Function 1; Outside Temperature Interlock Function - Mitsubishi Electric AG-150A Instruction Book

8. Function 1

8-1 External Temperature Interlock
The purpose of this function is to avoid heat shock (physical shock caused by the extreme temperature difference when entering into a
building) during cooling operation. It adjusts the setting temperature in order to lower the temperature difference between indoor and
outdoor. To use this function, log in to the Web browser with the Maintenance User name and password, and then make a setting for AI
controller on the "Measurement" under "Function 1".
Note: Connect our AI controller (PAC-YG63MCA) to measure outside temperature.
Note: This function works when the operation mode is [cooling] or [dry].
Note: This function works for air conditioning unit group, but not for LOSSNAY, Air To Water (PWFY), or general equipment.
Note: When temperature are displayed in Fahrenheit, +2, +4, +6, +8°F may not properly be displayed because +1, +2, +3, +4°C Control
is excuted and then Celsius temperature is converted into Fahrenheit temperature inside the controller.
