Description
Internal software error
Three unsuccessful ignition attempts in
a row
Failure detected in the GV (Gas Valve) relay a- Check the integrity of the
Internal control board error
Control had a blocking error for more
than 20 hours.
This error is caused when any Blocking
errors occur and are not corrected auto-
matically.
Fan is not running after 60 seconds.
Fan runs too slow for more than 60
seconds
Fan runs too fast for more than 60
seconds
Internal software error
Contents of E2PROM are not up to date
Wrong safety parameters in E2PROM
Internal software error
Internal software error
Air pressure switch not working
Air pressure switch not working
The external overheat protection is en-
abled or the High limit sensor measures a
temperature of over 95°C (203°F))
Internal software error
Internal software error
Internal software error
Flame still present 10 seconds after clos-
ing the gas valve
Flame is detected before ignition
Three flame failures during one demand
cycle
Error code RAM byte was corrupted to an
unknown error code
Checks
a- Check gas supply pressure;
b- Check ignition spark;
c- Correct amount of air;
d-Check for120VAC at the gas valve.

description
a- Check for 120 VAC power con-
nection of the fan.
b- Check PWM connection of the
fan.
a- Check the pump to verify the
flow circulation;
b- Check if the valves on hydraulic
circuit are open;
c- Check the high limit switch.
a- Check the integrity of the wire
connections of the spark and the
earth on heat exchanger
b- check ionization signal while
running

RECYCLING AND DISPOSAL APPENDIX
Solutions
Control board replacement
a- If the gas supply pressure is
incorrect, it must be adjusted to the
correct pressure;
b- If spark is not present check for
correct ignition electrode position;
c- If the combustion air pressure is
incorrect, inspect the vent system
and eliminate any obstructions;
d- If the voltage to the gas valve is
not 120Vac the power control board
must be replaced.
a- If wires are damaged, replace
them
b- If wires are ok, replace the gas
valve or the power control board.
Control board replacement
Remove the cause of the Blocking
error
a- If no 120 VAC voltage is present,
replace the power control board;
b- If no PWM signal is present, re-
place power control board;
c- Replace the fan.
