description
This alarm indicates that the controller
has detected a failure in its nonvolatile
memory (this is where all of the controller's
configuration and calibration settings are
stored). This indicates an internal problem
and the HTC should be replaced and
returned to Pentair Thermal Managament
for repair.
This alarm indicates that the number of off-
to-on transitions of a contactor has exceeded
the CONTACTOR COUNT ALARM setting and
needs to be replaced.

Cause of alarm
• The HTC cannot bypass the failed area of its memory
and has loaded factory defaults into this failed area.
• Contactor may be worn.
• Some configuration parameter (i.e. DEADBAND, AUTO
CYCLE INTERVAL, load shedding etc.) is causing the
contactor to toggle more than usual.
