Floor sensors are a great add-on for in-floor hydronic radiant heating systems. Installed directly in the slab or in a conduit, the sensors can be connected to compatible thermostats to establish high and low limits for the surface temperature, which take precedence over the room air setting. Use floor sensors to protect wood flooring, prevent rooms with dual heat sources from overheating, and to make the floor comfortable for small children or pets.
