Room control unit WRF07 INC KNX

humidityventilationheating

The flush-mounted room operating unit with an interface for RS485 Modbus or KNX is used for set point adjustment. An outstanding feature is the possibility to overwrite the status via Modbus RS485. It furthermore includes a push button for triggering an ECO mode to save energy. The central knob is used as a rotary push button. The set point can be changed as required by turning the button accordingly. The device status is visualized by LEDs i.e. heating/cooling. • Application/type : Room operating unit • Purpose : Room Climate Control, Measure values • Measured values : temperature, relative humidity • Interface : KNX (TP) • Functions : temperature control, fan control, presence, night setback • Operating functions : setpoint adjustment temperature, fan stage adjustment, standby/presence detection, ECO function, status feedback via LED • Operating elements : rotary encoder/push button for setpoint adjustment/ECO function, button for fan stage adjustment • Configuration : BUS, ETS (KNX) • Network technology : KNX (TP1) • Operating range temperature (°C) : -10..+50 • Operating range humidity : max. 85% rH non-condensing • Accuracy temperature : ±0,3 K (typ. at 21 °C) • Measuring range humidity : 0..100% rH non-condensing • Accuracy humidity : ±2% between 10..90% rH (typ. at 21 °C) • Power supply : supply via BUS, 29 V = SELV • Display : 7 LEDs for displaying setpoint adjustment, labelling {- [thermometer] +}, 4 LEDs showing fan stage, labelling {[fan blades] I II III A}, LED for displaying the ECO mode function • Colour : pure white brilliant, pure white matt, aluminium, Jung aluminium • Protection (IP) : IP30, according to EN 60529
