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.
▌Energy-save control with the use of the built-in occupancy sensor Occupancy sensor Brightness sensor • Energy-save control will be performed when the occupancy sensor detects vacancy. • When the occupancy sensor detects no human movement for a certain period of time, this will be regarded as the vacancy. • One of the following energy-save controls can be used at a time. Energy-save control mode Non-use Control when vacancy is detected – ON/OFF The unit will be turned off.
▌LED Indicator LED Indicator • The LED indicator indicates the operation status by lighting and blinking with different colors and brightness (High/Low), or by turning off. • Indicator colors: Blue, Light blue, Purple, Red, Pink, Orange, Yellow, Green, Lime, and White Operation status LED indicator The unit is in operation. Lights up in different colors according to the operation mode or the room temperature (three different levels). *1 The unit is stopped. Turns off. An error is occurring.
