Hey guys having a few probs with a York YCAL0253.
System 1 is faulting on mp/hpco inhibit.
I have no manual for help & called johnston controls.
Tested 3x comp on system 1 motor protection, all were pulling 0.1ohms. I also pressed the resets on both hp switches, but they hadn't tripped, he told me there may be a factory fault with the secondary hp switch on system 1 but chiller has been running for years now. The millenium controller has the chiller running on r22, when in fact it's actually on r407c. The johnston controls guy didn't know how to change it back to r407c, said he'd call me back but hasn't! Am I right in thinking that this may cause the chiller to run erratically? system 2 is tripping on LP also when I eventually got it running due to no cool load.

Hi, see the manual (link from install monkey)
