5. OPERATION OF THE INSTALLED THERMOSTAT
The thermostat controls the device connected to it (e.g. gas boiler or
pump) based on the temperature measured by it and the currently
set temperature, taking into account the switching sensitivity of
the thermostat (factory default ±0.2 °C). This means that if the
thermostat is set to heating mode and 22 °C, then with a switching
sensitivity of ±0.2 °C the connection points 1 (NO) and 2 (COM) of
the output relay are closed below 21.8 °C (heating is turned on) and
opened at temperatures above 22.2 °C (heating is turned o). In
cooling mode, the relay switches exactly the opposite way.
The closed status of the output relay terminals 1 (NO) and 2 (COM)
is indicated by the “HEAT” or “A/C” icon in the lower left corner of
the display, depending on the selected operating mode.
