Exercising fans
On the setting c29 = 1-8 the last fans will hardly be activated during the winter.
To ensure that the fans are ‘exercised’ a test will be carried out every 24 hours to check whether all relays have been in operation.
The relays that have not been used will now be activated for 30 seconds, but with a pause of one hour between individual relays.
