Fault Code F10
FLAME LOSS F10
The flame was lost while the unit was lit 3 times
during 1 demand call. The red fault light and the
word LOCKOUT flashing on the display indicate a
serious safety issue. The unit will not restart until
the technician repairs the cause of flame loss and
resets the unit. During this lockout fault, the pump
will be on as indicated on the bottom line of the
display.
1. Monitor gas pressure to the unit while in operation.
2. Assure that the flame is stable when lit.
3. Check to see if the display readout changes from “GAS
VALVE ON” to “RUN” within a few seconds after the boiler
ignites
4. Check the FLAME signal on the status display. It should be
above 1.0 when the unit is firing.
5. If the signal reads less than 1 microampere, clean the
flame rectifier and spark probe.
6. If the problem persists and the ‘FLAME” signal is still less
than 1.0, replace the flame probe and spark igniter probe.
7. The flame signal should be steady after the unit has been
firing for 1 minute and is normally at 5.0 to 9.0. If not steady,
disassemble the burner door and check the burner and its
sealing gaskets.
Fault Code F11
FALSE FLAME SIG F11
PUMP ON
There is flame when the control is not telling the
unit to run. The red fault light and the word
LOCKOUT flashing on the display indicate that this
code is serious safety issue. The unit will not restart
until a technician repairs the cause of the lockout
and resets the unit. During this lockout fault, the
pump will be on as indicated on the second line of
the display.
1. Look into window. If there is flame, turn the gas off to the
unit at the service valve and replace the gas valve.
2. If the flame signal on the status menu is greater than 1.0
when the burner is not lit, replace the spark igniter and the
flame rectification probe.
3. If the flame signal is not present after turning off the gas
supply, check the gas valve electrical connection.
4. Check for condensate backup. Repair the condensate
system as necessary. If condensate has partially filled the
combustion chamber, the refractory wall may be damaged
and should be replaced.
5. Turn the gas on at the service valve after corrective action
is taken.
Fault Code F13
FAN SPEED ERROR F13
PUMP ON
The fan speed had been more than 30% faster or
slower than the control commanded speed for more
than 10 seconds. The red fault light and flashing
LOCKOUT on the display indicates a serious safety
issue. The unit will not restart until the technician
repairs and resets the unit. During this lockout fault,
the pump will be on as indicated on the second line
of the display. 1. Check the combustion air fan wiring.
2. Measure the DC voltage from the red fan wire to ground
while it is connected to the fan. It should be between 24 to 40
volts. If it is lower than 24 volts, check for excessive external
loads connected to the sensor terminals. Disconnect the 5 pin
plug from the fan and check the voltage on the red wire
again. If it is now between 24-40 volts, replace the fan. If it is
still below 24 volts replace the boiler control board.
Fault Code F31
PROGRAM ERROR F31
There was an error while programming the control.
The cont
rol’s memory could be corrupt. The boiler
control will not function in this state and the pump
will be off. The only way to recover from this error is
to reprogram the control. If this error occurs at any
time other than when a technician is servicing the
unit, the control has failed and must be replaced.
Control must be reprogrammed. If reprogramming does not
solve problem, control must be replaced.
Fault Code PP
CONTROL PROGRAMED
PP
The control has been programmed by a technician
or the factory. After programming, the control was
left in a locked out mode. Press RESET to begin
use of the control. Press RESET for at least one second.
