To lock and unlock the remote control, press the
buttons simultaneously for about 3 seconds.
Resetting the Remote Control
If the remote control is not functioning properly, it can be reset by
pressing the reset button with a paper clip or tip of a pen. Current
settings will be cancelled and the control will return to the initial
settings and will be in standby mode. Push the ON/OFF button
to activate it.
Time Delay
If the On/Off button is pressed too soon after a stop, the
compressor will not start for 3 minutes due to the inherent
protection against frequent compressor cycling. The unit will only
emit an audible beep when the signals are received correctly.
Heating Features
If the unit is in the heating mode, there will be a delay when the
fan starts. The fan will start only after the coil is warmed up to
prevent cold blow.

Defrost Operation

In heating mode, if the outdoor coil is frosted, the indoor fan and
outdoor fan will turn off while system removes the frost on the
outdoor coil.
The system will automatically revert to normal operation when
frost is removed from the outdoor unit.
Auto Start
If the power fails while the unit is operating, the unit stores the
operating condition, and it will start operation automatically under
those conditions when the power is restored.
