number of control switches are available for active tuning to the
correct stand/ventilation capacity:
1. Wireless control switch mer three positions and timer
function.
2. Wireless control switch with two positions, an automatic
position and timer function.
3. Wireless
CO2 sensor
with control - 230V powered.

(optional) external
CO2 sensor
or RH sensor.
Note
If several controls are used, it may happen that the ventilation
position on the wired control switch does not correspond to
the current ventilation position (because the ventilation unit
has been set to a different control or sensor position).
