperature, the thermoelectric actuator connected to the room thermostat opens the valve of the heating circuit in question. Once the desired temperature has been reached, the thermoelectric actuator closes the valve.
The digital TOUCH HK room thermostat from Variotherm is operated via a display using sensor keys. The digital LED display can be dimmed. Heating is converted into cooling mode centrally via the change-over contact, or manually on the device.
