MERTEN 616819 KNX room temperature controller System M | Standard | polar white matt

![CDATA[KNX flush-mounted room temperature controller/PI with 4-way button interface. For System M. The device is a room temperature controller and a binary input. Depending on the operating mode, the current temperature setpoint and the room temperature, a control value for the heating or cooling controller is transferred to the KNX. The temperature can be recorded using either the internal or external temperature sensor, which must be connected to the button interface. The button interface generates an internal signal voltage for connecting a maximum of four conventional buttons or potential-free contacts. Two of these inputs can be used to connect low-current LEDs. With integrated bus coupler. The connection to the bus is made via a bus connection terminal. Functions of the room temperature controller: Controller type: 2-point control, continuous PI control, switching PI control (PWM). Output: continuous in the range 0 to 100% or switching ON/OFF.]]>
