Start-Up Procedures
Error (Hard Lockout) Mode
If a system fault occurs, the system enters a
hard lockout condition which requires a manu-
al reset by pressing the RESET button . A
hard lock is indicated by a flashing [E] on the
operating display as well as a flashing LED
light above the reset button. 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, how-
ever the CH circulator will operate.
During a hard lockout or low water con-
dition the appliance will not re-start
without service. If the heating system is
left unattended in cold weather appro-
priate safeguards or alarms should be
installed to prevent property damage.
