Troubleshooting HEVAC faults
The faultmate pulled the following HEVAC codes the other day:
b1a61
b1b74
b1b75
b1b76
b1b77
Any idea on how to troubleshoot these? The strangest behavior seems to be that sometimes zone selection doesnt work very well, but can't say for sure.
Thanks.

A fair brace of codes. Start with a code reset and see what comes back. Then try a HEVAC reset and take it from there.
