Digital room thermostat with smart phone app

The Round Modulation Connected is a digital room thermostat connected to the Internet to control the Mark GS+. The thermostat is simple to operate by turning the adjusting ring. The clear digital display shows the set and actual temperature. A flame symbol indicates when the GS+ is operating. There is a reset button on the thermostat to enable resetting of the unit at any time.

Thanks to the optional Internet Gateway, the thermostat can also be accessed anytime, anywhere with a smart phone via the Total Connect Comfort app.
