KNX object controller with push-button interface 4-gang System 55 pure white glossy The continuous flush-mounted controllers and the object controllers combine the functions of a KNX bus coupling unit, a room temperature controller with setpoint input and a binary input. Features: Four potential-free contacts can be connected to the binary input. Input 1 can be used to connect a remote sensor for temperature measurement in the floor. Two inputs can be parameterised as outputs (max. 0.8 mA). The controller function is used for room temperature control. The controller records the current room temperature with an internal or external temperature sensor and processes this with an adjustable temperature setpoint to a control value. Actuators with a continuous control signal as well as with a switching control signal can be controlled. Controller: 5 operating modes: comfort, stand-by, night, frost or heat protection and controller inhibit (e.g. dew point operation). Heating/cooling functions: Heating, cooling, heating and cooling, basic and additional heating, basic and additional cooling. Preset control parameters for common heating or cooling elements. Controller can be switched off (dew point operation) or controller or controller operation can be locked. Valve protection function (valve is opened cyclically every 24 hours). Control modes: Continuous PI control, switching PI control (PWM) and switching 2-point control (on-off). Temperature recording via an internal and or external sensor (averaging for large rooms). Inputs: Free assignment of the functions switching, dimming, shutter and value transmitter to the inputs. Blocking object for blocking individual inputs. Behaviour on bus voltage recovery can be parameterised separately for each input. Telegram rate limitation. Switching function: two independent switching objects are available for each input and can be enabled individually, command for rising and falling edge can be set independently (ON, OFF, TOGETHER, no reaction). Dimming function: One-surface and two-surface operation, time between dimming and switching and dimming step width adjustable, telegram repetition and stop telegram transmission possible. Blind function: Command on rising edge adjustable (no function, UP, DOWN, TURN), operating concept parameterisable (Step - Move - Step or Move - Step), time between short and long operation adjustable, slat adjustment time adjustable. Value transmitter and light scene extension function: Edge (push-button as NO contact, push-button as NC contact, switch) and value can be parameterised for edge, value adjustment for push-button via long push-button action for value transmitter possible, light scene extension with or without memory function. Temperature sensor function: One channel of the push-button interface can be used as an external temperature sensor for the room temperature controller. Outputs: Independent switching of max. two outputs. Notes : No separate bus coupler is necessary. When connecting the external inputs, the use of a switch terminal box is recommended. The object controller has no operating or display elements.
