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

8. Function 1

8-1 Outside temperature interlock function

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.
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 (IC, AIC, KIC), but not for LOSSNAY, air to water supply equipment 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.
