Also make sure to pre-charge the Nest so that the battery is at 100% before wiring to the ZVC or SR controls.0

Do the Taco ZVCs apply power to close the valves, or are they assumed to be self-closing? Said differently, does the Nest connect power from Rh to W1and C respectively when calling and not calling for heat?0
