WRF04 x BUS

A surface-mounted room operating panel with integrated temperature sensor. The device can be mounted directly on the wall, on a flush-mounted box or in conjunction with a surface-mounted frame available as an accessory. Predetermined breaking points for surface-mounted installations are integrated. Possible operating elements are potentiometers, LEDs, buttons and rotary switches for setpoint shifting, fan level adjustment, presence detection, control of other devices and visual feedback. The connection terminal in the lower enclosure part allows pre-wiring.
