Parameter settings
7.2.20

HG39: Soft start time

In heating mode, the burner is run at a lower output for the set time after starting.
7.2.21 HG40: System configuration
The heat generator is matched to the system by selecting from 7 preconfigured system versions.
Parameter HG40 can only be viewed and configured with the BM-2 programming unit or the AM display
module directly on the control module of the heat generator. This parameter affects both the function of
the feed/heating circuit pump and input E2
7.2.22

HG42: Header hysteresis

The header hysteresis regulates the header temperature within the set range by switching the heat
generator on and off.
TS cylinder:
The starting/stopping point for cylinder heating is reduced automatically by 2 K for stratification and in
order to avoid overheating. The software can detect when a TS cylinder is connected.
7.2.23

HG46: Excess boiler water temperature, header

H46 sets the excess temperature differential between the header temperature and the heat generator
temperature during header heating. The temperature of the heat generator continues to be limited by the
maximum boiler temperature (HG22).
7.2.24 HG47/49: CO
CO adjustments can be made for the heat exchangers to match the flue system by changing the fan

speed for burner operation - stage 1 (HG47) or burner operation - stage 2 (HG49).
7.2.25

HG56: Input E3

HG56 can be selected only if the "I/O module" expansion board is connected.
The flue gas damper function cannot be selected.
All other functions can be set as for HG13 (input E1).
7.2.26

HG57: Input E4

HG57 can be selected only if the "I/O module" expansion board is connected.
The flue gas damper function cannot be selected.
All other functions can be set as for HG13 (input E1).
7.2.27

HG58: Output A3

HG58 can be selected only if the "I/O module" expansion board is connected.
The flue gas damper function cannot be selected.
All other functions can be set as for HG14 (output A1).
7.2.28

HG59: Output A4

HG59 can be selected only if the "I/O module" expansion board is connected.
The flue gas damper function cannot be selected.
All other functions can be set as for HG14 (output A1).
7.2.29

HG60: Minimum burner hysteresis

Based on the maximum burner hysteresis (HG01), there is a linear reduction of the burner shutdown point
after the burner starts. After the hysteresis time (HG33), the burner switches off at the minimum burner
hysteresis (HG60).
Also see parameter HG01 diagram.
