LOU Fault Code: 24 Volt Power Supply is Damaged

Postby HTP » Wed May 30, 2012 1:23 pm

This display indicates that the 24 volt power supply on the control is damaged or overloaded. This code resets automatically if it is the result of an overload and that overload condition is removed. The second line indicates the status of the pump. Note that while 24 volt power is low, the pump output will be on.
