SIEMENS RDG405KN Wall-mounted room temperature controller for VAV applications
Room temperature and air quality controller for VAV applications, for a single-channel system with electric heating, heating/cooling register or radiator, the controller works with an external CO2 sensor connected via the KNX bus or with an analog 0 - 10 V signal connected to input U1; the VOC sensor can only be connected to analog input U1 (0 - 10 V), supply voltage 24 V AC, consumption from the bus 5 mA.
1x output (0-10 V DC) for the VZT damper actuator, 1x triac additional control output (2-point, PWM, 3-point), KNX TP1 communication (S-Mode, LTE-Mode)
