Functions 3; External Temperature Interlock - Mitsubishi Electric EB-50GU-A Instruction Book

7. Functions 3

7-1. External Temperature Interlock

Based on the temperature difference between the set temperature and the outdoor temperature, the set
temperature can be adjusted automatically. Making this control setting on the air conditioning unit at an entrance
of a building prevents extreme temperature change from distressing our bodies and sending us into shock. Click
[Functions 3] in the menu bar, and then click [External Temperature Interlock] to access the External Temperature
Interlock settings screen.
Note: AI controller (PAC-YG63MCA) is required to measure the outdoor temperature.
Note: This function is activated only when the operation mode is Cool or Dry.
Note: The External Temperature Interlock settings may not be accessible if logged in as a building manager.

(1) In the [Temperature Sensor] section, select a temperature sensor to measure the outdoor temperature with.
In the pulldown menu, the name of the temperature sensor that is connected to the AI controller or the AHC
will appear.
Note: Connect the temperature sensor to either the Analog Input 1 or Analog Input 2 port on the AHC.
(2) In the [Set Temperature Variation Range] section, select a maximum temperature value for each group to
be added to the set temperature.
For example, when [+4°C] (+8°F) is selected and the set temperature is 24°C (75°F), the set temperature
will be adjusted to maximum of 28°C (83°F) based on the temperature difference between the set
temperature and the outdoor temperature. When [+2°C] (+4°F) is selected, the set temperature will be
adjusted to maximum of 26°C (79°F).
Note: When the unit of temperature is Fahrenheit, the selected temperature value may not be added to the set
temperature accurately because 2ºC is used for the calculation first, and then the temperature in Celsius is
converted into the temperature in Fahrenheit.
