VALLOX 70 COMPACT
POST-HEATING
For most of the year, heat recovered from the air being extracted is enough to warm the cold
air coming from the outside to a suitable temperature. If the heat of extract air is not enough,
air coming from the outside may be heated further with the radiator delivered with the unit.

Electric radiator
VALLOX 70 COMPACT comes standard with a max. 900 W electric radiator used for heating
supply air. The temperature of supply air is adjusted at the thermostat regulator located inside
the unit. Temperature adjustment range is +0...+25 °C.
It is advisable to set the thermostat at 0 °C in summer. In this case, the radiator does not heat
air, as the heat recovery cell is bypassed.
Note!
Post-heating represents comfort heating. It is not necessary for the functioning of the system
as such. What this means is that if the dwelling is heated by something else than direct
electric heating, it is worthwhile to minimize post-heating (supply air) temperature in order
to save electricity.
