INSTRUCTIONS FOR USE

5

2.4. Heat recovery bypass

In winter use, the heat recovery cell of VALLOX TSK Multi 50/80 recovers heat from the
air leaving the dwelling and uses it to heat the air coming from the outside.
In summer use when it is warm outside, it is unnecessary to heat outdoor air. The heat
recovery cell is then bypassed with damper (A) in VALLOX TSK Multi 50/80. The damper
is controlled using a separate 0-1 switch (not included in the unit delivery). The switch is
mounted in the flat at the same time with the electric installation for the unit. In the summer
position air flow through the cell is prevented, and heat recovery bypass is activated.

2.5. Air filtering

VALLOX TSK Multi 50/80 features coarse filtering of both extract and supply air before
the fans. The supply air side includes a G3 class coarse filter (B) and the extract air side
a G3 class coarse filter (C). The unit can also be equipped with an F7 fine filter (D), which
captures fine dust and pollen as well dust not seen to the eye. The filters need to be in
place in the unit whenever ventilation is in operation.

2.6. Antifreeze

Water condensing from extract air may freeze in the heat recovery cell. Freezing can be
prevented by stopping the supply air fan, or the unit can be equipped with a preheating
resistor, which is switched on as needed.

2.6.1. Stopping the supply air fan

Antifreeze thermostat T1 stops the supply air fan whenever the temperature of extract air
is below +5 

°

C after the cell. The fan restarts when temperature has risen by circa three

degrees to +8 

°

C. The limit of the thermostat (E) can be adjusted. If the unit includes a

preheating radiator (G), the supply air fan cannot be stopped.

2.6.2. Outdoor air preheating

The unit has possibly been equipped with a preheating radiator (F) at the factory. If that
is the case, antifreeze thermostat T1 switches the preheating radiator on whenever the
temperature of extract air goes below +5 

°

C after the cell. The preheating radiator switches

off when temperature has risen by circa three degrees to +8 

°

C. The preheating radiator

heats outdoor air before the heat recovery cell and prevents it from freezing. In very cold
temperatures the preheating radiator is not enough to heat maximum air flow to a sufficient
degree (in a temperature of -30 

°

C, maximum air flow is 30 dm

3

/s). The limit of the

thermostat can be adjusted.

The damper is controlled electronically with
a separate 0-1 switch mounted in the dwelling.
