2nd and 1st gen nest learning t-stat and 2 wire boiler

My house has 4 zones and they are all 2 wire with an oil boiler baseboard heat only system. I recently installed a 3rd gen learning  thermostat on one zone with no issues. I have a couple 2nd and first gen learning thermostats and before I try I was wondering if they are also compatible with a 2 wire system? I don’t feel like dealing with the power connector or running a c wire. Thank you in advance for any help.

Hi Bigblockf100,

 

Thanks for reaching out and for being a step ahead of us. I'm sorry for the delay. To confirm, in what country are you located? 

 

Best,
