Nest Power Connector - not detected Nest Gen 3

mohonkjoey — Sun, 13 Mar 2022 00:37:18 GMT

I believe I have the power connectors correct, but they are not being detected when I go to settings on the Thermostat.

I can measure 25V at the thermostat.

does anyone know what the power measurements should be? One of mine show:

3.665V

VOC 33.69

VIN29.48

lin = 20 mA(i) <-- is this an issue?

You need to post a picture of how the original thermostat was wired and how you have wired the Nest products.

The two Grey wires (W and R) for the nest power connector are connected that are indicated in the first picture of my control panel. The C wire is connected to the 24V. The right side of the Next Power Connector (the white wire C and W) are connected as follows: C=T2 and W=A1

Is this for a multi-zone boiler system? What is the make and model number for it?

The "C" terminal is the common aka return for the 24VAC.

The thermostats for this system looks like they are just simple two-wire thermostat and they only provide a switch closer to the system.

I'm truly surprised that you haven't blown some fuses.

Yes, its a multi-zone boiler system. Make: System 2000 Energy Kinetics Mode: EK-1C.

Yes, I only have 2 wires for the thermostats.

No blown fuses yet! Thermostats function normally the way its connected in the pictures.

Did you ever figure out how the power connector is attached to your energy kinetics without a error code?

Hi everyone,

energykinetics, sorry for the delay.

A quick question: what message are you getting on your Nest Learning Thermostat?

Best,

Hey there,

I wanted to follow up and see if I could be of any help. If you are getting an N260 error, a C wire or Nest Power Connector is recommended for your thermostat. Please let me know if you have any questions from here, as I would be happy to take a closer look and assist you further.

Best regards,
Jake
