Hi John, The data tag will have your full part # and serial #. The data tag is located either on the right hand side or left hand side of the heat pump near the base. If you could reply back to our email with your full model # and serial # this would help us determine which board you need. Also if you could email us a picture of the display that would help out as well. Are you looking at replacing the board or the board and the display?

My Model# is 075AHDSBNC and my SERIAL# is 1148741-F13 is this the correct Microprocessor Board?

We spoke with Aquacal and they confirmed that this is the correct Microprocessor Board for your model heat pump. If you need the display panel also then you would require the STA0062 Display Panel. I would suggest replacing the board first and if that doesn't fix your problem then replace the display panel.

Would this PCB work as a replacement for the AT12000A-A? Looks like it could work!

The STK0024 Replacement Board would be the correct replacement for the AT12000A-A.

I have a heat pump Model# 155ARDEBNB. Is this the correct replacement part for that model?

Hi BJ, The HP7R Microprocessor Board (ECP0005) will not work with you model because it's an older unit. You will need to get the AquaCal Upgrade Kit (STK0022).

Hi, James. This HP7R Microprocessor Board - ECS0287 is NOT compatible with your model. The Control Board Assembly - SMX306000016 is the correct part for your unit.

I have an aquacal heat pump 2001 model# 100ahdebna serial#1080141, the control board is bad and the # I found on the control board is EA200 10450906 on the back of the board, the HP7R control board looks similar. Is the HP7R the updated version of the control board for my unit?

Good Day Scott, Hope you are doing well the HP7R is the replacement for your unit, but you will also need a new control panel. The kit number to upgrade your unit is STK0178 which can be supplied by INYO pools. Thanks Robert Brown AquaCal Technical Support

I have an older AquaPro 800 AHNA heat pump, serial 13082 1145311. The control panel was not responding so I replaced it with a STA0062/ LBP0049 panel. My panel showed LBP0049 on the face and had an AquaPro sticker over the AquaCal name on the panel. I now get "CEr" fault code. Does this mean I get to replace the circuit board inside? It has P0349071744 on it.

Good Morning Mikie, Hope you are doing well. This ECP0005 (ECS0287) microprocessor board is fully compatible with the STA0062 control panel. This should take care of the CER code. Thanks, Robert Brown AquaCal Tech Support

I have a SQ175AHDSBTM pool heater. It appears to start normally, fan starts but the compressor never comes on. Just when you think the compressor should kick in the fan stops and the display goes blank. Then 888 is displayed, screen momentarily goes blank then 88 appears and the fan starts again. This looks just like a power up sequence. I want to replace control board. Supply voltage is 240 and voltage at control transformer is 28v. Do you think control board will fix this
