When configuring a Google Nest for a Ruud or Rheem heat pump…

When configuring a Google Nest for a Ruud or Rheem heat pump make sure to select the B reverse valve wiring option, not the default O which is also selected if you choose “I don’t know” during the initial Nest Equipment setup procedure. The Equipment options, including the heat pump configuration, can be found under Settings on the main Nest menu. Ruud and Rheem are the only brands who energize the reverse valve for heating, not cooling, the opposite of all other manufactures. “The guys at Century Supply (Rheem/Ruud dealer) say they are the only one’s who got it right.” Debatable and probably dependent on where you live. Is going without heat or cold air more important to you if the reverse valve failed?
