Product features
Smart ME controller is a remote controller designed to control Mitsubishi
Electric’s air conditioning units and also allows for the control of other
manufacturer’s products connected via Mitsubishi Electric’s AHC. It can
control up to sixteen indoor units and one AHC. Smart ME controller features
such basic functions as operations and monitoring of air conditioning units
and schedule-control functions and is equipped with four built-in sensors
(temperature, humidity, occupancy, brightness), which enable an integrated
control of the system, including the humidifiers and ventilation units
connected to the system via AHC, to help create comfortable environment. When
the built-in occupancy sensor detects vacancy in a specific zone, the
controller uses its internal function to reduce energy-consumption.

Basic operations
Auto (dual set point) and Setback modes:
When the operation mode is set to the Auto (dual set point) mode or the
Setback mode, two set temperatures (one each for cooling and heating) can be
set. Depending on the room temperature, indoor unit will automatically operate
in either the cooling or heating mode and keep the room temperature within the
preset range.
Differences between the two modes
· Auto (dual set point) mode The set temperatures that are specified for the
Cool/Drying mode and the Heat mode will be used to automatically control the
room temperature to stay within the set temperatures. This mode is especially
effective during the in-between seasons, when the temperature difference
between the highest and the lowest is large and both heating and cooling modes
are used within the same day.

· Setback mode Room temperature is controlled to stay within the set temperature range that is specified for the Setback mode. By leaving sufficient temperature differential between the set temperature for cooling (upper limit) and heating (lower limit), it is possible to keep the room temperature within the specified range without overworking the air conditioners. This setting will be especially effective during periods of non- occupancy.
