4.8.7. Connect frost protection
n
Frost protection in combination with on/off thermostat
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
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.
4
Connect the frost thermostat in parallel with an on/off room
thermostat (
Tk
) to the
On/off-OT
terminals of the connector.
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.
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.
