Functions 3; External Temperature Interlock - Mitsubishi Electric AG-150A Instruction Book

7 Functions 3

7-1 External Temperature Interlock

To use external temperature interlock, click [Function 3] on the menu, and then click [External Temperature
Interlock]. Air conditioning group can be set for this control.
By setting this control on the air conditioning unit at an entrance, our physical shock (heat shock) caused by
the extreme temperature difference can be reduced when entering into a building.
Note: If PAC-YG50ECA Expansion Controllers are connected, Expansion Controller system selection buttons will appear. Select
the desired Expansion Controller (EC1, EC2, or EC3), and make the settings for each system. Make the settings with the
Expansion Controllers properly connected.
Note: Connect our AI controller (PAC-YG63MCA) to measure outdoor temperature.
Note: This function works when the operation mode is [cooling] or [dry].
Note: When connecting AG-150A controllers by connecting an Expansion Controller to the system, external temperature interlock
settings should be made only on one of the AG-150A controllers.
