A rotary-dial thermostat for radiant floor and hydronic heating — the systems where a standard forced-air thermostat won't do the job. Programmable schedules, app control, and a knob that still works when your phone is upstairs.
- Three versions — electric floor heating, water heating, or gas boiler
- Physical knob — adjust without the app
- Programmable schedules — different temperatures by time and day
- App control — Tuya / Smart Life
- Works with Alexa and Google Home
Check your system before ordering. This is for radiant floor and hydronic heating, not standard US forced-air HVAC. If your current thermostat runs on 24V low-voltage wiring to a furnace, this is not the right controller — email us and we'll tell you what is.
