Part no.: 2214 V-II 60-BM-I
Part no.: 2224 V-II 100-BM-I
The humidity control has a fixed switching point of 75 % RH (relative humidity) or responds to a rapid rise in humidity. When the unit is switched on, the fan starts after the measured values have been recorded for approx. 50 s (60 or 100 m3/h). When the unit is switched off, the fan runs on for 15 min. The fan switches off if no increased humidity value is measured during this period. The humidity sensor has a measured control range from 20 % to 95 % RH and constantly monitors the room air humidity. The humidity sensor starts the fan in the following situations:
- Rapid rise in humidity regardless of the current room air humidity
- The switching point of 75 % RH is exceeded
The integrated tropics function adapts the humidity sensor to the atmosphere in the room which changes according to the time of year. The tropics function also incorporates a running time limiter which switches the fan off after 12 h of uninterrupted service. Example of a rapid rise in humidity: The room humidity is 45 % RH. While the shower is in use, the fan starts due to the rapid rise in humidity, even if the 75 % RH switching point has not yet been reached.
- Fan running at 60 or 100 m3/h
- Run-on time of 15 min
- Measured control range from 20 % to 95 % RH
- Fixed switching point of 75 % RH
- Responds to a rapid rise in humidity regardless of the current room air humidity (RH)
- Running time limiter
