I recently installed a 3rd gen learning &nbsp;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.</P> Tue, 28 Nov 2023 21:36:35 GMT https://www.googlenestcommunity.com/t5/Nest-Thermostats/2nd-and-1st-gen-nest-learning-t-stat-and-2-wire-boiler/m-p/552830#M110369 Bigblockf100 2023-11-28T21:36:35Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/2nd-and-1st-gen-nest-learning-t-stat-and-2-wire-boiler/m-p/555184#M110909 <P>Hi&nbsp;<A href="https://goo.gle/46GyqgK" target="_blank">Bigblockf100</A>,</P> <P>&nbsp;</P> <P>Thanks for reaching out and for being a step ahead of us.
