time between defrosts: Set the minimum time that
must pass between defrostings of the heat exchanger in
NIBE FLM.
When the exhaust air module is in operation the heat
exchanger is cooled so that ice builds up on it. When too
much ice builds up the heat transfer capacity of the heat
exchanger is reduced and defrosting is required. Defrost-
ing warms up the heat exchanger so that the ice melts
and runs off via the condensation hose.
months btwn filter alarms: Set how many months
should pass before the heat pump informs that it is time
to clean the filter in NIBE FLM.
Clean NIBE FLM's air filter regularly, how often depends
on the amount of dust in the ventilation air.
