Will this work with a steam boiler heating system?? null

Hi Kesha! The Honeywell Lyric T5 Wi-Fi thermostat Dark Grey is compatible with steam boiler systems. However you will want to confirm that you have a common 24V wire to power the the device. If you have any questions with installation please feel free to contact Honeywell technical Support at (800) 633-3991. Thank you.

Unfortunately, the documentation specifically states that it does NOT support a steam boiler heating system.
