The electronic DC hygrostat with integrated switch module is used to control heating and cooling equipment, filter
fans or signal devices through the relay. The hygrostat measures the relative humidity and can switch a signal
current via an internal relay. The external sensor can be positioned freely anywhere in the control cabinet for precise
measurement of the atmospheric humidity. Additionally, this hygrostat is available in versions that not only
measure the relative humidity via the external sensor, but also the temperature.
