The free Totaline EZ3 Wi-Fi® Thermostat App is designed to utilize smart phone swipe/scroll/touch technology to provide easy to use programming for the EZ3 Wi-Fi® Thermostat in homes or businesses. It utilizes vibrant colors with easy to understand icons and gives complete control of the operation of the heating and cooling system from anywhere you have Wi-Fi® connectivity. With this powerful app, you can easily review thermostat settings and adjust programming as desired and the screens of the EZ3 APP mirror those of the actual EZ3 Wi-Fi® Thermostat, so it is extremely easy to use. There are also 'alert notifications' sent to the app if issues are detected such as filter replacement reminders. The installing dealer's information is provided to make it easy to contact them for service if needed.
