Attention: With variation 20, frost protection should not
be set below 5°C or frost protection should be
deactivated if using a suitable collector fluid
to protect the heat exchanger.
Note:
With sensor short circuit, the pump is driven
at PS Speed Minimum, if the frost protection
temperature > –40°C has been set.
