Page 60: Ambient Temperature And Virtual Temperature Function
IN485MHI001R000 Gateway Ambient Temperature and Virtual Temperature Function 9. Ambient Temperature and Virtual Temperature Function The IN485MHI001R000 gateway enables the use of a temperature sensor from the BACnet-based BMS. The reason for using this sensor could be that it is better positioned than the sensor in the indoor unit or the wired remote controller. - Page 61 Ambient Temperature and Virtual Temperature Function IN485MHI001R000 Gateway Set the Mitsubishi Heavy Industries AC system to read the temperature provided by the sensor inside the wired RC. NOTE This configuration must be performed by a Mitsubishi Heavy Industries authorized installer through the remote controller.
- Page 62 IN485MHI001R000 Gateway Ambient Temperature and Virtual Temperature Function The Virtual Temperature function can be activated with the gateway acting either as the header or the follower of the wired RC bus. • Procedure with the gateway acting as the header of the RC bus: Set the IN485MHI001R000 gateway as the header of the bus by setting the SW1-1 (DIP switch 1, position 1) ON.
- Page 63 Ambient Temperature and Virtual Temperature Function IN485MHI001R000 Gateway NOTICE Due to the formula applied by the Virtual Temperature function, the temperature reported by the AC system and the actual ambient temperature may differ. This must not be taken as an error, but as the normal behavior when the Virtual Temperature function is working.

Then, she looks at the BACnet object RoomTemperature_status (Analog Input), which reports the temperature sensed by the indoor unit: 24°C. At this point, the formula applied by the Virtual Temperature function is based on these numbers: 24-(19-20)=25.
