Room hygrostat, surface-mounted, 24V AC to 230V AC, 35…85% r.H., two-way contact, external setting

The room hygrostat is used to monitor and control relative humidity, e.g. in business premises, apartments, conservatories, bathrooms, swimming pools, computer rooms and other spaces with a clean, non-aggressive environment. Relative humidity acting on a measuring strip activates a potential-free switch contact. The setpoint is adjusted using the adjustment knob located on the front. The setting range can be restricted.
