3.3 Temperature Monitoring
To avoid overheating of the system, the controller and motor temperatures are monitored. If the controller
temperature exceeds 70 °C (158 °F) or the motor temperature exceeds 90 °C (194 °F) for 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.
