3.4 Heating/cooling
Commissioning and setting of the heating and cooling
equipment connected to the ventilation unit are per-
formed from this menu. Detailed instructions are sup-
plied together with accessories. As the factory setting,
the ventilation unit normally has internal post heating
that is controlled based on the supply air during the
heating season (post heating’s outdoor air limit). The
setting value for the supply air can be decreased in the
“Away” and “Travelling” operating modes.

The measurement value for the supply air and room air
temperature can be fine tuned from the
Temperatures/
control functions
menu, if the room temperature that is
measured with a separate thermometer deviates from
the temperature shown by the ventilation unit.
Important
Turning off the internal post heating or
lowering the limit value for the outdoor
temperature is not recommended, due to
the risk of condensation.

3.5 Anti-frost protection
Anti-frost protection on the ventilation unit works
automatically. The effect of the anti-frost protection can
be increased if necessary by increasing the “Efficiency”
value.

Reducing the strength of the ventilation means the
“Supply air limit” value prevents cold air from entering
the duct system.

exception of the fan speeds.
