The central heating system can also be protected against frost in
combination with an outside sensor. The radiator valve in the frost-
sensitive room must be open.

The frost protection works as follows with an outside sensor:
AD-4100109-02
An outside sensor can be connected to the Tout terminals of the connector
(accessory). In the event of an on/off thermostat, the boiler will regulate
the temperature using the set point of the internal heating curve (F).
Various parameter settings can be used to change the internal heating
curve.

Various outside sensors can be used. Use below mentioned sensors or
sensors with identical characteristics:
Select the outside sensor with parameter AP056.

Frost protection combined with outside sensor
1. Connect the outside sensor to the Tout terminals of the connector.
If the outside temperature in lower than -10°C: heat demand from the
boiler.
If the outside temperature is higher than -10°C: no heat demand from
the boiler.
Important
The outside temperature before the start of frost protection can be
changed with parameter AP080 (as mentioned above the factory
setting is -10).
Connecting an outside sensor
1. Connect the plug from the outside sensor to the Tout connector.

An OpenTherm controller can also use this outside sensor. In that
case, the desired internal heating curve must be set on the
controller.
