- Page 8 In automatic mode, a Sentera potentiometer with Modbus RTU communication can be connected to RTVS8. Via the optional DADCM analogue input module, RTVS8 series can be controlled via an external 0-10 Volt signal. To obtain demand based fan speed control, RTVS8 can be combined with a Sentera HVAC sensor.
- Page 9 RTVS8 115—230 VAC TRANSFORMER FAN SPEED CONTROLLER WITH MODBUS RTU COMMUNICATION Application example 4: Automatic mode - control via a digital potentiometer RTVS8 series To assure correct communication, the NBT needs to be activated in only two devices on the Modbus RTU network. If necessary, enable the NBT resistor via 3SModbus or Sensistant (Holding register 9).
