Honeywell T6 Pro manual

Using any smartphone or tablet device, you may alter the temperature settings on the Honeywell T6 Pro programable thermostat while you’re away from home. You can install a T6 Pro yourself if you know how to install a light fixture. With the Honeywell Home skill for Alexa, you can use your voice and routines to communicate with your Honeywell Home environment. Auto-changeover is available on the T6 Pro thermostats. Based on the room temperature and the heating and cooling setpoints, the thermostat can switch between heating and cooling as needed. If “auto” isn’t shown as an option on your thermostat, it hasn’t been set up for auto-changeover.

Getting the most out of your Honeywell thermostat requires some understanding of how to use it. That’s where having the owner’s manual comes in handy. With proper usage, there is less risk of damage, and you’ll learn how to get the most out of it.
