616719, KNX room temperature controller UP / PI with key interface 4-fold, polar-white shiny, system M

Additionally available packaging sizes: 50

KNX room temperature controller / PI with 4-fold button interface. For System M. The device is a room temperature controller and a binary input. Depending on the mode of operation, the current temperature should value and the room temperature, a position size for the heating or cooling controller is transferred to the KNX. The temperature can be recorded either via the internal or external temperature sensor, which must be connected to the button interface. The button interface creates an internal signal voltage for the connection of max. four conventional buttons or potential-free contacts. Of this, two inputs can be used for the connection of weak current LEDs. With integrated bus coupler. The bus is connected via a bus terminal. Functions of the room temperature regulator: type of control: 2-point control, steady PIs control, switching PIs (PWM). Output: continuously in the range 0 to 100% or switching ON / OFF. Controller operation: heating with a controller output. Cooling with a regulator exit. Heating and cooling with separate control outputs. Heating and cooling with a regulator output. 2-stage heating with 2 control outputs. 2-stage cooling with 2 control outputs. Operating modes: comfort, comfort extension, standby, night reduction, frost / heat protection. Operation: The set value adjustment in the area with the wheel can be parametrized. Presence key functions can be parametrized / switched off. Valve protection, control deactivation. Functions of the key interface: switching, dimming, external blinds, valuers (dimming device, side site for light scenes with / without memory function, temperature sensor, brightness sensor). Key interface: up to 4 inputs, of which 2 can be used as outputs and one for the connection of the remote sensor. Output voltage: 5 V (SELV). Output current: max. 0.8 mA. Max. Cable length: Inputs / outputs max. 5 m, remote sensor max. 50 m. Material: thermoplastic. Color: polar white, shiny.
