The past few months we have been having issues with our Carwash timing in our tunnel. The first half of the tunnel is always set correct but our second half of our tunnel is constantly having a timing issue. I can program the timing correctly in the RTC programming and leave for the day by the time I come back the next morning its off again but the same numbers are still programmed from the day before. We have replaced the ACE-84 Hydrapulse switch. I have spoke to RTC/ICS/CWS and have had no luck finding a solution. If anyone has my ideas or have ever had this issue any advice it would be greatly appreciated!
