Trying to get the Nest Thermostat installed with the POWER CONNECTOR. I got a boiler, so heat only - requiring: C, W and R at the boiler control panel.
I can see W and R on my panel, but am confused about C, since there is C1 and C2. Also, can somebody confirm what's going on with the thermostat wire? The previous installer didn't use the thermostat connector T.
The thermostat is connected already, but not enough power, so the wifi and battery fail.
Thank you for your insight!

OnTech installer in partnership with Google just came to install, and he wasn't familiar with this board. The Nest Learning Thermostat is compatible with the wires already installed given the lower voltage. So, without installing the C-connector in anyway.
Seems with more information on this, I would have purchased the Learning version. That would be my recommendation.
Given that during the summer he does say I may need to charge it(pulls off easy) because it loses battery when its not used.
C1, C2 are not related to the needed Constant wire. I got the more expensive Learning Thermostat, which doesn't need the C wire. In the process of returning the items(C-connector and Thermostat) back to Google.
I only got the Rc and W1 wire connected, which were from the original(not Google) thermostat.
