I have a home with old radiators that are heated by a gas boiler, which has been set up for four zones—two downstairs and two upstairs. I'm looking to replace the old analog thermostats upstairs with something more modern, allowing me to program the temperature based on the time of day and day of the week. My goal is to heat the bedrooms at night and the other areas during the day. Just to clarify, the current thermostats control the radiators only, with two wires connected to them and a third wire coming from the wall that seems unnecessary. I'd love to know what options I have with this wiring. Is it worth installing smart thermostats, or would a programmable model suffice for my single system? Any recommendations for specific models that would fit my needs would be greatly appreciated! Thanks!

You should be good with almost any programmable thermostat. I've had a lot of success with the Honeywell TH4110U2005. It has an option to configure it specifically for hydronic heat, which eliminates cooling controls that you won't be using. Super simple to set up and program!
So you just connect the wires and that's all? Is it really that straightforward?
