INSTRUCTIONS FOR USE
Select Basic display 2 if you want to control
the fan speeds in five different steps.
The ventilation unit fans, the heat exchanger
and air heater, if fitted, are stopped.
Select if you want to use the weekly timer.
Four different programs can be selected on
the weekly timer, with the Away/Home/Boost
fan speeds. However, a manual change from
the control panel will bypass (override) the
weekly timer functions.
The contrast in the control panel display can
be adjusted by entering a higher or lower digit
in the menu.
This menu shows the ventilation unit’s model.
Set the required start temperature and fan
speed for the summer night cooling function.
The summer night cooling function utilises
cool night air to cool down the home. When
the function is activated, the rotary heat
exchanger will stop.
Conditions for activation:
• the reheating function is not active.
• The extract air temperature is above 22 °C.
The outdoor air temperature is above 16
°C, but at least one degree lower than the
extract air temperature.
You can change the temperature limits
and select fan speeds. The standard setting
is that the fan operating mode will not
change when the function is activated.
Available only in models equipped with
air heater.
Set the required supply air temperature (fac-
tory setting: 17 °C). The ventilation unit’s
heat exchanger and air heater (accessory) are
automatically activated so that the required
temperature will be reached. The supply air
temperature should be lower than the room
temperature, so that the supply air and room
air will mix together well. Note that a high
temperature setting will also increase the
consumption of electric power.
Select the desired basic display.
