The Balboa BP System has a feature that provides reminder messages which appear on the Topside display. The reminder messages are generated by an internal timer that tracks how long the Control Pack has been powered on.
The system does not actually have the ability to check the pH, filter condition, water chemistry, etc. The message will appear regardless of the actual condition because it is solely prompted by the timer.
It is a good practice to perform the displayed task in order to ensure that your spa is always balanced and maintained correctly. If you are certain that the task does not need to be performed, simply press either the Temp Up or Temp Down button to dismiss the message. Another message may appear), but once you have performed the task, you can dismiss this as well.
