Tank, sec. / prim. (Tank secondarily or primarily
connected)
1x053
Choose whether the heating of the DHW tank is dependent on the flow
temperature at S3.
See Appendix “Parameter ID overview”
OFF:
The DHW tank is placed on the secondary side of the
heat exchanger and the S3 temperature determines
the DHW heating.
ON:
The DHW tank is placed on the primary side of the heat
exchanger and the S3 temperature has no influence
on the DHW heating.
MENU > Settings > Application
Circ. P priority
1x055
Choose whether the DHW circulation pump should be ON during DHW
heating.
See Appendix “Parameter ID overview”
OFF:
The DHW circulation pump is switched OFF during DHW
heating.

The DHW circulation pump is not switched OFF during
DHW heating.
When the 'Circ. P priority' is set to OFF, the schedule for the DHW
circulation pump is overruled.
MENU > Settings > Application
Circ. P frost T
1x076
Set the outdoor temperature value at which the DHW circulation pump is to
be active to protect the DHW circuit against frost.
See Appendix “Parameter ID overview”
OFF:
The DHW circulation pump is not active.
Value:
The DHW circulation pump is active when the outdoor
temperature is lower than the set value.
MENU > Settings > Application
P frost T (circulation pump, frost protection temp.)
1x077
Frost protection, based on the outdoor temperature.
When the outdoor temperature gets below the set temperature value in ‘P
frost T’, the controller automatically switches ON the circulation pump (for
example P1 or X3) to protect the system.
See Appendix “Parameter ID overview”
OFF:
No frost protection.
Value:
Circulation pump is ON when the outdoor temperature
is below the set value.
Under normal conditions, your system is not frost protected if your
setting is below 0 °C or OFF.
For water-based systems, a setting of 2 °C is recommended.
If the outdoor temperature sensor is not connected and the factory
setting has not been changed to 'OFF', the circulation pump is always
ON.
