ADDITIONAL THINGS YOU SHOULD KNOW
Now that you understand the basic operation functions, here are more control features with which you should become
familiar.
The “cool” circuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents
overheating of the compressor and possible circuit breaker tripping. The fan will continue to run during this time.
The control will maintain the set temperature within 1 degree Celsius, between 16 °C and 32 °C(60 °F and 90 °F) .
The control is capable of displaying temperature in degrees Fahrenheit or degrees Celsius. To convert from one to the
other and back, press and hold both the “TEMP/TIMER” Up( ) and Down ( ) buttons for 3 seconds.
FAULT CODES :
If the display reads “ES” or “AS”, a sensor has failed. Contact 1-800-4-MY-HOME® for repair.
AUTO RE-START :
After a power outage, the unit will remember the last setting and return the unit to the same setting once power is restored.

There is a 2-Second delay for the compressor shutting down when selecting FAN ONLY. This is to cover the possibility
of having to roll through to select another mode.
