Looking for subfloor heating thermostat that works in North America


I’m looking for a thermostat to control subfloor heating (240V) for my home in Canada.
I see the Heat-It thermostat that can connect to a floor sensor and communicate via z-wave. From what this device is for Europe and operates on 230V.

Can someone recommend a similar thermostat for North America (connects to subfloor sensor, operates on 240V) that binds with OpenHAB?
