HVAC controller codes
Hello, After finall getting my HVAC to reset (probably due to a bad connection) it blinks out a code after completion. All dampers seem to work fine as well as zones. It blinks out code 15. Can anyone tell me what this might mean for a 1997 GC. In the event that I need to replace it can anyone tell me what these run new from a deaker for a dual zone system. Thanks.
