Considerations on Temperature Signals IN485FGL001I000 Gateway VIRTUAL TEMPERATURE FUNCTION EXAMPLE CASE Imagine a very cold room with a temperature of 10°C. There's an AC indoor unit mounted in the ceiling, which is very high. The technician responsible for the BMS wants to raise the room temperature to 20°C. To achieve this, she accesses the console and sets this value in the BACnet object Setpoint_command (Analog Output)/Modbus register Temperature (user) setpoint (protocol address 4 / PLC address 5).
