Mitsubishi Electronics PAC-YG63MCA User Manual

The AI controller measures temperature and humidity; it also has an alarm capability if the measurement data exceeds 
defined setpoints. Historical measurement data can be displayed via only the G(B)-50A Web browser and TG-2000A. 
Temperature and humidity cannot be displayed on the G-50A LCD.
Furthermore, an alarm can be output if measurement data exceeds a preset upper or lower limit.
The AI controller also features a function that interlocks M-NET devices for indoor units, etc. set in advance and performs 
settings such as temperature control and operation/stoppage using measurement data values.

• The following parts should be included in your shipment:

* In addition to the parts listed above, see your local Mitsubishi Electric dealer to purchase the other parts necessary to operate this device (Refer to 

section 6-1). Furthermore, depending on the application, other Mitsubishi Electric parts may be required.
For details, refer to "6. Installation". 

*1: Supply electric power from a power supply unit for the transmission line or an outdoor unit. Furthermore, the power consumption factor of the M-

NET circuitry of this unit is "1/4" (equivalent to one ME Remote Controller).

*2: Configure the dip switch settings for the analog input method to use while referring to "9. Dip Switch Functions".
*3: The measurement error for the system includes the measurement error for this unit, sensor, and wiring.

a%FS (full scale) = a% × ([measurement range's upper limit value] - [lower limit value])

*4: Settings for the interlock function are performed from the Maintenance Tool. For details, refer to the operation manual for the Maintenance Tool.
*5: M3 and M3.5 are sizes of the screw on the terminal block (ISO metric screw thread). The number indicates the screw diameter (mm).

Time Backup 

During Power 

Failure

In the event of power failure or shut-off, the internal capacitor will continue to track time for approximately one week.

(The internal capacitor takes about 24 hours to fully charge; a replacement battery is not necessary.)

Installation 

Environment

Inside a control panel (indoors)

* Use this product in a hotel, a business office environment or similar environment.
