Notes:
Before a parameter reset, make a note of the settings and statistical data.
After the parameter reset, carry out a sensor calibration.
The sensor calibration function serves to balance out any deviations in the
measurementsfromtheow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ow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.
