FIREPLACE SWITCH FUNCTION (option)
Speed selector
Cooker hood PTXP/I 130
Speed selector
The VALLOX 70 COMPACT delivery includes a four-step switch. The flush-mounted switch
can be mounted in a standard instrument box. The switch can be used to select four of
the seven speeds for the unit. The speeds selected for the unit are 1, 2, 3 and 4. An
expert can select different speeds at the transformer of the unit.
Control with a cooker hood
When desired, cooking smoke abatement can be connected directly to VALLOX 70
COMPACT and controlled with cooker hood VALLOX PTXP / I 130.
Winter use
In winter use the heat recovery cell of VALLOX COMPACT recovers heat
from the air leaving the dwelling and uses it to heat the air coming from the
outside.
Summer use
The heat recovery cell is bypassed in VALLOX 70 COMPACT with an in-built damper.
In the summer position air flow through the cell is prevented, and heat recovery
bypass is activated.
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 the 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.

Post-heating radiator
The post-heating radiator of the VALLOX 70 COMPACT unit is a PTC resistor, which aims at
heating the air blown to the rooms to preset temperature. The temperature of supply air is
adjusted at the thermostat regulator located inside the unit. The post-heating radiator is a PTC
resistor, the laminas of which are live when the unit is in operation. The PTC resistor must not
be touched before the unit has been switched off. It is advisable to set the thermostat at 0 °C
in summer. In this case, the radiator does not heat air.
Preheating radiator
Vallox 70 Compact comes standard with a preheating radiator. The antifreeze thermostat
switches the radiator on instead of stopping the outdoor air fan. The radiator heats outdoor
air before the cell, preventing 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 minus 30
degrees Celsius, maximum air flow is 30 dm3/s, which corresponds to speed 2 or 3). The
threshold values for automatic antifreeze can be adjusted inside the unit. The tubular preheating
radiator is connected to two overheat protectors. One of the overheat protectors is automatically
resetting (type BTS) and the other is a cut-off one (type BTC, cut-off). If the overheat protectors
have tripped, switch off the unit for a moment.

Filter guard
VALLOX 70 COMPACT can be equipped with an optional filter guard.
The filter guard indicator lights up at speeds 3 and 4 when the filters
are clean; this is normal and does not call for any maintenance activities.
If the indicator does not light up at speed 4, the pressure in the ventilation
ductwork of the building differs from the factory setting. When needed,
an expert may change the setpoint. If the filter guard symbol already lights
up at fan speed 1 or 2, the filters need cleaning. If they are clean, the lighting
up may be caused by a clogged up dense mosquito net installed against
mounting instructions in the external grille or by the closing of the supply
air valves in the rooms.

Description of operation VALLOX 70 COMPACT / VALLOX 70K COMPACT
Control of operation
Power supply to the VALLOX 70 COMPACT unit is controlled
with the 0/1 switch in the distribution panel. There is also a
maintenance switch HK inside the unit.
VALLOX 70K COMPACT is equipped with a plug. There is
also a maintenance switch HK inside the unit.
Fan speed adjustment
The Sand Efans of the unit are controlled depending on
operating conditions with a separate 4-step (1, 2, 3 and 4)
switch HS located in the ventilation zone, or with a cooker
hood.
Heat recovery bypass
Summer-time bypass of the heat recovery cell HR is done
manually by turning the HR damper Hin the bypass position
for the summer.
Supply air temperature
Regulating thermostat T1 controls the operation of the electric
radiator JL, keeping the supply air going out from the unit at
the setpoint.
Preheating of outdoor air
Regulating thermostat T2 controls the operation of the electric
radiator EL as follows: the radiator heats outdoor air before
the cell and prevents the heat recovery cell from freezing. In
very cold temperatures the preheating radiator EL is not enough
to heat maximum air flow to a sufficient degree (in a temperature
of minus 30 degrees, maximum air flow is 30 dm3/s, which
corresponds to speed 2 or 3). The threshold of thermostat T2
can be adjusted inside the unit.
Heat recovery defrosting
(alternative to preheating radiator)
The anti-freezing thermostat T2 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 freezing
risk can be set at thermostat T2.
Fireplace switch function
The unit can be equipped with an optional fireplace switch
FS. It can be a timer equipped with opening points. Timing
period can be 15…30 minutes.
Alarms
Pressure difference switch PDS is an optional device for controlling
pressure difference on the supply air side. If the pressure
difference rises above the setup, because of dirty filters or
clogged ducts, an indicator is lit on the front panel of the unit.

a condensing water pipe to a water
seal or a floor drain where hot
washing or shower water goes.
(If hot washing water goes to the
floor drain and condensing water
seal gets dry during the summer,
steaming air is released from the
drain to the unit's negatively pres-
sured outlet side, which causes
water to condense from the air in
the pipe. A condensed water drop
may generate an audible sound
from the floor drain. The sound
may be generated in winter as well
if the water seal of the condensing
water pipe is not filled and does
not prevent air from flowing.
Air flow and the formation of water
drops in the condensing water pipe
should be prevented.)
Examples of condensing water connections
Normally to the floor
drain
May generate sound when the
water seal gets dry.
When there is no condensing water, the water seal
may get dry in 1 to 4 weeks.
Normally to the floor
drain with a long water
seal
A long water seal ensures
soundlessness for a long time.
Straight to the floor
drain without a water
seal
The downward slope of the
pipe is so steep that a water
drop generating sound
cannot remain in the pipe.
Normally to the floor
drain through a funnel
No water seal. No sound
because there is no suction
in the pipe. The unit sucks
replacement air from the
funnel.
Normally to the floor
drain through a non-
return valve
The valve prevents air flow in
the pipe but lets condensing
water flow into the floor drain.
No sound.
To the collector
No sound.
(Blocks of flats)
Normally to the floor
drain
The pipe has a fork which
decreases suction from the floor
drain. No sound. Water seal
not necessary. The fork can also
be used to fill the water seal if
such a seal is used.
To the water seal in
the wash basin
May generate sound when
the water seal gets dry.
