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.
