Temperature controller with LED display WRF04 RC x RS485 Modbus

IP30ambient temperatureflush-mount

The surface-mounted room controller (with optional display) provides a comfortable and individual temperature control in living spaces, hotel and office rooms. Available operating elements are set point potentiometers, rotary switches for fan stage selection, buttons for occupancy and LEDs for status feedback. Depending on the type, proportional 0..10 V or 2-point valves can be controlled for heating and cooling. The terminal in the back part allows for pre-wiring. • Application/type : Room controller • Purpose : Room Climate Control, Measure values • Measured values : temperature • Interface : RS485 Modbus • Functions : temperature control, fan control, heating + cooling relay, heating + cooling 0..10 V, heating relay, to control 6-way control valve, cooling 0..10 V, integrated controller, presence • Operating functions : setpoint adjustment temperature, fan stage adjustment, max. 5 stages, presence detection, status feedback via LED • Operating elements : potentiometer (P), labelling {[thermometer] - [scale] 0 [scale] +}, rotary switch (S), labelling {[fan blades]}, 2 fan stages, labelling {[scale] 0 I}, 3 fan stages, labelling {[scale] 0 I II}, 4 fan stages, labelling {[scale] 0 I II III}, 5 fan stages, labelling {[scale] A 0 I II III}, button (T) • Configuration : BUS, DIP switches • Output voltage : 0..10 V, 2x 0..10 V, min. load 10 kΩ, cooling, heating + cooling or to control 6-way control valve • Output switch contact : 2x contact NO, 1x heating, 1x cooling, 1x contact NO, heating, 1x output triac, heating, 2x output triac, 1x heating, 1x cooling, load max. 3 A, for 24 V =/~, for 24 V ~, floating • Input : 2x input for floating contact
