Hayward ProLogic Troubleshoot Manual

36
The ProLogic features a normally open circuit for each heater. When heat is called for,
based on the temp set point and water sensor, the low voltage contact will close; once
closed, the low voltage supplied by the heater (12-24VAC) should be returned to it.
On the display, verify that the Filter relay is activated
(denoted by an illuminated Filter LED). Also, verify the
main circulation pump is running. IF the pump is off and
cannot be turned on through the controller, go to
section 7. IF pump is running, proceed to step 6B.

On the local display, with the main circulation pump
running, verify the Heater LED is illuminated. IF the
heater LED is not illuminated, go to step 6C. IF the
heater LED is illuminated, proceed to step 6D to test
the heater relay.
Verify the heater LED is ON
