This enables the user to time and temperature control their heating up to 6 times per day, 7 days a week via a smartphone or tablet using Honeywell Home’s Total Connect Comfort App (Mobile Access Kit RFG100 sold separately).

The Honeywell Home Single Zone Thermostat can also be bound directly to an evohome Controller to allow Zone Temperature Sensing, Sensor Control for HR92 Radiator Controllers, Control of Single Zone Valve Operated Zones, Kickspace Heater Control, Single Zone Underfloor Heating Control and much more!
