Installing your thermostat
You might need the following tools to install this thermostat:
- No. 2 Phillips screwdriver
- Small pocket screwdriver
- Level (optional)
- Drill and bits (3/16” for drywall, 7/32” for plaster) (optional)
- Hammer (optional)
- Electrical tape (optional)
- Switch OFF power.
To protect your equipment, switch OFF the power to your heating/cooling system at the breaker box or the system switch.
- Remove old thermostat.
Remove the old thermostat while leaving the wallplate and wiring in place.Take a picture of the wires on your old thermostat for later reference.
If you have an older thermostat with a sealed mercury tube, turn to page 2 for proper disposal instructions.
- Label wires.
Use the supplied sticky tags to label each wire as you disconnect it. 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.
- Remove wallplate.
Remove the old wallplate from the wall after all wires have been labeled and disconnected.
- 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.
- Mount wallplate for Wi-Fi thermostat.
Mount your new wallplate using screws and anchors included with the thermostat.
Drill 3/16-in holes for drywall.
Drill 7/32-in holes for plaster.
Note: The Wi-Fi thermostat requires a C wire to operate. The C, or common, wire brings 24 VAC power to the thermostat. Many older mechanical or battery operated thermostats do not require a C wire. If you don’t have a C wire, try:
- Looking for an unused wire that is pushed into the wall. Connect that wire to C and check that it is connected to the 24 VAC common at your heating/cooling system. Check the video section at wifithermostat.com.
- Installing a new wire. If required, contact a contractor to install a new wire (go to wifithermostat.com to locate a contractor in your area).
For conventional heating/cooling systems (natural gas, oil or electric furnace, air conditioner), see page 16. See “Glossary” on page 65 for further definition.
For a heat pump system, see page 17. See “Glossary” on page 65 for further definition.
