Error (Hard Lockout) Mode
If a system fault occurs while the boiler is
running, the system goes into lockout and
the display starts to flash with the first digit
as an E and the next two digits represent the
fault code.
For a detailed description of the error codes,
reference the Esteem Trouble Shooting
Guide.
WARNING!
DURING A HARD LOCKOUT OR LOW WATER
CONDITION THE BOILER WILL NOT RE-START
WITHOUT SERVICE. IF THE HEATING SYSTEM
IS LEFT UNATTENDED IN COLD WEATHER, AP-
PROPRIATE SAFEGUARDS OR ALARMS SHOULD
BE INSTALLED TO PREVENT PROPERTY DAM-
AGE.
Boiler Freeze Protection Feature
The boiler control has a freeze protection
feature built in. This feature monitors the
boiler temperature and responds as follows
when no call for heat is present.
• 46ºF Boiler circulator is ON
• 38ºF Boiler circulator is ON and burner
operates at low fire.
• 50ºF Burner OFF and boiler circulator
operates for approximately 10 minutes.
CAUTION
The boiler freeze protection feature is
disabled during a Hard Lockout, how-
ever the CH circulator will operate.
CAUTION
During a hard lockout or low water con-
dition the boiler will not re-start without
service. If the heating system is left un-
attended in cold weather, appropriate
safeguards or alarms should be installed
to prevent property damage.
