Merten MEG6221-0325 room thermostat, f.Objektbereich aktivwhite glossy Sys.M

Room temperature controller for properties. For System M. KNX room temperature controller for properties with integrated bus coupler. Depending on the operating mode, the current temperature setpoint and the current room temperature, a control variable for heating or cooling control is transferred to the KNX. The temperature can be recorded either via the internal or an external bus temperature sensor. 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. Operating mode, setpoint, control functions can only be set via the bus. The device has no operating or display elements. With integrated bus coupler. The bus is connected via a bus connection terminal. Functions of the KNX software:. Functions of the room temperature controller: Controller type: 2-point control, continuous PI controller. Switching PI controller (PWM). Output: continuous in the range from 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-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. Monitoring function for the actual temperature, valve protection function. Operation: only via bus telegrams. Contents: With bus connection terminal and carrier plate. With protective cover for plaster. Material: Thermoplastic, antibacterial. Color: similar to RAL 9016. Color: Active white, glossy.
