Bryant 580G manual Control Board LED Alarms, II. Error Code Summary, IGC Board Error Code Summary

Table 12 Ð Control Board LED Alarms

LED	ERROR	DESCRIPTION	TROUBLESHOOTING
BLINKS	CODE		COMMENTS
1		Normal Operation	The control board ¯ashes the red LED in one-second intervals
			when the board is operating properly. Make sure DIP switch 3 is
			closed.
2	HF-13	Compressor 1 Safety	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.
3	HF-14	Compressor 2 Safety	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.
4	HF-15	Thermostat Failure	The thermostat is calling for both heating and cooling at the same
			time. The unit will operate on a ®rst call basis and will automati-
			cally reset.
5	HF-05	SAT Thermistor Failure	The supply-air temperature (SAT) sensor has failed. First check for
			wiring errors, then replace sensor.
6	HF-06	OAT Thermistor Failure	The outside-air temperature (OAT) sensor has failed. First check
			for wiring errors, then replace sensor.
7	HF-03	DIP Switch 2 is Open	Close DIP switch 2.
8	HF-12	DIP Switch 1 is Open	Close DIP switch 1.
9	SE-05	Loss of Communications	Communications between the expansion board and the control
		with Expansion Board	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.
10	HF-16	Control Board Failure	Generated when hardware has failed on control board. Replace
			the control board.
11	HF-17	Expansion Board Failure	Generated when hardware has failed on the expansion board.
			Replace the expansion board.

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.
