0
E2PROM_READ_ERROR
Internal software error
Replace the power control
board
1
IGNIT_ERROR
Three unsuccessful ignition
attempts in a row
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- 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.
2
GV_RELAY_ERROR
Failure detected in the GV
(Gas Valve) relay
a- Check the integrity of the
wire connections between
gas valve and control board.
a- If wires are damaged,
replace them
b- If wires are ok, replace
the gas
valve or the power control
board.
3
SAFETY_RELAY_ERROR
Failure detected in the
Safety relay
Replace the power control
board
4
BLOCKING_TOO_LONG
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.
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).
Remove the cause of the
Blocking
error
5
FAN_ERROR_NOT_RUNNING
Fan is not running for more
than 60 seconds.
a- Check for 120 VAC power
connection of the fan.
b- Check PWM connection of
the fan.
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.
6
FAN_ERROR_TOO_SLOW
Fan runs too slow for more
than 60 seconds
7
FAN_ERROR_TOO_FAST
Fan runs too fast for more
than 60 seconds
8
RAM_ERROR
Internal software error
Replace the power control
board
9
WRONG_EEPROM_SIGNATURE
Contents of E2PROM is not up
to date
Replace the power control
board
10
E2PROM_ERROR
Wrong safety parameters in
E2PROM
Replace the power control
board
11
STATE_ERROR
Internal software error
Replace the power control
board
12
ROM_ERROR
Internal software error
Replace the power control
board
