Re: York Chiller problems
His Model No. may not be correct, YSCA CA50FB.
I think he has a YS, not a YCAS. At any rate, he has one of the following issues.
1) Comm wiring issue to the microboard that he just replaced.
2) Jumpers on microboard not set up properly.
I assume that all is well with his MicroGateway to the BAS, since he only disconnect the Comm line to microboard. He will have to change his control on panel from Local to Remote (if single line panel), or to ISN (if Optiview), if he wants to start/stop, and control setpoints via BAS.
