KNX 4V DRUKKNOP+THERMOSTAAT, WIT, SYST M

Push-button 4-gang plus with room temperature control unit. For System M. Convenient control unit with 8 operating buttons, operating and status display and labelling field. With 9 red LEDs. The operating display can also be used as an orientation light. With room temperature control unit and display. With integrated piezoelectric buzzer to display alarm states and IR receiver. All functions of the respective buttons can be controlled via IR remote control. The room temperature control unit can be used for heating and cooling with infinitely adjustable KNX valve drives. Or to trigger switch actuators and heating actuators. With the white backlit display for showing e.g. the time, date, temperature and operating mode. Menu for setting default operating modes, setpoint value, working/non-working day (external trigger), display mode, time, switching times and brightness of the display. The push-buttons are freely parameterisable as push-button pairs (dual-surface) or as single push-buttons. With integrated bus coupler. The bus is connected using a bus connecting terminal. Functions of the push-buttons: Switching, toggling, dimming, blind control (relative or absolute), pulse edges trigger 1-, 2-, 4- or 8-bit telegrams. Distinction between short and long operation, pulse edges with 2-byte telegrams (distinction between short and long operation), 8-bit linear regulator, scene retrieval, scene saving Disable functions, timed control with synchronisation, notification functions, the cyclic reading of external temperature values, fan control, operating modes, move setpoints. Functions of the room temperature control unit: Controller type: 2-step control, continuous PI controller, switching PI controller (PWM). Output: continuous in the range 0 to 100% or switching ON/OFF. Controller mode: Heating with one controller output. Cooling with one controller output. Heating and cooling with separate controller outputs. Heating and cooling with one controller output. 2-step heating with 2 control outputs. 2-step cooling with 2 control outputs. 2-step heating and cooling with 4 control outputs. Operating modes: Comfort, comfort extension, standby, night reduction, frost/heat protection. Move all setpoints, save all setpoint temperatures and operating modes when reset. External temperature monitoring, additional output of the control value as 1 byte value on the PWM. Monitoring function for the actual temperature, valve protection function. Scene function. With bus connecting terminal and supporting plate. Screw for protection against dismantling. With protective hood for plaster. Material: thermoplastic brilliant. Colour: white, glossy.
