Start-up delay: 45 sec., overrun time: 15 min.
Activation threshold humidity: 70/60 %
– The following functions are implemented:
1. Required ventilation
Regardless of sensor operation (F or P types), the stages can be activated or deactivated using a light switch via the
control inputs.
The last actuated stage always runs.
2. Start-up delay
Following the activation of the fan via the required ventilation (terminal 1/2/3), operation begins after the set delay time
(at all stages for multi-speed types). Thus, e.g. in case of joint activation/deactivation with the light, a room can be ente-
red temporarily, without the fan becoming operational. Factory setting approx. 45 seconds.
3. Overrun
The fan will continue to run after the deactivation of the required ventilation, and after the deactivation of all required
ventilations for multi-speed types, during the set time and it will then automatically deactivate. Factory setting approx.
15 minutes.
4. Changing the factory settings
Changes must be made before the installation of the fan unit. An installed fan unit must be removed from the casing
(see section 8.1), and the terminal box cover must be removed (see section 9.1).
5. Automatic humidity control system
The required ventilation control unit has priority over the humidity control unit. The humidity control system always
controls the required ventilation or the highest stage for multi-speed types. The microprocessor-controlled electronics
detect two different types of humidity increase in the room air. It distinguishes 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 15 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 (fac-
tory setting, using DIP switch), the fan will be deactivated, but no earlier than after the set overrun time of 15 minutes.
6. 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 be cancelled when actuated.
