Room temperature compensation
There may be a separate thermometer near to the room controller,
displaying a different value. If you wish to adjust the room
controller in accordance with the thermometer, you can use the
"calibration" function. Before calibrating the room temperature,
please consider the following points:
–
Is the thermometer more accurate than the room controller?
–
Is the thermometer directly adjacent to the room controller?
If the RC20 room controller measures a temperature that is 0.1 °C
below the value measured by the thermometer, then enter
"+0.1 °C" as the calibration value. The RC20 room controller then
displays a temperature that is 0.1 °C higher than the measured
value.

DHW heating

heating from the boiler.

USER NOTE
A thermometer may show temperature changes more slowly or
more quickly than the room controller, so never calibrate the room
controller when your heating system is in the process of cooling
down or heating up.
