    5. SETTING THE DESIRED TEMPERATURE When the factory default temperature is set to 20°C and the factory default temperature is set to 20°C, the temperature of the thermostat switch on the connected heating device is lower than 19.8°C (connecting terminals 1 and 2) and higher than 20.2°C (disconnected terminals 1 and 2) under the switch sensitivity (±0.2°C).
  • Page 10 6. Heating Mode According to the change in room temperature and temperature setting, the device controls (switches on or off) the boiler or any other heating equipment connected to the appliance. When activated, the normally open contact pairs, i.e. No. 1 (NO) and No. 2 (COM), of the relay of the device clamp shut, and, as a consequence, the appliance connected to the thermostat is switched on.
  • Page 11 7. Cooling mode According to changes in room temperature and temperature setting, the equipment control (switch) is connected to the refrigeration equipment. When activated, the normally open contact pairs of the device clamp relay, i.e., No. 1 and No. 2 (COM), are closed, so that the appliance connected to the thermostat is on.
