Fault Codes 4 Star
LEDʼs and Status flash codes
The Red LED indicates the combustion fan is operating correctly and the pressure
switches have activated which then allows the ignition sequence to commence.
The Green LED will display the status of the heater controller. The LED flashes will be
of different duration times & patterns to indicate controller status.
LED patterns are divided into groups to aid the troubleshooting. Presence of LONG
pulse always indicates that the unit is in a lockout. The number of long pulses in an
LED pattern indicates the category of the lockout and the number of the following
short pulses in an LED pattern points to
the actual cause of a lockout.
Short pulses only indicate normal operation and non-lockout events or status.
1 LONG pulse followed by short pulses:
Lockouts caused by external switches and sensors (i.e.; thermistor, over temperature
switch, pressure switch or flame sensor).
2 LONG pulses followed by short pulses:
Lockouts caused by the controller hardware or by ignition, main valve, or modulation
valve.
3 LONG pulses followed by short pulses:
Lockouts caused by safe start faults or ground connection faults.
NOTE: 3 star status flash codes can be found on the product label.
