Soft Lockout Codes Displayed
F. Troubleshooting problems where a Soft Lockout Code is displayed.
When a soft lockout occurs, the
boiler will shut down, the display will turn red and the “Help” button will “blink”. Select the “blinking” “Help” button to
determine the cause of the soft lockout. The boiler will automatically restart once the condition that caused the lockout is
corrected.

Lockout
Number
Condition
Possible Cause
2
Boiler Safety Limit
Open
Boiler Safety Limit wired to terminals J6-1 or
3 OPEN:
•
External Limit.
• Optional LWCO
External Limit:
•
Water temperature is higher than External Limit setting. See “Hard
Lockout 4” for additional information.
• External device not used and jumper not installed.
• External Limit device is defective.
• Loose wiring to limit device
Optional Low Water Cut Off (LWCO)
• If yellow light on LWCO is on, system is low on water. Ensure air vent
is unobstructed and properly functioning as a blocked air vent can result
in low water indication.
• If neither yellow or green light on LWCO is on, check LWCO harness.

Boiler Safety Limit
Open
Blocked Flue/Inlet Switch wired to terminals
J5-1 OPEN
• Blocked Flue/Inlet Switch contact open - check for blocked flue/air intake.
NOTE
Blocked Flue/Inlet Switch Special Note
Before a call for heat the air pressure switch is closed. When there is a call
for heat with a blocked vent the air pressure switch will open (due to excessive
pressure of the blower against a blocked flue pipe) after the blower starts. The
control stops the start sequence and stops the blower. After the blower stops
the pressure switch re-closes and the cycle continues. The displays shows
the cause of trip for only the time the pressure switch is open.
