The pump protection function can accomplish its task only if the boiler is in working order
in the summer, too. It is reasonable to set a low temperature level, e.g. +10°C, on the
thermostat for this period, to prevent the boiler from unnecessary start-ups when the
weather turns cold temporarily.
2.6 Calibrating the thermometer of the thermostat
There is a possibility to calibrate the thermometer of the thermostat (to correct the
measured temperature). In order to do this, 1st press the “
SET
” button to go to the main
screen. Then press the “
DAY
” and “
HOLD
” buttons one after the other. After this, the notice
“
” appears in place of the time characters, and the correction value appears in
place of the measured temperature (
°C by default). Following this, set the desired
correction value using the large
and
buttons between -
3.0 °C and +3.0 °C, in
0.1 °C increments. Finally, confirm the setting by pressing the “
SET
” button (if no buttons
are pressed for at least 15 seconds, the setting is automatically confirmed). After this
confirmation, the device goes back to the main screen. The correction of the measured
temperature takes effect a couple of seconds after the confirmation.
3. 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
