Simple up and down buttons and a display with large type make this thermostat easy to read and use. A Slab Sensor 079 is included to measure floor temperature to protect the floor from overheating and enhance comfort.

An optional Adaptor Plate 012 is available which allows the thermostat to be installed onto a single gang electrical box.
