As the room temperature exceeds the set threshold value, the controller switches off the circuit. Switching-on takes place as soon as the room temperature falls below the set threshold value. This way, the room temperature is kept at a pre-selected constant value. The device is adapted for the following functions: Temperature regulation:

– in rooms, offices
– in public or communal spaces
Heating control for:
– oil- or gas-powered central heating systems with circulation pump
– heat-storing electric stoves
Switching of:
– signal receptors or magnet switches
– direct switching of the power net.
Working temperature range: 5-30 °C
For some models provided with hand switch, additional functions are also available (main switch, night-time temperature lowering, switching of ventilators). The models equipped with alternant contact are also adapted for control of cooling systems.
