Aquacal display contol unit

I have an aquacal heat pump 120AHDEWNB

S/N 1052685D05.  Circa 2004/2005. After a successful opening this year (complete with compressor start), the display goes blank after a few hours of running (but fan continues to run…cant tell if compressor is running as light is not displayed) If i pull power at the fuse/wait a few minutes and restart. All display features work and compressor starts after the waiting period…what can i do to fix/confirm it is running

Thank you for contacting Inyo. We’ve contacted our tech rep over at AquaCal. He’ll post back to this thread as soon as possible.

Good Morning Mr. Dionne,

Hope you are doing well. To be able to determine if the unit is still heating when the display goes blank, you will need to see if the unit is still ejecting cold air from above the fan. The air coming out the top should be 9-12 degrees colder than the ambient temperature. If the air is not colder, then your compressor is shutting down.

I believe the best way to fix this is to upgrade the control panel with kit # STK0178 which INYO pools can provide for you. Please feel free to contact our tech support department at 727-456-7411 with any questions.

Thanks,

Robert Brown
