Thermal Management
3.1. Temperature Monitoring
Temperatures of the Controller and of the Pump are continuously monitored with internal sensors to ensure safety
of user and equipment. If the Controller temperature ever reaches 80 C, the controller will report an alarm and
shut off pump operation. Pump will not restart automatically once the controller has cooled. A warning will be
provided if the controller reaches a temperature of 55 degrees C.
If the pump internal temperature reaches 110 degrees C, the controller will report a warning, but the pump
operation will remain unchanged. The user may clear a warning once the pump temperature has cooled to 105
degrees C without stopping the pump. Once the pump reaches 110 degrees C, the controller will start to throttle
down power to maintain pump temperature from climbing higher. If the pump temperature reaches 120 degrees
C, controller will report an alarm and shut off pump operation. The pump will not restart automatically once
temperature is in acceptable range.
