VENTILATION THE RIGHT WAY
V E N T I L A T I O N & H E A T R E C O V E R Y
8.2.3 “Humidity control”
Symbol
Default view
Description
The ventilation unit runs constantly at the lowest ventilation
level (15 m
3
/h*). If the relative room air humidity exceeds
60 % RH, the ventilation level is increased continuously up to
max. 60 m
3
/h until the humidity in the room drops back below
60% RH.
NOTICE
To ensure dehumidification, the ventilation unit compares the
humidity of the supply air and extract air. The ventilation unit
ventilates at the lowest level when the humidity of the supply
air is greater than that of the extract air, which means that
dehumidification is not possible.
8.2.4 “Mixed gas/CO
2
control”
Symbol
Default view
Description
The ventilation unit runs constantly at the lowest ventilation
level (15 m
3
/h*). A sensor monitors the air quality in the room
(CO
2
and various pollutants in gaseous form). If the limit
of 600 ppm is exceeded, the ventilation unit calculates the
optimum air renewal and sets the required ventilation level in
the range from 15 - 60 m
3
/h fully automatically.
NOTICE
—
When it is started up for the first time, the ventilation unit
must remain switched on for at least 15 minutes without
interruption so that the VOC sensor can be calibrated.
►
Make sure that the air is not severely contaminated
during the calibration phase by solvents, for example.
— When you switch on again, it will take roughly 5 minutes
for the sensor to recalibrate.
* The ventilation level can be reduced from 15 to 0 m
3
/h at the factory or using the optional wireless remote control
M-WRG-FBH. The ventilation unit switches to sniffing mode and interrupts its operation for the set pause time (set to
60 minutes at the factory). The relative humidity or mixed gas/CO
2
concentration is then checked for a 5-minute period.
If the corresponding limit is exceeded, the ventilation unit switches back to ventilation mode.
