Merten MEG6212-0460 button 2-gang plus, System M m.RTR aluminum

2-way push button sensor plus with room temperature controller. For System M. Convenient operating unit with 4 operating buttons, operating and status display and label field. The operating display can also be used as an orientation light. With room temperature controller and display. With 5 red LEDs. The room temperature controller can be used for heating and cooling with continuously adjustable KNX valve drives or for controlling switching actuators and heating actuators. With the white backlit display to show e.g. time, date, temperature and operating mode. Menu for setting standard operating modes, setpoint, working/non-working day (external trigger), display mode, time, switching times and brightness of the display. The buttons can be freely parameterized as button pairs (two-surface) or as individual buttons. With integrated bus coupler. The bus connection is made via a bus connection terminal. Functions of the push buttons: Switching, toggle, dimming, blind control (relative or absolute), pulse edges trigger 1-, 2-, 4- or 8-bit telegrams (differentiation between short and long operation). Pulse edges with 2-byte telegrams (differentiation between short and long operation), 8-bit linear controller, scene recall, scene storage, locking functions. Time control with synchronization, notification functions, cyclical reading of external temperature values, fan control, operating modes, setpoint shift. Functions of the room temperature controller: Controller type: 2-point control, continuous PI controller, switching PI controller (PWM). Output: continuous in the range 0 to 100% or switching ON/OFF. Controller operating 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-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, night reduction, frost/heat protection. Shifting of all setpoints, saving of all setpoint temperatures and operating modes on reset, external temperature monitoring, additional output of the control variable as a 1-byte value on the PWM. With bus connection terminal and carrier plate. Screw for dismantling protection. With protective cover for plaster. Material: Thermoplastic, elegant matt. Color: aluminum.
