Merten Merten KNX Systeme 616725 Interface 616725

In the design of System M. The device is a room temperature controller and a binary input. Depending on the operating mode, the current temperature setpoint and the room temperature, a heating or cooling Stellgro?e for control on the KNX is sent. The temperature can be by the internal or by an external temperature sensor, which is connected to the terminal strip of the key interface to be connected? en is, must be recorded.. The key interface generates an internal signal voltage for connecting up to four conventional keys / potential-free contacts. It can be two inputs for connecting low-current LEDs. With integrated bus coupling unit. The bus is via a bus terminal. Software Functions KNX: Features Room Temperature Controller: Regulator type: 2-point control, continuous PI control, switching PI control (PWM). Output: constant in the range of 0..100% or switching ON/OFF. Controller mode: - heating with a controller output. - Cooling with a controller output. - Heating and cooling with separate control outputs. - Heating and cooling with a controller output. 2-stage heating with 2 control outputs. 2-stage cooling with 2 control outputs. Operating modes: Comfort, comfort extension, standby and night setback, frost/heat protection. Operation: Setpoint adjustment with adjusting wheel in the range can be parameterized, presence key function can be parameterized/off. Valve protection, control lock. Functions button interface: switching, dimming, shutter, encoders (dimming value generator, extension for light scenes with/without memory function, temperature encoder, brightness value encoder). Key interface: up to 4 inputs, of which 2 can be as outputs for connecting the remote sensor and a use. Output voltage: 5 V (SELV). Output current max 0.8 mA Max. Cable length: inputs/outputs max. 5 m, remote sensor max. 50 m. Accessories: ==> remote sensor for KNX room temperature controller UP/PI 616790. Material: thermoplastic brilliant, anti-bacterial. Smooth and even disinfecting surface with antibacterial effect. Color: similar to RAL 9016. Color: aktivwei? Glossy.
