Choose to permit a speed reduction of the extract air
fan when using a cooker hood whose extract air does
not pass through the ventilation unit.
Enable the cooker hood function and set the Home
mode’s compensation value so that the airflows are kept
in balance. Fine tune the boost compensation value too
if necessary.
3.3 Sensor
Select which sensor you wish to use to measure the
room air temperature.
The menu shows the temperature measured by the se-
lected sensor. If, for example, the temperature measured
by the sensor differs from the value from a temperature
sensor installed in a different location in the same room,
the temperature sensor can be calibrated by changing
the room air fine tuning value.
3.4 Control functions with optional items
of equipment
If the unit is to be controlled with optional equipment,
set the switch input for this.
There are three switch inputs on the ventilation unit’s
PCB that need to be configured. Specify which switch is
connected to each input. The options are input signals
from the following external switches: fireplace, travel-
ling, central vacuum, cooker hood, boost and filter
guard. You can change the relative priority of the func-
tions if necessary.
3.5 Remote supervision (DDC)
If the ventilation unit is to be operated remotely, choose
to put remote control into service and set the desired
temperature reductions. If the ventilation unit’s fan
control is handled by DDC, you cannot change the oper-
ating mode from the Smart control panel. See a detailed
description of remote control in the section “Technical
data” / “Supervision (DDC)”.
Variable control occurs between the voltages 2 V - 5 V
- 8 V. The ventilation then switches variably between op-
erating modes Away - Home - Boost. Otherwise, control
is performed according to the normal DDC control.
3.6 Damper motors
If external duct damper motors are used, choose to en-
able control. The damper is then regulated to the open
position when the ventilation unit is operating.
3.7 Re-heater (not Econo)
Here you select whether you wish to use the electric air
heater for re-heating to heat the supply air when the
heat exchanger’s power is not sufficient for reaching the
preset supply air temperature.
3.8 Anti-frost protection
Anti-frost protection works automatically.
3.9 Restore factory settings
Resets all settings made from the control panel, with the
exception of the fan speeds.
