You want to save on energy bills without sacrificing comfort. This renewed Honeywell Home Wi-Fi thermostat is built for busy homeowners who want control from anywhere. Unlike basic models, it gives you 7-day programming with 4 periods per day, so you can set different temperatures for weekday mornings, work hours, evenings, and weekends.
Requires a C-wire for power. If your system lacks one, use the included G-wire jumper cable. Once connected, adjust temperature from your phone using the free app. Works with Alexa so you can change settings with your voice. Check local weather from the app or web portal. Compatible with most systems except electric baseboards.
