Special
The sensor calibration function serves to balance out any deviations in the
measurements from the flow and return temperature sensors (T_boiler and T_return).
The temperature sensors are calibrated at the factory; sensor calibration is required
after replacing a sensor or carrying out a parameter reset.
Procedure:
Activation of the feed/heating circuit pump ZHP and correction of the flow temperature
sensor value (T_boiler) to the value of the return temperature sensor by setting
"FL correction".
For calibration, switch on ZHP, wait 10 minutes for the temperature to equalise, then
perform correction if necessary.
