My home was built in 2001 and has 2 heating zones, no cooling. The floor 1 thermostat is digital and has just two wires - Rh and W. The floor 2 thermostat is analog, and also has two wires. I would like to install Nest Thermostats on both floors.
I need help understanding how and where to install my Nest Power Connector in my home. My boiler control board does NOT have a C terminal I can use, so I am happy to purchase an external 24V transformer like this one.
My main road-block is placing it correctly so that it powers both thermostats in my home. I do not understand at all how my two zones are configured, but I can see where all the wires go and I'm confident I could complete the install if I could just get someone with some expertise to tell me what is what.
Here is a link to pictures of the two control boards on my boiler as well as a mysterious 3rd component that appears to splice together 4 different 24V wires. Can you help me make sense of this? Thank you!
