Pentair Minimax NT HI on display
My Minimax NT just displayed HI on the led display. After reading through the manual it appears that one of my HI-Limit thermostats are acting up. My pool water on temps out at 70 degrees!
I was wondering if one can bypass the Hi-limit thermostats as a way to figure out which one is bad. I actually tried doing this one at a time and I still had HI on the display after powering back up. I did remove each Hi-Limit thermostat to check for mineral build-up. Neither one was exceptionally dirty. I did brush them both off and reinstalled them. Still no luck.
Is there any other source for the HI code on the display or am I on the right track and replacing both Hi-Limit thermostats should solve the problem?
