OPERATING INSTRUCTIONS
Adjustment of supply air
temperature
Supply and extract air fl ow
adjustment potentiometer
Fireplace switch, fl ush
mounting (option)
Adjustment of supply air temperature and summer/winter
function
The temperature of air coming to the dwelling can be adjusted between circa +10 °C and
+30 °C. The unit has an automatic summer/winter function.
• When temperature adjustment is b10 and +30 °C. the heat recovery cell is
not bypassed. This means that the winter function is on.
• In the OFF position the summer function is on. That means that post-heating is not active
and the unit bypasses the heat recovery cell when outdoor air temperature is more than
+14 °C. The unit recovers heat when outdoor air temperature has gone down below
+12 °C.
• In the AUTO position the unit functions all year round as follows: The setpoint for post-
heating is +17 °C. The unit bypasses the heat recovery cell when outdoor air tempe-
rature is more than +14 °C. The unit recovers heat when outdoor air temperature has
gone down below + +12 °C. When bypass is on, post-heating is not active.
Fireplace switch function
It is possible to connect a timer-operated switch to the unit. The switch stops the extract air fan
during the time when the fi replace is heated. NOTE! The starting of the extract air fan may
weaken draught in the fi replace! In winter, this situation may disturb the winter function of the
unit. The situation will normalise in a while, after the fi replace function stops.
Winter function of ventilation unit
A threshold value has been set at the factory for the freezing of the heat recovery cell. When
the threshold is exceeded, the ventilation unit starts to melt the heat recovery cell by guiding
outdoor air fl ow to bypass the heat recovery cell.
A normal melting period takes from 15 to 45 minutes depending on the extent of ice on
the heat recovery cell and on the amount of extract air fl ow. The unit has been optimised to
operate on the factory settings in normal operation in dwellings and detached houses. The
winter function parameters can be adjusted for extreme conditions, such as a swimming bath,
but even then it is advisable to contact Vallox Maintenance.
Adjustment of relationship between supply and extract air
This feature may be useful when adjusting air fl ows at the valves during mounting. After the
valves have been adjusted, a user does not need, and must not, touch the adjustment. When
needed, supply or extract air fl ow can be reduced at the potentiometer.
When the potentiometer is approximately halfway, supply and extract air fl ow have not been
reduced. Turning the potentiometer anticlockwise reduces air fl ow on the supply side, and
turning it clockwise reduces air fl ow on the extract side.
Maintenance reminder
The unit reminds of the need for maintenance every six months if an indicator (not standard)
has been connected to the connectors of the fault signal relay. The indicator then blinks at
one-second intervals. The maintenance reminder is reset when the door of the ventilation unit
is opened. See the maintenance instructions for information on the necessary maintenance
activities.
Four-step control switch
Fan speed adjustment
The fan speed of a Vallox ventilation unit can be controlled with a control switch (option), with
a separate cooker hood (option) or directly with a 0-10 V voltage signal.
Speeds 1, 2, 3 and 4 can be selected at the control switch.
1. Operation during absence. When the dwelling is empty, ventilation can be reduced
temporarily.
2–3. Normal operation. In normal operation, air has to be replaced once every two hours.
4. Boosted operation. Cooking, taking a sauna bath, washing, drying clothes, using the
toilet, having guests or a corresponding situation may cause a need for higher ventila-
tion than in normal operation.
