DESCRIPTION OF THE PARAMETERS
Parameter 42 (2HD/32810): Summer operation (“summerkick”)
Every 24 hours, the pump and/or shut-off valve turns on for the period of time entered under this parameter.
Parameter 43 (2IA/32811): Ignition
This parameter allows the following ignition options to be set:
0 Ignition with internal ignition transformer
1 Ignition with internal and external ignition transformer
2 Ignition with external ignition transformer
Parameter 44 (2KM/32812): Step modulation
This parameter allows the step modulation to be turned off or specially dened.
0 Step modulation off
1 Step modulation increasing
2 Step modulation increasing and decreasing (not used)
Step modulation limits the boiler performance after the start of heating operation
Parameter 45 (2LA/32813): Effect of the fault relay
This parameter denes the effect of the fault relay.
0 Closes if there is a warning/blocking/fault
1 Closes if there is a blocking/fault
2 Closes if there is a fault
Parameter 46 (2NA/32814): Setting water pressure sensor - ADC/4 value at 0 bar
The set values of the water pressure sensor are used to indicate the actual water pressure via the voltage delivered
from the sensor. The value set here is responsible for the correct display of water pressure at 0 bar water pressure.
Between the two available set values (set value at 0 bar and 6 bar) there is a linear relationship.
Parameter 47 (2NB/32815): Setting water pressure sensor - ADC/4 value at 10 bar
The set values of the water pressure sensor are used to indicate the actual water pressure via the voltage delivered
from the sensor. The value set here is responsible for the correct display of water pressure at 10 bar water pressure
Between the two available set values (set value at 0 bar and 10 bar) there is a linear relationship.
Parameter 48 (2IB/32816): Extended external ignition time
If the parameters have been set for an external ignition (parameter 43 = 1 or 2), this parameter is used to set how
long it should stay active after the internal ignition time expires. This function is used to keep the stabilising ap
closed longer (if present).
Parameter 49 (2QA/32817): Reserve
(no effects)
