At this point the current configuration of the unit will be displayed for a few moments as shown below:
LED A
(red) on: the unit is configured as a heat pump;
LED B
(green) on: the unit is setup for a low wall application(factory default);
LED C
(yellow) on: the unit is setup for a low wall application;
LED D
(green) on: reset settings function after an active black-out (factory setting).
At this point all of the LEDs on the console will start flashing simultaneously for 10 seconds.
During this time the configuration of the unit can be changed by pressing the reset key (H) until the settings
match your specific application.
Configuration of the control board for a high wall installation sets an automatic correction of the
detected room temperature by 5.5ºF (-14.7ºC).
at this point the troubleshooting function activates the unit in heating mode (if it is a heat pump) for approx. 2
minutes and then in cooling mode for another 2 minutes. it is possible to terminate the function prematurely,
by simply by switching the unit off using the remote control.
Should the unit stop and signal an error, determine which LEDs are flashing then use the chart below to
determine the cause:

WARNINGS DISPLAYED DURING NORMAL OPERATION SHOULD NOT BE INTERPRETED AS ERRORS.
LED A: Indicates the filter may need cleaning.
After cleaning or replacing the filter the LED must be switched off manually as indicated in section 2.6.1
leD B steady light: indicates high coil temperature signal.
LED A + LED C flashing: Indicates continuous condensate pump operation.
