Boiler Control Display
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 repre-
sent the fault code.
For a detailed description of the error codes, reference
the PRESTIGE 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 weath-
er appropriate safeguards or alarms should be
installed to prevent property damage.
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.
- 45ºF Boiler circulator is ON

at low fire.
- 50ºF Burner OFF and boiler circulator operates
for approximately 10 minutes.
