Fantastic Brivis Thermostat Wiring Diagram Ideas - I'd positioned a pleasant 24v dpdt relay and a pleasant 24v 3pdt relay on the right mounting sockets and mount them to a din rail. This may make it smooth and easy. Placed it all in a field with the transformer and the packard and voila.
That is how i ended up connecting the nest thermostat. I did now not connect the c terminal to the transformer since the nest offers me an blunders "no energy to rc wire detected" if i do this. To date i haven't had any low battery troubles seeing that nest is capable of recharge itself from rc twine.
I wouldn't follow that advice via mr. Sun because of safety and it is overkill. You do not need the capability to power each high and low speeds at the identical time plus the 3pdt relay is not required for whatever, hold the dpdt. The same old approach is to apply a spdt touch to trade speeds so that voltage is handiest carried out to both the low or the high however by no means both. So the right manner is to have the dpdt relay (y1 first degree cooling) activate pump and the time postpone relay which controls strength through the commonplace leg of a 2d spdt relay. This second spdt relay is energized by way of the y2 for high velocity. Essentially what i am saying is that the original poster had the control common sense precisely accurate (except for r8222b1067 coil needs c) on his diagram and that it follows fashionable manage procedures and that i respectfully suggest to not observe the recommendation given later via mr. Solar. Nest has intelligence and would not care in case you terminate r or rc since it automatically will bounce these connectors. Your problem is two transformers. I suggest replacing the rc840t-120 with a second r822b1067. The transformer energy can be provided by using your present furnace transformer already related. You failed to show your heating wiring so i don't know if you had to use the c terminal currently or no longer. Many times you do not need the not unusual twine terminated at the nest. Wire the entirety such as you at the start show besides the r822b1067 coil goes to c not r.
