OBSERVATION
Pump is making loud
noise
Note regarding excessive temperatures:
In order to protect the electronics from temperatures that are
dangerously high, the electronic control system monitors its own
temperature. If the measured temperature is too high the pump speed
is reduced. If the temperature rises above a safety limit, the pump will
shut itself off. The pump will automatically restart after cooling down.
