MiniVent M1/100/120 F
– Activation threshold humidity: 60/50 %, 70/60* %, 80/70 %, 90/80 %
– Automatic humidity control system: low stage*, high stage
– Manual control (switch): low stage, high stage*
m Only an authorised electrician may change the settings!
The following functions are implemented:
Start-up delay
After activation, the fan will only begin to run after a set delay period. Thus, e.g. in case of joint activation/deactivation
with the light, a room can be entered temporarily, without the fan becoming operational.
Overrun time
After deactivation, the fan will continue to run and will automatically deactivate after a set period of time.
Automatic humidity control system
The microprocessor-controlled electronics detect two different types of humidity increase in the room air. It distingui-
shes between a slow and rapid humidity increase.
– High air humidity (slow humidity increase) .
In case of a slow humidity increase (e.g. due to washing, drying textiles, temperature reduction), the fan will be activated
above the set room humidity of 70 % RH (factory setting, using DIP switch) and it will run until the room humidity has
fallen by approx. 10 %, but at least for the set 6 minute overrun time.
– Event control (rapid humidity increase)
In case of a rapid humidity increase (e.g. due to showering, bathing), the fan will be activated before the set activation
threshold of 70 % RH is reached to eliminate the excessive humidity in the room as effectively as possible and to quickly
restore the comfort zone (40-70 % RH) in the room. As soon as the relative humidity has fallen to approx. 60 % RH
(factory setting), the fan will be deactivated, but no earlier than after the set overrun time of 6 minutes..
Runtime limiter
In cases with constant, excessive amount of humidity, the fan will be automatically deactivated after two hours, e.g. if
the incoming air is above the set relative humidity of 70 % (e.g. in case of a stormy atmosphere in the summer or if
there is constantly damp laundry in the room) or in case of an insufficient air exchange rate due to small-scale or
blocked air vent openings.
In this respect, there are two possible stop times depending on the situation:
a . Short stop time
The humidity has fallen below the activation threshold by the end of the overrun limit, but it has not yet reached the
deactivation threshold. The fan will then be deactivated, the short stop time of one hour will run.
Background: There was a humidity reduction during fan operation. However, the reduction was not enough to fall
below the deactivation threshold. A short stop time will be activated, because it is assumed that the humidity can be
effectively reduced after short break. Any humidity measurements are ignored during the stop time.
→ The required ventilation stages can still be operated. The stop time will continue in the background.
Only switching the mains on/off can clear the stop time.
b . Long stop time
The humidity has not fallen below the activation threshold by the end of the overrun limit. The fan will then be deacti-
vated, the long stop time of six hours will run.
Background: Since the humidity value has not fallen below the activation threshold, it can be assumed that further
ventilation makes no sense. A long stop time will be activated. Any humidity measurements are ignored during the stop
time.
