Start-Up Procedures
Error (Hard Lockout) Mode
If a system fault occurs while the appliance 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 give the code for this
fault.
For a detailed description of the error codes,
reference the MODULATING DELTA
Troubleshooting Guide.
The freeze protection feature is disabled
during a Hard Lockout.
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.
An optional control/interface is available
from Triangle Tube which will provide a
set of alarm contact which will close dur-
ing a hard lockout.
