Description
Internal software error
Three unsuccessful ignition
attempts in a row
Failure detected in the GV
(Gas Valve) relay
Failure detected in the
Safety relay
Control had a blocking error
for more than 20 hours.
This error is caused when
any of the Blocking errors
have occurred and wasn't
corrected automatically.
Therefore it causes a Locking
error.
Fan is not running for more
than 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 is not up
to date
Wrong safety parameters in
E2PROM

Checks
a- Check gas supply
pressure;
b- Check spark and ignitor
rod.
c- Correct amount of air;
d-Check for 120VAC at the gas
valve.
e- Ensure that the gas valve
is functioning properly by
checking for changes in gas
pressure.
a- Check the integrity of the
wire connections between
gas valve and control board.
a- Press RESET button to
display the Blocking error
description
b- Check error log on
touchscreen.
c- The blocking error that
occurred previous to current
locking error will be the
cause (i.e.- 163 LowExFlow).
a- Check for 120 VAC power
connection of the fan.
b- Check PWM connection of
the fan.
SHUTDOWN APPENDIX
Solutions
Replace the power control
board
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.
Replace the power control
board
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, replace power
control board;
c- Replace the fan.
