However, with out a g cord, nest will now not be able to control the fan independent of heating. Commonplace cord (c) not required in maximum cases, but strongly recommended. Use rh or rc in single transformer systems; no jumper cord required. For dual transformer structures, use rh for the heating transformer and rc for the cooling transformer.

But, without a g wire, nest will no longer be capable of control the fan impartial of heating. Not unusual twine (c) now not required in maximum cases, however strongly advocated. Use rh or rc in unmarried transformer structures; no jumper cord required. For dual transformer systems, use rh for the heating transformer and rc for the cooling transformer.
