lrh Posted January 9, 2021 Report Share Posted January 9, 2021 FLC code flashing I have just replaced the CTI circuit board and top controller on my pacific hot tub. Now flashing FLC code. The pressure sensor is not used. Pressure sensor pins J18 and J19 are connected to the flow sensor. There is nowhere to connect both sensors. There must be a simple ix for this as the old board was fine. I have emailed and called the Tech help at CTI many times. No reply. Circuit board #4-10-1503D59D. Top controller 1-628-S The hot tub works perfectly, just annoying. Can anybody help please? Quote Link to comment Share on other sites More sharing options...

I tried the programming but I must have missed a step. Following it again with more care solved the problem. 1 Quote Link to comment Share on other sites More sharing options...
