If an on/off thermostat is used, it is advisable to protect any rooms
where there is risk of frost by using a frost thermostat. The radiator
Tout Tdhw
valve in a room where there is a risk of frost must, however, be open.
4 In rooms where there is a risk of frost, a frost thermostat (Tv)
should preferably be installed.

n Frost protection in combination with an outside sensor
The central heating system can also be protected against frost in
combination with an outside sensor. The radiator valve in a room
where there is a risk of frost must, however, be open. Connect the
outside sensor to the Tout terminals of the connector.
The frost protection functions as follows where an outside sensor is
used:
4 At an outside temperature lower than -10°C (can be set with
parameter p30): the circulation pump switches on.
4 At an outside temperature higher than -10°C (can be set with
parameter p30): the circulation pump continues to run and then
switches off.

Connect frost protection

When using a OpenTherm thermostat, a frost thermostat
cannot be connected in parallel to the On/off-OT
terminals. Implement frost protection for the central heating
system in combination with an external sensor.
