6.2 Frost protection
Regardless of the selected operating mode and settings for pump start and indoor temperature, the heat will be
activated if the outside temperature drops below approxi1.5°C (factory set).
This function is installed to protect buildings and heating systems from frost. The hot water circuit also has a
frost protection function that cannot be turned off.
For each heating circuit and hot water circuit it is possible to set a range of temperatures to enable the frost
protection.
If the pumps are turned off in manual pump mode, this function does not apply.

are activated every six hours for at least 10 minutes.
•

continuously.
