If the MEMORY Function is not set, the system will need to be turned ON when power is
restored, and all settings will be at factory defaults.
While your Indoor Unit is turned OFF, press the MODE and buttons simultaneously for 5 seconds to turn the
MEMORY mode ON. Repeating this will turn MEMORY mode OFF. MEMORY is turned off by default.
ERRORS
If a system protection or an error or malfunction occurs during operation, a code will be shown on the LED
display.If multiple errors occur at the same time, the LED display will cycle through the codes on the display.In
the event of any error, shut down the unit and contact your installer or an HVAC professional near you.
NOTICE
Each Wall Mount Control is wired to a single Indoor Unit.
Recessed Fan Coild and Universal Air Handler Indoor Units that do not have an IR receiver built-in, can be
controlled with one of these options:
•
Wall Mount Control
•
Remote-Wall Mount Control
•
Thermostat-YMGI Bridge Controller-Wall Mount Control
Wall Mounted EW, Ceiling Cassette EC, Floor/Ceiling Mount EU Indoor Units which have an IR receiver built
in, and can be controlled with a Remote Control or the options listed above.
