The control unit has two separate controllers and a cascade controller. The unit has three operation modes for energy saving control functions. You can configure the outputs, setpoints and the controller dead zone separately for each operation mode.
You can connect up to two room units to one control unit for controlling up to two rooms with the same unit. The control unit supports the following devices as room units: RU, RT, RTX, TRI and ROU-S.
The control unit has 6 multifunctional inputs that support passive NTC10 or PT1000 sensors, 0...10 Vdc transmitter signals and contact functions. The control unit has 6 multifunctional outputs. They support 0...10 Vdc, 0...20 mA and 24 Vac actuators with different output functions, such as heating, cooling, 6-way valve control, 3-point actuator, fan speed or VAV.
The control unit supports the following communication protocols: Modbus RTU, Modbus TCP, BACnet MS/TP and BACnet IP.
You can configure the control unit settings with the MyProdual smartphone application. You can save the control unit configuration to Produal MyCloud cloud service with the application. You can also update the control unit firmware using the application.
