Cooling with speed-controlled fans
When speed-controlled fans are used, the control is
carried out between the two adjustable limit values
DZMIN and DZMAX as a percentage value of the
control voltage (0-10VDC).
If the condition T
inside
> T
outside
+2° is given, the speed-
controlled fan is activated with the minimum speed
(DZMIN). If T
inside
= T
outside
+9°C the fan is operated at
full speed (DZMAX).
In between, the speed is controlled linearly
depending on the temperature conditions.

Comfort functions
Integrated time switch
With the integrated timer, active times for the
ventilation units can be set. In this way, the
ventilation remains switched on in the specified
time window regardless of the climatic conditions.
Frost protection
The frost protection function prevents the
monitored room from cooling down too much due
to ventilation when outside temperatures are close
to freezing point. For this purpose, a temperature is
set for the outside area at which the climate control
dispenses with ventilation cycles, even if the
climatic conditions would allow ventilation.
•
Standard setting: 3°C
•
Input range between 0-5°C in 1% steps
The frost protection function can be deactivated by
setting the value to 99.
Dry protection
Too dry room air disturbs the well-being. Dust and
other particles cannot be bound without sufficient
humidity.
The dry protection function ensures that the
humidity in the monitored room remains at a
healthy level for people and the building.
For this purpose, a desired humidity in the range
between 40% and 60% of the relative humidity can
be set in 5% steps in the control menu.

assembly and commissioning
The correct installation position is horizontal.
The device can be mounted on a wall in a few steps.
1:
To install the unit and to connect the power cable
and the supply air and exhaust air elements, open
the housing cover panels (1) on the left and right
edge of the housing cover by folding them open.
2:
Mark the 4 drill holes as provided.
