Room hygrostat, surface-mounted, 24V AC to 230V AC, 35…85% r.H., two-way contact
The room hygrostat is designed for monitoring and controlling 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. Can be adapted for use in nearly all rocker switch ranges with cover set 50 x 50 mm or 55 x 55 mm.
