WRF04 x RR

The surface-mounted room controller optionally with display showing the actual value serves for individual temperature control in living, hotel and office rooms. Possible operating elements are potentiometers, rotary switches, buttons and LEDs for setpoint adjustment, fan level selection, presence detection and visual feedback. Depending on the type, continuous or 2-point valves can be controlled for heating or cooling. The connection terminal in the lower housing part allows pre-wiring.
