Please note system will NOT run normally unless one of the following procedures is completed.
When the system is first powered up, the indoor and outdoor LED display will display “CC”. Please note that this is NOT
an error code. This is an indicator that the system is ready to run the “Preprogrammed System Test”.
The installer can choose one of the two following options:
• Option 1
(Preprogrammed System Test):
– Set the indoor mode to “Heat” or “Cool” and then set the indoor temperature to 77°F (25°C). The preprogrammed
system test will start within five seconds.
• The indoor display will flash “Fn” and “N1”; the outdoor display will flash “N1”.
• The test will continue to run for 18~25 mins, including heating test (display “N2”) and cooling test (display “N3”)
depending on outdoor conditions. For sequence of operation, refer to Installation Manual Section “Energy Star
Models (Installation Capabilities)”.
• Upon completion and passing of all tests, the indoor and outdoor display will show “PS”.
– User can press any button to exit the test mode. The system can now be used normally.
• Option 2
(bypass “Preprogramed System Test”): set the indoor mode to “Dry” mode first and then set the indoor
temperature to 68°F (20°C).
• The indoor display will flash “BP” for five seconds and shut down automatically.
• The system can now be used normally.
Note:
The automatic tests can also be by-passed by
setting the indoor mode to dry and then setting the temperature
to 68°F (20°C)
while the unit is flashing CC after initial power has been applied to the unit. The indoor display should
read BP for 5 seconds then go into stand-by mode. The unit can then be used normally. If installation test mode has been
started, it will not be able to by-pass the test unless the power has been recycled prior to finishing the installation tests.
Note:
If the outdoor temperature is exceeding normal operation range, (eg. below -4°F (-20°C) or above 115°F(46°C)),
running pre-programmable test may result in error code. Manufacturer suggests to by-pass the test during the severe
weather and go back to the jobsite and run the test when outdoor temperature permits.
Note:
If there is a need to run the pre-programmed installation tests again after successfully completing them initially, set
the remote controller to cool, high fan speed, 60°F (16°C), and then press the sleep button 4 times continuously. After
hearing 5 beeps on the indoor unit, power cycle
.
Note:
In order to achieve maximum performance at low ambient conditions it is recommend to set fan speed to turbo.
