The electronic hygrostat HY 230 or HY 230 I is used to dehumidify or humidify closed rooms. It is suitable for all living areas and commercial spaces, including damp rooms such as bathrooms (please note the protection class when installing), laundry and drying rooms. The hygrostat uses an internal sensor to measure the room humidity and switches the fans, heat recovery devices or humidification or dehumidification devices on and off depending on the set target value. The HY 230 or HY 230 I is either mounted directly on a flush-mounted box or mounted on the wall using the surface-mounted mounting set APM HY 230. A dip switch on the circuit board can be used to set the dehumidification (factory setting) or humidification mode during commissioning. The switching status of the relay is indicated by a red LED in the housing.
