Just replaced Nest Gen 2 with Gen 4 (have heat pump). Copied wiring
setup used in Gen 2, but it's heating when on cooling. How do we fix
this?Y1, G, OB, RC, Y2 Aux, C
Resolved: Found suggestion to go to Settings - Equipment - Heat Pump and
switch from O to B (or vice versa) via the Home app. That seems to be
working.
