Automatic humidity function
The control continuously checks the humidity during permanent base load. If the unit is operated without permanent base load, the unit starts at reduced speed (base load 20 m³/h) every 2 minutes for 30 seconds and measures the relative humidity.
The start delay is deactivated with the automatic humidity function turned on.
Once the unit is installed, it adjusts to the room humidity prevailing at that time (relative humidity). This humidity value is saved as the first reference value. The reference value does not have to be specified manually.
If the relative humidity falls below the reference value during operation, the newly established reference value is saved. The lowest possible reference value is 45 % relative humidity.
If the room humidity rises quickly, the unit is adjusted upwards in a continuously variable manner (depending on the humidity) to match the humidity. The maximum flow rate at 100 % r. h. is 40 m³/h, 60 m³/h or 100 m³/h, depending on the setting of V2.
If the humidity falls below the reference value, overrun operation mode starts with the set overrun time. The current reference value is then saved.
If the humidity does not fall below the reference value within 60 minutes, the unit switches to the set overrun mode and then switches off.
In the case of Light on, the unit starts up. If the light is switched off, the unit continues to run until the remaining overrun time has passed. The automatic humidity function is then assigned maximum priority again and controls the unit as described above.
Information
- ER EC/ER EC 2.1 units can also be operated using a light switch during operation with automatic humidity function.
- The interval operation is deactivated during the humidity operating mode.
- Overrun time:
- A set overrun time of 0 minutes is only valid for manual function with a light switch.
- For operation with automatic humidity function, the minimum overrun time is 3 minutes.
- For settings > 0 minutes, the overrun time is the same for manual (light switch) and humidity operating modes.
- Volumetric flows that can be set
V1: 20, 30, 40 m³/h
V2: 40, 60, 100 m³/h
