Installation is easy — even if you’ve never done it before!
Your new thermostat has been designed for fast, easy installation. Just follow the
simple, step-by-step instructions in the following pages.
Install in three simple steps
• Label wires and remove your old thermostat (see pages 5-8).
• Install and wire your new thermostat (see pages 9-15).
• Set your new thermostat to match your heating/cooling system
(see pages 16-21).
Installation tips
• Have everything you need ready to go before you begin (see pages 3-4).
• Do not use wire color as a guide. Use wire labels instead (see page 8).
