Full disclosure: I am not an HVAC technician or service person, just a homeowner. Thunderstorm fried the control board on my Rheem/Ruud 5-ton unit. Board has been replaced, but the clowns that installed the unit originally 3 years ago ran off with the memory card needed to load the board with the correct settings. Replacement card will take 7-10 days to ship. I'm in Houston and A/C is almost mandatory now. Is there any safe way to turn on the A/C manually (via the DIP switches or other "hack") until the memory card arrives? Thanks in advance for your help.
Additions: I have found the system information. If I am reading this info correctly from the manuals and receipts, the memory card part number is XXXXX and the unit is Rheem FG RGPE-10EBRMR. Hope that helps.
