Description of operation for VALLOX 75 / 95
Control of operation
Power supply to the unit is controlled with the 0/1 switch in the
distribution panel. There is also a service switch SS inside the
unit.
Fan speed adjustment
The S and E fans of the unit are controlled depending on
operating conditions with a separate 4-step (1, 2, 3 and 4)
control centre HS located in the ventilation zone, or with a
cooker hood.
Supply air temperature
Regulating thermostat T1 controls the operation of the electric
radiator R, keeping the supply air going out from the unit at the
setpoint.
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 antifreezing
The antifreezing thermostat T4 of the HR cell keeps stopping the
supply air fan S, thereby preventing the risk of the freezing of
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 T4.
Overheat protector of the electric radiator
The overheat protector T2 of the radiator R is triggered and
power supply to the heating unit is stopped, if the temperature
of the thermostat exceeds +80°C.
The overheat protector is reset manually.
