KNX object controller with 4-way button interfacePure white glossyThe flush-mounted continuous controllers and the object controllers combine the functions of a KNX bus coupler, an individual room temperature controller with setpoint specification 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 measuring the temperature in the floor. Two inputs can be parameterized as outputs (max. 0.8 mA). The controller function is used for individual 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 create a control variable. It can be used to control actuators with a continuous control signal as well as with a switching control signal.Controller: 5 operating modes: comfort, standby, night, frost or heat protection and controller lock (e.g. dew point operation). Heating and 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 operation of the controller can be locked. Valve protection function (valve is opened cyclically every 24 hours). Control types: continuous PI control, switching PI control (PWM) and switching 2-point control (on off). Temperature detection via an internal and/or external sensor (averaging for large rooms). Inputs: free assignment of the switching, dimming, blind and value transmitter functions to the inputs. Locking object for locking individual inputs. Behavior when bus voltage returns can be parameterized separately for each input. Telegram rate limitation. Switching function: two independent switching objects available for each input and can be activated individually, command can be set independently on rising and falling edges (ON, OFF, TOGGLE, no reaction). Dimming function: single-surface and double-surface operation, time between dimming and switching and dimming step size can be set, telegram repetition and stop telegram sending possible. Blind function: command can be set on rising edges (no function, UP, DOWN, TOGGLE), operating concept can be parameterized (step - move - step or move - step), time between short and long operation can be set, slat adjustment time can be set. Value transmitter and light scene extension function: edge (button as normally open contact, button as normally closed contact, switch) and value on edge can be parameterized, value adjustment on button via long button press for value transmitter possible, light scene extension with or without memory function. Temperature sensor function: One channel of the button interface can be used as an external temperature sensor for the room temperature controller.Outputs: Independent switching of the 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.
