6.9.2.2 Frost protection
Explanation of [Frost protection]
This parameter is used to set the freeze protection limit
for the consumer controlled with the external heat
demand.
If the outside temperature falls below this value, the
external charging pump will be turned on to protect the
consumer. It will remain in operation until the outside
temperature is at least 2 °C higher than the [Frost
protection] temperature setting.
The factory setting for the freeze protection
threshold is +5 °C outside temperature to protect
consumers at risk from freezing (such as air heaters).
If there is no freezing risk for the connected
consumers, the freeze protection limit can be set
lower.
The [Service] access level is required to perform
modifications.
