GIRA 539500 Thermostat Flush mount 1 pc(s)

System 3000 Room temperature controller insert with sensor connection Features: - Switching of electric floor heaters and thermal actuators. - Output signal: Pulse width modulation (PWM) or two-point control (on/off). - Input for switching to cooling mode. - Interrupts the heating process after 60 minutes (overheating protection of a heater). - Connection of a remote sensor (accessory) possible. Combination with RF operating attachment 1-way/2-way for KNX - Heating actuator 1-way - Sensor channel 1-way or 2-way. - Local control of the system 3000 operation possible. - Radio control of other devices for KNX as a sensor is possible. - Temperature detection. - Function selection of the use for room temperature controller: Activation of 230 V actuators, heating, cooling, heating and cooling mode, switching of the heating or cooling mode by means of communication object or extension input. PWM and 2 point controller, absolute and relative setpoint preset, heat requirement control including cascading, valve protection function. Cyclic monitoring of the floor temperature, service mode for valve output, anti-freeze function (automatic or via communication object), adjustment of the temperature sensor, boost function, summer and winter compensation. Extension input is used to switch between the heating and cooling operation.
