it gets cooler in autumn.

2.5. Heat recovery bypass
In winter use the heat recovery cell of
Vallox 132 E 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 bypassed in Vallox
132 E with the standard damper (A). The
damper can be released from the winter
position 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 so that the
radiator will not heat.

2.6. Air filtering
Vallox 132 E has both extract and supply air filtering before the fans and the
heat recovery cell. The unit comes standard with an F7 class fine filter (B),
which captures fine dust, pollen and dust not seen to the eye, and a G3 class
coarse filter (A) for insects and heavy pollen, for instance. There is a G3 coarse
filter (C) on the extract air side. The filters need to be in place in the unit
whenever ventilation is in operation (see Section 3.1.).

2.7. Filter guard (option)
A filter guard (L) available as an option monitors the cleanliness of the unit
and filters. The setpoint for the filter guard is adjusted individually for each
dwelling so that the filter guard indicator (M) lights up at fan speed 3 or 4
when the filters are clean (see Section 3.3.).
2.8. Fireplace switch function (option)
If the unit has been equipped with a fireplace switch (timer), it can be used
to stop the extract air fan for a certain period, such as 15 minutes, producing
overpressure in the ventilation zone. This makes it easier to light up a fireplace,
for instance.
The situation will normalise in a while, after the functions stops.
Note! The starting of the extract air fan may weaken draught in the fireplace.
During cold winter periods, the flowing of cold air to the extract ducts may cause
the antifreeze and antifrost functions to start. If the post-heating radiator does
not contain non-freezing solution, there is a freezing risk.
