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.
