5/5

Best feature of my new HVAC System

November 16, 2012

The iComfort Wi-Fi touchscreen is really a great feature. Setting the heating/ac scheduling comes with easy controls. With our busy schedules I can easily change the settings when our schedules change. Why heat the house when we are not there?? I can easily change the settings from my smartphone. I would recommend this product to anyone that is installing any new HVAC system or even add it to your existing system. I am truly amazed at the features and capabilities.

Yes, I recommend this product.

S40 WiFi Thermostat

September 19, 2026

Our original Icomfort WiFi thermostat had a screen fail after only 9 years and is discontinued. We upgraded to an S40 and I like its features however the indoor humidity was 19% high. Ive had the contractore out and he set the ofset to -10% but this leaves the indoor humidity still 9% higher than actual. This will cause problems with humidification and dehumidification from the furnace. Still working for a solution, need to have Lennox look into this.

Want fan only feature, reset independent of wifi

October 06, 2025

prefer a thermostat that can reset after power bump without accessing wifi; wish it had a feature to circulate air from basement to upstairs by running the fan only.
