After all the wires are connected, re-attach your thermostat to its base. Turn the power for the system back on. After a few moments, use your thermostat to go to the Menu view Equipment , then check if the issue is resolved. 3.One possible solution for the rc wire nit providing power to your nest thermostat.

First, check to make sure that the RC wire is properly connected to the Nest base and that the other end is plugged into a wall outlet. If it is, then unplug the Nest base and plug it back in. This will sometimes reset the connection and restore power to the RC wire. If this doesn’t work, then you’ll need to check the wiring itself.Leave the Y wire on Y1 as is. Splice the other a/c wire (R) with one wire from the transformer. Measure voltage between Y1 and other wire from transformer. If you measure 48vac then swap the two transformer wires. Splice a short pigtail to the already spliced wires and connect to Rc. Take the other transformer wire and put on C.It is one Power Connector for each Nest thermostat. With your setup the R is where the three red wires connect under the blue wire nut. This feeds the thermostats. The C is where the two red wires connect to two white wires (right blue wire nut in your picture). This goes to #2 on the zone valves.What would make two Nest thermostats that work fine on the South system both claim no power on RC wire for the North system when there is power on RC wire tested via multimeter?

I'd find out what the c wire is connected to and then probably just connect it straight to the common side of the transformer.When both Rc and Rh are hooked up from different transformers, the internal control of the thermostat is still only programed to use the Rc terminal to power the thermostat. Therefore, you have to use the "C" wire from the cooling side to complete the circuit. The two transformers are separate independent circuits.Definitive answer: If Rc and Rh(or R) are separate (not shorted with the push up tab) then the common C must come from the AC transformer i.e. Rc and Cc power the thermostat. This is typical for a dual transformer system. If It is a single transformer system then Rc and Rh(or R) must be shorted (tab pushed upward to block Rc) and there is only one transformer therefore one C to choose from to ...

Similar to the RC wire, the RH wire is usually red and connects to the RH terminal on the control board. However, in some installations, the ...Poorly connected Rc and Rh wires. The Nest Thermostat separates the Rc and Rh wires. However, in some cases, you may only have one wire. This wire should go to the Rh port. If you are still getting a no power alert, try putting the red wire into the Rc port. Blown fuse in the air handler. Check if you have blown a fuse.If you just have one wire, regardless if it's labeled RC, it will go into the R terminal, and the jumper connecting terminals R and RC will be in place. Some thermostats have a jumper switch, some have a metal staple, others may have a plug, and the jumper may also just be a wire connecting the two terminals.The issue comes when I try to install the adapter. If I try to install the adapter, and place one wire into RC and one wire into C, the display on the Nest seems like everything is working (all wires are detected) and all of the wires have power - but nothing works when I "test" the system. The fan does not start up, nor does my AC or heat.I Purchased the Honeywell WiFi Prog Thermostat to replace my Round Digital Honeywell Thermostat.
