3.3 Temperature Monitoring
To avoid overheating of the system, the controller and motor temperatures are monitored online with an internal
sensor. If the controller temperature exceeds 70°C (158°F) or the motor temperature 90°C (194°F) for a
duration of more than 10 minutes, the system goes into an error state and the pump stops. At 80°C (176°F)
controller temperature or 100°C (212°F) motor temperature, the system stops immediately.
