5 FLASH:This fault is indicated if the normally closed con-
tacts in the rollout switch opens. The rollout control is manu-
ally reset. If it has opened, check for proper combustion air,
proper inducer operation, primary heat exchanger failure or
burner problem. Be sure to reset the switch after correcting
the failure condition.
6 FLASH: This indicates that after the unit was operating, the
pressure switch opened 4 times during the call for heat. If the
main blower is in a "Delay on" mode it will complete it, and
any subsequent delay off period. The ventor continues to
operate until the pressure switch re-closes or a call for heat is
removed.
7 FLASH: This fault code indicates that the flame could not
be established. This no-light condition occurred 3 times (3
retries) during the call for heat before locking out. This may
be caused by low gas pressure, faulty gas valve, faulty hot
surface ignitor or burner problem.
8 FLASH: This fault is indicated if the flame is lost 5 times (5
recycles) during the heating cycle. This could be caused by
low gas pressure or faulty gas valve.
9 FLASH: Indicates reversed line voltage polarity. Both heat-
ing and cooling operations will be affected. Check polarity at
furnace and branch.
11 FLASH: This fault will be indicated if the rollout jumper
wire connection soldered into the board, is broken. If this fault
occurs the control will have to be replaced.
STEADY ON: This fault occurs if the gas valve is energized
when there is no call for heat. If this happens the ventor is
energized and will remain energized for 5 seconds or until the
fault clears itself at which point the ventor de-energizes. This
failure is counted as a recycle. Check the gas valve and con-
trol for proper operation.
60 MINUTE AUTOMATIC RESET FROM LOCKOUT: This
control includes a "watchdog" type circuit that will reset from
a lockout condition after 60 minutes. Operational faults
1,6,7,8 and Steady On will be reset. This provides protection
to an unoccupied structure if a temporary condition exists
causing a furnace malfunction. An example would be a low
incoming gas supply pressure preventing unit operation.
When the gas pressure is restored, at some point the "watch-
dog" would restart the unit and provide heat for the house.
NOTE: If a flame is detected the control flashes the LED for
1/8 of a second and then enters a flame stabilization period.
.
Never jump pressure switch to allow furnace oper-
ation. To do so will allow furnace to operate under
potentially hazardous conditions.
Do not try to repair controls. Replace defective
controls with UPG Source 1 Parts.
Never adjust pressure switch to allow furnace
operation.
