The iComfort S30 now pairs with any Google Assistant device, a perfect addition to the already compatible Alexa and Siri devices. If This, Then That (IFTTT) can help program the iComfort thermostat around a homeowner’s schedule. It brings home automation apps together for the ultimate comfort experience. To display a more personalized custom backdrop, the new picture upload capability allows a personal photo to be uploaded via a smartphone and the iComfort App. The iComfort S30 ultra smart thermostat outperforms the rest by monitoring system operation in real time, with ventilation control the dealer gets alerted when it’s time for a filter change or repair, making sure the system always performs at its best and eliminating the need for a separate ventilation control panel.
