Fault Fault
Category Description
Fuel/Air Burner load
maximum
threshold
Detailed Description
During curve commissioning,
the S1 threshold is hard-
coded at 6000. If S1 rises
above 6000, this fault occurs,
but does not cause a lockout.
During normal run mode, the
S1 threshold is programmed
as Y (or at least 25 counts)
above the S1 maximum
commissioned Installer
Correction Curve value.
Y is programmed in the OEM
Setup parameters via the
S1 maximum threshold (%)
parameter. The default is
120%.
Remediation Steps
1.) Check that air duct is clear free of any
foreign bodies and pollution.
2.) Check that blower is running at a
proper rate.
3.) Check Fuel/Air Module signal
connections for proper engagement.
4.) Reset valve and burner management
system.
5.) Recommission Fuel/Air curve.
6.) If fault persists, replace Fuel/Air
Module.
7.) Reset valve and burner management
system.
8.) Accept new Fuel/Air Ratio Module on
the FARMOD tab in the Setup & Tests
menu of user interface.
9.) Recommission partially or fully as
desired.
10.) Reset valve and burner management
system, monitoring for proper operation.
