VALLOX 75/95
INSTRUCTIONS FOR USE
In winter use
the heat recovery cell of VALLOX 75 and VALLOX 95 recovers heat from the air leaving
the dwelling and uses it to heat the air coming from the outside. The damper is in down
position.
In summer use
when it is warm outside, it is unnecessary to heat outdoor air. The heat recovery cells are
then bypassed with the damper (A) coming standard with the unit. The damper is lifted up
and locked with a lock (B). In the summer position air flow through the cell is prevented,
and heat recovery bypass is activated. In summer set the electric post-heating thermostat
at 0
°
C position so that the radiator will not heat. If needed, the setpoint value of the water
radiator thermostat shall also be reduced.
Defrosting
Water condensing from extract air may freeze in the heat recovery cell. Freezing can be
prevented by stopping the supply air fan (standard function). The VKL model also includes
a water radiator defrost thermostat, which stops both fans when there is a risk of freezing
in the radiator.
Stopping of supply air fan
The defrost thermostat stops the supply air fan whenever the temperature of exhaust air goes
down to circa +4
°
C. The fan restarts when temperature has risen by three degrees, i.e.
to 7
°
C. The threshold value of the thermostat can be adjusted. The function starts at the
outdoor temperature of about -10…-15
°
C.
