P11:
This parameter enables or disables the DHW solar func

tion. 1 = enabled, 0 = disabled.Visible only when solar NTC
sensor is connected.
P12:
This parameter value is important for the boiler to decide
whether burner will be on or off, when DHW solar function is
active (P11=1 and solar sensor connected). Refer to “DHW
solar function” section for details. Visible only when solar
NTC sensor is connected.
P13:
This parameter is functional at storage tank type models.
When storage tank is heated, boiler modulating set point is
equal to DHW-set point + this parameter value. Visible only for
storage tank type models.
P14:
Capacity of the pump at DHW
mode. Visible only for storage tank type models.
P15:
Max temperature, that can be adjusted by left dial when
setting central heating flow temperature.
P16:
This parameter is a read-only parameter which shows
the connection status of the boiler to the cloud.
P17:
This parameter is related to pump capacity modulation. If
difference between flow temperature and return temperature
is below this parameter value, pump decreases its capacity
1% each 4 seconds until minimum pump capacity is reached
which is adjusted by parameter P07. If difference between
flow temperature and return temperature is above this param
-
eter value, pump increases its capacity 1% each 4 seconds
until maximum pump capacity is reached, which is adjusted
by parameter P08.
P18:
Burner can operate up to CH se P18 value. After
burner is off. The following conditions must occur for the next
burner operation.
- Anti-cycling time is elapsed.
- Flow temperature < CH set point -P18
P19:
Min. temperature, that can be adjusted by left dial when
setting central heating flow temperature.
