Hey y’all, I can use some help. I have two used Nest 3gen’s that where given to me. They where both uninstalled because the facility upgraded to something else. Both worked great at the facility. I installed the first one and could not get the battery to hold a charge, so I moved to the second one. I charged it like the first one and installed it, after a few days it goes dead. It won’t take a charge. Technical information says I have Voc 40.17v and Vin40.17v, my batter is down to 3.628v. When I run the fan it seems to charge the battery, I didn’t run it long enough to prove that theory.
all my wires have 28v at the base. My new wiring setup is Y1, G, OB, RC, W2AUX, C.
My old wiring setup is the same as a above except with two extra jumpers E/AUX and RC/R. The other difference was a S1 and S2, both where for an outside temp sensor.
Remember both held a charge and where cycling the Hvac on an off at the other location.
I have a C wire, all wires have 28v’s, I charged the unit over night
any ideas?
