No, your current thermostat uses line voltage (120 to 240Vac), and the Nest thermostat only supports 24Vac.

Hello folks,

I wanted to stop by and see how I could help.

Thanks for answering this thread, @Patrick_Caezza.

@Aladdinh, wire labels with the numbers 1, 2, 3, and 4 denote a private system. Typically, proprietary systems may only be used with thermostats produced by the same company. However, some proprietary systems could also allow the usage of cables from a normal heating system. Have a Nest expert examine your system to see if it can be rewired or stepdown the voltage to be Nest-compatible.

Feel free to let us know if you have more questions.
