Hi Pablo,
JTV2 He bottom fill would not work in PLC mode this morning. It would work in key switch manual mode.
In Auto mode, the valve would open but would not close.
While trouble shooting found the br/wh and or/wh wires were swapped on one side of PLC-TS-05 #2 and#3.
Swapped them back and the valve is now working properly.
All valves had been tested and worked properly previously, both in auto mode and in manual mode. Not sure how this happen, has anyone been working on wiring in the upper part of the rack? Heidi only worked on terminal strip MAG-TS-02 to recover the temperatures sensors.
Whit may have photos
Steven
