I have an Analogue Controller, What Do The Lights Mean?

The Analogue controller has many of the features and self-protection measures also seen in the digital controller. Using only LEDs it is more restricted in what information can be displayed to the user. 

The Analogue flow controller uses LEDs to display the following information:

Red Light - PS the pump pressure switch has activated

Blue Light - DE the control has detected a dead end

Green Light -  If the green light is solid, the battery voltage is 11V or lower.

If it is flashing, the battery voltage is 10.5V or lower. At this point, the pump will be shut down to protect the battery.

(Note. The analogue has smart battery management but can not display current voltage).
