Gira System 3000 Relay 540300 Switch insert

System 3000 Relay Switching Module - Controls lighting and single-phase motors. - Manages electric underfloor heating and thermal actuators in combination with a room temperature controller attachment. - Adaptive zero point switching. - Connection of additional control points possible. - Automatic load disconnection. Adjustable delay times in five stages, non-retriggerable. - Test mode for functionality check. - Operates with neutral conductor connection. Combination with RF control attachment single/double for KNX: - Switching actuator channel single or heating actuator single. - Sensor channel single or double. - Local control of the System 3000 module is possible. - Wireless control of other devices for KNX as a sensor is possible. - Temperature measurement. - Function selection of the module for switching: Normally closed/open operation, stairwell function with disconnection pre-warning, scene function (16 scenes), lock function, time delays. Additional control point input as an extra control point for the System 3000 module or for wireless control of other devices for KNX as a sensor is possible. - Function selection of the module for room temperature control: Control of 230 V actuators, heating, cooling operation, heating and cooling operation, switching between heating or cooling operation via communication object or additional control point input. PWM and 2-point controllers, absolute and relative setpoint specification, heat demand control including cascading, valve protection function. Cyclical monitoring of floor temperature, service operation for valve output, frost protection function (automatic or via communication object), calibration of temperature sensor, boost function, summer and winter compensation, scene function (16 scenes). If the ambient temperature exceeds 35 °C, the connected load must be reduced.
