Merten Merten KNX Systeme MEG6212-0344 Push-button module MEG6212-0344

In the design of System M. Comfortable control unit with 4 control keys, operating, status display and text field. The operating display can also be used as orientation light can be used. With room temperature controller and display. With 5 red LEDs. The room temperature controller for heating and cooling with infinitely adjustable KNX actuators or for the control of switching actuators and heating actuators can be used. With Wei? Backlit display for the representation of, for example, Time, date, temperature and operating mode. Menu for setting of standard operating modes, setpoint, working day/Day off (external control), display mode, time, switching time and brightness of the display. The keys are as button pair (two-scale) or as individual buttons can be freely parameterized.. With integrated bus coupling unit. The bus is via a bus terminal. Software Functions KNX: Functions Button: switching, switching, dimming, shutter (relative or absolute), edge triggers 1, 2, 4, or 8-Bit-Telegramme (distinction short/long press), edge with 2-byte frames (distinction short/long press), 8-Bit-Schieberegler, scene recall, scene storage, lock function, time-control with synchronization, signaling function, external temperature value cyclically read, fan control, operating modes, setpoint offset. Functions Room Temperature Controller: Regulator type: 2-point control, continuous PI control, switching PI control (PWM). Output: constant in the range 0...100% or switching ON/OFF. Controller mode: - heating with a controller output. - Cooling with a controller output. - Heating and cooling with separate control outputs. - Heating and cooling with a controller output. 2-stage heating with 2 control outputs. 2-stage cooling with 2 control outputs. 2-stage heating and cooling with 4 control outputs. Operating modes: Comfort, comfort extension, standby and night setback, frost/heat protection. Push of target values. Save all nominal temperatures and operating modes at reset. Monitoring external temperature. Additional output of the Stellgro?e as 1-byte value of PWM. Alarm function for actual temperature, valve protection function. Scene function. Operation: Menu. Delivery: with bus terminal and supporting plate. With screw for dismantling protection. With plaster protection hood. Material: thermoplastic brilliant. Color: white? Glossy.
