Appliance Control Display
Error (Hard Lockout) Mode
If a system fault occurs, the system enters a hard
lockout condition which requires a manual reset by
pressing the RESET button
.
A hard lock is indi-
cated by a flashing [E] on the operating display as
well as a flashing LED light above the reset but-
ton. The error code is located on the main display.
The error must be corrected before the control will
reset.
The appliance freeze protection feature is
disabled during a Hard Lockout, however
the CH circulator will operate.
During a hard lockout or low water condition
the appliance will not re-start without serv-
ice. If the heating system is left unattended in
cold weather appropriate safeguards or
alarms should be installed to prevent proper-
ty damage.
