Speed 3
Speed 3 time-limited (only when no other controllers are used alongside the 3-speed
switch): after 1 hour, the MVHR automatically switches back to fan speed 2
On/off function (only possible when no other controllers are used alongside the 3-speed switch) can be
disabled with jumper 9 on the PCB. This means the speed switches from Ventilation to Moisture Protec-
tion – the lowest fan speed.
Filter service indicator:
The period for the filter service timer (3 months) is set and stored and cannot be changed.
Once the period of 3 months has expired, the switch will indicate that a filter serice is necessary whereby the
LED for fan speed 1 flashes every second.
Once the filter has been successfully serviced i.e. cleaned or changed, the filter service timer on the switch can
be reset by pressing both OPERATING KEYS (and holding for 2 seconds) and the filter service indicator on the
switch will go out. Resetting is acknowledged by LED 1 flashing quickly 5 times.
In the event of a full MVHR service outside the above 3 month period, the timer can also be reset, without the
filter service timer having completed its runtime, by pressing both operating keys together and holding for 10
seconds. Resetting is acknowledged by LED 1 flashing quickly 5 times.
