In the Design System M. KNX room temperature controller for the commercial sector. Depending on the operating mode, the current temperature setpoint and the room temperature, a manipulated variable for heating or cooling control is sent to the KNX. The temperature can be recorded either by the internal or an external bus temperature sensor. The room temperature controller can be used for heating and cooling with continuously adjustable KNX actuators or for controlling switching actuators and heating actuators. The operating modes, setpoints and control functions are only 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. KNX software functions: Room temperature controller functions: Controller type: 2-point control, continuous PI control, switching PI control (PWM). Output: Continuous in the range 0...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 controller outputs. -2-stage cooling with 2 controller outputs. -2-stage heating and cooling with 4 controller outputs. Operating modes: comfort, extended comfort, standby, night-time reduction, frost/heat protection. Shifting of all setpoints. Saving of all setpoint temperatures and operating modes on reset. Monitoring of external temperature. Additional output of the manipulated variable as a 1-byte value with PWM. Reporting function for actual temperature, valve protection function. Operation: Only via bus telegrams.
Scope of delivery: With bus connection terminal and support plate. With plaster protection cover.
