Upgrading danfoss tpone-b to nest.

[Diav70]

Hi 

I want to upgrade 2 x tpone-b to nest.

I have 3 wires 

1. Connected to com 

2. Connected to NO (normally on) 

3. Not connected. 

Which would be the corresponding wires on the nest.

Hi Diav70,

Thanks for reaching out here in the Community. To know more about this issue, I’d like to confirm, where are you located? What type of heating or cooling or both systems do you have? What is the make and model of your HVAC system?

We'll wait for your update here.

Best,

Emerson
