27.3 Description
(Selection and more details in the AM display module/BM-2 programming unit installation instructions.)
27.3.1 System
In the "System" submenu, the contractor can make advanced system settings using system parameters
(see AM display module/BM-2 programming unit instructions).
27.3.2 Parameters/fullparameterlist
In the "Heating appliance" / "Parameters" / "Full parameter list" submenu, the contractor can make advanced
system settings using contractor parameters (see "Contractor parameters" chapter).
27.3.3 Special(sensorcalibration,pumpdown)
Sensor calibration
Thesensorcalibrationfunctionservestobalanceoutanydeviationinthemeasurementsfromtheow(boilertemperature)
and return temperature sensors. The temperature sensors are calibrated at the factory; sensor calibration is required
after replacing a sensor or carrying out a parameter reset.
Procedure:
Activationofthefeed/heatingcircuitpump(ZHP)andcorrectionoftheowtemperaturesensorvaluetothevalueof
the return temperature sensor by setting the correction value.
For calibration, switch ON the feed/heating circuit pump (ZHP), wait 10 minutes for the temperature to equalise, then
perform corrections if necessary.
