SYMPTOM:
Pump contactor opens
and closes, then can
only be closed by
opening and closing the

POSSIBLE CAUSE:
Discharged battery
•
=
Check battery to insure
proper state of charge.
Loose connection at P1.

Controller
SYMPTOM:
Reduced or no power to pump motor in
control range.
POSSIBLE CAUSE:
Control is in thermal cut-back.
•
=
Allow control to cool, status code
should disappear.
•
=
If control cools to ambient
temperature and the fault remains
when the control is restarted, replace
the control.
