DESCRIPTION OF STATUS
STATUS CODE
Open thermal protector (TP1) or
-141
transistor is over temperature.
MEMORY RECALL
NO
SYMPTOM:
Circuits valid
Reduced or no power to pump motor in
for
control range.
Pump
Controller
POSSIBLE CAUSE:
Control is in thermal cut-back.
•=Allow control to cool, status code
should disappear.
•=
