3 Wire Submersible Pump Wiring Diagram Lovely Nest Thermostat Wiring Diagram, Grp - I would not observe that advice by means of mr. Solar because of safety and it's overkill. You don't want the potential to electricity each excessive and coffee speeds at the identical time plus the 3pdt relay isn't required for anything, hold the dpdt. The usual method is to apply a spdt contact to alternate speeds in order that voltage is only applied to either the low or the excessive however never both. So the proper way is to have the dpdt relay (y1 first degree cooling) activate pump and the time put off relay which controls electricity through the not unusual leg of a 2nd spdt relay. This 2d spdt relay is energized through the y2 for excessive velocity. Basically what i'm saying is that the unique poster had the manipulate logic exactly accurate (except for r8222b1067 coil desires c) on his diagram and that it follows popular manipulate strategies and that i respectfully endorse to not observe the advice given later with the aid of mr. Solar. Nest has intelligence and doesn't care if you terminate r or rc since it mechanically will jump these connectors. Your trouble is two transformers. I advise replacing the rc840t-a hundred and twenty with a second r822b1067. The transformer strength can be supplied by using your existing furnace transformer already linked. You failed to show your heating wiring so i do not know if you had to use the c terminal presently or not. Regularly you do not need the not unusual twine terminated on the nest. Wire the whole lot such as you at first show except the r822b1067 coil goes to c no longer r.
