Comfort Sync® A3 Thermostat Product Brochure

Remote Access extends control to anywhere.

The Comfort Sync thermostat puts advanced temperature monitoring and adjustment in your hands, no matter where you may be. Check and change the temperature in your home or set your system into an energy-saving Away Mode using your smartphone, tablet, laptop or other web-enabled device. So you’ll always come home to the perfect temperature.

Enjoy faster, more responsive service

Another incredible feature gives Comfort Sync the ability to email you and your dealer when routine maintenance or service needs to be performed. This gives you the added peace of mind that your system will be operating precisely as soon as possible. Each service alert and reminder is customizable for various time increments, depending on system requirements, so you remain in control.

Tailored performance for every room.

Comfort Sync Zoning divides your house into two, three or four different areas, or “zones,” and redirects heating and cooling to those zones as needed. So you can keep temperatures right where you want them, without wasting energy on little-used areas.
