Humidity sensor maintenance
The humidity sensor (fig. 11 and fig. 12) can be cleaned with
a dry brush.
Removing and installing volute
The volute can be detached from the suction plenum by
gently pulling it out. You can now clean the suction plenum
(fig. 13).
Indication LED on the device
The green LED on the receiver PCB indicates the scenario
status of the MVS-15RH. When the LED repeatedly flashes
green once, the MVS-15 is operating normally. If the
LED repeatedly flashes green twice, the MVS-15RH is in
position 2 or 3 due to increased humidity levels. If the LED
repeatedly flashes green three times, the MVS-15RHB CO
2
is in position 2 or 3 due to increased CO
2
levels. If the LED
repeatedly flashes green four times, the MVS-15RHB is in
position 3 due to the timer scenario.
A short orange flash indicates that a signal has been
received from a CO
2
room sensor or remote control. The red
LED indicates a fault code on the device.
