2) Confirm if the transformer power supply is normal. Measure transformer output end voltage:
no load AC24-28V, AC12-15V, AC15-18V.
Possible cause: the fuse inside the transformer is damaged; replace the
transformer(1000347562).
3) Record the software for the master control panel and manual controller again and observe if

4) Change to the spare manual controller for operation. If it operates normally, replace the
manual controller; if not so, replace the master control panel(1000391515).
