HEAT RECOVERY DEFROSTING FUNCTION
The defrosting of the heat recovery is active when the outside air temperature is lower than -15°C. The temperature is
checked every other hour (with 120 minutes interval). The supply air fan stops and the exhaust air fan runs on speed 3
when the defrosting is active. The defrosting is active at the most 8 % of the time. The over pressure function over rides
the defrosting function.
The defrosting function is activated by short circuiting the defrosting pins on the main board. The defrosting is in active when
the unit leaves the factory.
