4.3 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 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.
