Installing your thermostat
You might need the following tools to install this thermostat:

• No. 2 Phillips screwdriver
• Small pocket screwdriver
• Pencil
• Level (optional)
• Drill and bits (3/16” for drywall, 7/32” for plaster) (optional)
• Hammer (optional)
• Electrical tape (optional)

1. Switch OFF power to your heating/cooling system. Important! To protect your equipment, switch OFF the power to your heating/cooling system at the breaker box or the system switch.
2. Remove the old thermostat faceplate and leave the wires connected. Take a picture of the wire connections for later reference.  If no wire is connected to a terminal labeled C or no C terminal exists on the old thermostat, view the Alternate Wiring videos at wifithermostat.com/videos If you have an older thermostat with a sealed mercury tube, turn to page 2 for proper disposal instructions.
   Important! C wire is required and is the primary power source for your thermostat. Without a C wire, your thermostat will not power up. Label wires. Do not label by wire color. Use the supplied sticky tags to label each wire as you disconnect it.
3. Label wires according to the old thermostat terminal designations, not by wire color.
   Note: If no tag matches a wire terminal label, write the terminal label on a blank tag.
4. Remove the wallplate. Remove the old wallplate from the wall after all wires have been labeled and disconnected
5. Separate Wi-Fi thermostat and its wallplate. On your new thermostat, grasp the finger holds on the top and bottom of the wallplate with one hand and the thermostat (front) with the other hand. Pull pieces apart.
6. Mount wallplate for Wi-Fi thermostat. Mount your new wallplate using screws and anchors included with the thermostat.
