ADVISORY High Motor
Temperature
Motor is operating
outside of pressure
flow curve. The system
is running at a lower
setpoint to preserve
motor life.
Run the system at a
lower duty cycle or with
a smaller mix chamber.
See performance charts in
system operation manual.
Manual override switch
on load center board is in
