II. ERROR CODE SUMMARY
A summary of the error codes is listed in Table 13. If more
than one error code exists, they will be displayed on the LED
of the IGC board in sequence. Fault history is deleted when
power is turned off.

TROUBLESHOOTING
The control board flashes the red LED in one-second intervals
when the board is operating properly. Make sure DIP switch 3 is
closed.
The high or low pressure safety switch for compressor no. 1 has
opened for 3 seconds. The error will be cleared and compressor
no. 1 will be allowed to turn on in 15 minutes. If the safeties have
been tripped 3 times in 90 minutes, compressor no. 1 will be
locked out until the control board has been manually reset.
The high or low pressure safety switch for compressor no. 2 has
opened for 3 seconds. The error will be cleared and compressor
no. 2 will be allowed to turn on in 15 minutes. If the safeties have
been tripped 3 times in 90 minutes, compressor no. 2 will be
locked out until the control board has been manually reset.
The thermostat is calling for both heating and cooling at the same
time. The unit will operate on a first call basis and will automati-
cally reset.
The supply-air temperature (SAT) sensor has failed. First check for
wiring errors, then replace sensor.
The outside-air temperature (OAT) sensor has failed. First check
for wiring errors, then replace sensor.
Close DIP switch 2.
Close DIP switch 1.
Communications between the expansion board and the control
board have been interrupted. Ensure that an expansion board
is installed and wired using the wire harness supplied with the
expansion module. If an expansion board is not used, ensure that
DIP switch position 3 is in the closed position and reset power.
Generated when hardware has failed on control board. Replace
the control board.
Generated when hardware has failed on the expansion board.
Replace the expansion board.
