Product features
Zone Remote Controller is a remote controller designed to control Mitsubishi Electric’s air
conditioning units and zone controller.
Zone Remote Controller features such basic functions as operations and monitoring of air
conditioning units, zones, schedule-control functions and is equipped with three built-in sensors
(temperature, occupancy, brightness).
When the built-in occupancy sensor detects vacancy in a specific zone, the controller uses its
internal function to reduce energy-consumption.
