Description
The wireless CO
sensor is used for wireless operation of ventilation
2
units from the M-WRG-II and M-WRG series constructed from 2020
onwards (excluding bus unit types). It can also be used to determine
the CO
concentration at an installation location selected by you,

provided that it is within the wireless range. The "CO
"Automatic mode" ventilation programs use the transmitted values
to automatically adjust the unit's air flow to the required ventilation
level. One wireless CO
sensor may be linked to each ventilation

The control button (item 1 in Fig. 1) is used to activate five different
ventilation levels/programs. The current selection is indicated by
one of the five green mode LEDs (item 3 in Fig. 1). The multi-
coloured status LED (item 2 in Fig. 1) signals the wireless sensor
and ventilation unit operating statuses. If the CO
exceeds 800 ppm (factory setting) in the "CO
mode" ventilation program, the ventilation level is increased contin-
uously up to max. 60 m
/h until the CO

drops back below 800 ppm. When it is started for the first time, the
wireless CO
sensor takes 2 minutes to calibrate itself so that it can

return stable values.
The wireless sensor is fixed to the wall with the dowels and screws
provided (see section 4.1). A 230 V connection is needed for oper-
