P07:
Minimum capacity of the pump during central heating
operation.
P08:
Maximum capacity of the pump during central heating
operation.
P09:
Capacity of the pump during central heating operation
burner off, pump post run or frost protection functions.
P00:
In case Opentherm thermostat is switched off (no heat
demand), boiler is either switched off (=0) or operates in redu
-
ction mode (=1)
P01:
Weather compensation building condition parameter. It
is used in flow setpoint calculation when outdoor sensor is
active.
Adjust it to ‘0’ if building has many windows to the south.
Adjust it to ‘1’ if building has few windows to the south.
P02:
Correction for outdoor sensor reading.
P03:
Boiler frost protection burner activation temperature.
If flow temperature drops below this par5 K value,
pump operates. If flow temperature still drops and goes below
this parameter value, the burner operates to heat up the water
temperature in the central Heating installation up to 20°C.
P04:
System frost protection activation temperature (in case
outdoor sensor is connected). This protection is only available
if an outdoor sensor is connected to the boiler. If the outdoor
temperature falls below this parameter value, boiler pump will
switch on.
P05:
This parameter adjusts the time, which is named as anti
cycling time, between 2 successive burner operation in central
heating mode. Anti cycling time is dependant to this parameter
value and CH set value adjusted by the customer. See the
following table;
P06:
Maximum central heating capacity can be restricted by
this parameter. For each model, max. CH capacity in percent
-
age is different as below;
