Help Please... I need help calibrating a circuit board

[Tony Duprey]

I just installed a My Tech PH 111A circuit board in my pool heater. The heater does work now; but, the readout on the heater shows an incorrect reading for "Current Water Temp". There are three posts that I could turn ( I think they are
potentiometers );but no information about how to adjust them--or which one-- inorder to get the correct temp reading on the window. Anyone have any information...it would be greatly appreciated.

Tony, Have you tired calling the company? Ask to talk to a tech in the back. That should get you an answer. If that does not work let me know. I will ping someone who might know.
