Description of operation for VALLOX 75/95VKL
Control of operation
Power supply to the unit is controlled with the 0/1 switch in the
distribution panel. There is also a maintenance / safety switch
SS
inside the unit. It stops power supply when the door of the unit is
opened.
Fan speed adjustment
The operation of the fans
S
and
E
of the unit is controlled with a
separate control centre
HS
, located in the ventilation zone, or with
a cooker hood.
Supply air temperature
Self-actuated control valve
V1
controls the operation of the postheating
radiator
R
, maintaining the temperature of supply air going out from
the unit at the setpoint value.
Heat recovery bypass
Summer-time bypass of the heat recovery cell
HR
is done manually
by turning the
HR
damper
H
in the bypass position for the summer.
Heat recovery defrosting
The defrost thermostat
T1
of the
HR
cell keeps stopping the supply air
fan
S
, thereby preventing the risk of the freezing in the
HR
cell. The
fan starts automatically as soon as the risk of freezing has passed.
The threshold temperature of the risk of freezing can be set at the
thermostat
T1
.
Water radiator defrosting
The defrost thermostat
T2
of the post-heating radiator
R
stops the unit
when the temperature of water radiator goes below the threshold
value, preventing the risk of freezing in the water radiator. This also
causes self-actuated one-way dampers
SP
to close, preventing the
flow of outdoor air to the unit. The unit starts automatically as soon
as the risk of freezing has passed. The threshold temperature of
freezing risk can be set at thermostat
T2
.
