Mitsubishi PAC-YT53CRAU-J Remote Controller (old PAC-YT51CRB)

Product Overview

The PAC-YT53CRAU replaces the older model PAC-YT51CRB. It’s a wired remote controller that provides straightforward control over your unit’s operation mode, desired temperature, fan speed, and airflow direction. Up to 16 separate Mitsubishi mini split indoor units may be controlled by a single PAC-YT53CRAU, making it easy to manage multiple zones with similar temperature requirements.

Product Features

Internal Temperature Sensor: There is an air temperature sensor installed within the PAC YT53CRAU. Connected units may use this sensor instead of their own in applications where the unit’s return air sensor may not accurately reflect the temperature of the zone.

Package Includes: (1) Remote Controller Bottom Case, (1) Remote Controller Top Case, (2) M4x30 Roundhead Cross Slot Screws, (2) 4.1×16 Wood Screws

Compatible With: Mitsubishi mini split indoor units. *MSY-GE, MSZ-GE, and MFZ-KA mini split indoor units require a MAC-333IF-E system control interface to use this remote controller.
