WRF04 x BUS

A surface-mounted room operating unit with an integrated temperature sensor and BACnet or LON interface. Optionally with a display showing the actual room temperature. The device can be mounted directly on the wall, on a flush-mounted box or in combination with a surface-mounted frame (see accessories). Predetermined breaking points for surface-mounted installations are integrated. Possible operating elements are set point 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.
