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)

• 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.

Installing your thermostat

• 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 honeywellhome.com/wifi-thermostat
• Label wires.
  Do not label by wire color. 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 the 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.

Installing your thermostat

• Mount wallplate for thermostat. Mount your new wallplate using screws and anchors included with the thermostat.
  If necessary:
  • Drill 3/16-in holes for drywall.
  • Drill 7/32-in holes for plaster.

Note: You may be able to use your existing wall anchors. Hold the wallplate up to the existing anchors to check for alignment

Important! The 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.

Note: Not all heating/cooling systems label the 24 VAC common C. Check your system manual or contact the manufacturer to find out which terminal is the 24 VAC common.
