continuous pump op.: Select for continuous operation
of the circulation pump in the exhaust air module.
pump speed: Set the desired speed for the circulation
pump in the exhaust air module.
time between defrosts: Here, you can set the minimum
time that must pass between defrosts of the heat ex-
changer in the exhaust air module.
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.
Defrosting warms up the heat exchanger so that the ice
melts and runs off via the condensation hose.
months btwn filter alarms: Here, you can set how many
months should pass before the heat pump notifies that
it is time to clean the filter in the exhaust air module.
Clean the exhaust air module's air filter regularly, how
often depends on the amount of dust in the ventilation
air.
activate cooling: Here, you can activate cooling via the
exhaust air module. When the function has been activ-
ated, the cooling settings are displayed in the menu
system.

Set when the addition is to start, the minimum run time
and the minimum temperature for external addition with
shunt here. External addition with shunt is for example
a wood/oil/gas/pellet boiler.
You can set shunt valve amplification and shunt valve
waiting time.
Selecting "prioritised additional heat" uses the heat from
the external additional heat instead of the heat pump.
The shunt valve is regulated as long as heat is available,
otherwise the shunt valve is closed.
