Installation

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 9-16).
• Set your new thermostat to match your heating/cooling system (see pages 17-20).

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).

Pre-Installation Checklist

Check to make sure your package includes the following items:

Required tools & supplies

• No. 2 Phillips screwdriver
• Small pocket screwdriver
• Drill
• Drill bit (3/16” for drywall, 7/32” for plaster)
• Hammer
• Pencil
• Electrical tape
• Level (optional)
• Two fresh AA alkaline batteries

Remove your old Thermostat

1. Turn off power at heating/cooling system (or fuse/circuit-breaker panel).
2. Remove cover and thermostat, but leave wallplate with wires attached.

Did you purchase right thermostat?
Count wires to check. Count the number of wires coming out of the wall and attached to terminals in your old thermostat. If any of them are attached to a terminal marked “C” or “C1” do not count that wire in your total.
If the total (not counting C or C1) is 5 wires or less, proceed to the next page. If you have 6 or more wires, your new thermostat may not be compatible with your system. Stop installation and call 1-800-468-1502 for advice.

Identify Wires you will not use

If any wires are not attached to terminals in your old thermostat, do not connect them to your new thermostat. If a wire is attached to a terminal marked “C” or “C1,” disconnect it. You will not connect it to your new thermostat.
Wrap the bare metal ends of each unused wire with electrical tape, so it cannot touch and short out other wires.

Label wires and remove old thermostat
Use a screwdriver to disconnect wires one by one. As you disconnect each wire, wrap it with the label matching the letter on your old thermostat. (Adhesive labels are supplied in your thermostat package.)
Remove the old wallplate only after all wires are labeled. Be careful not to let loose wires fall into the wall opening.

IGNORE WIRE COLORS: Use only letter designations to identify wire types.

Remove Wall Plate and install Quick reference card

Pull at bottom to remove thermostat from wallplate.

Insert quick reference card after wallplate is mounted (see mounting instructions on page 11).

Mark Wallplate mounting position

Mount Wallplate

Connect Wires (Typical Installation)

Labels don’t match?
If labels do not match letters on thermostat, see next page.

Connect wires (less common wire designations)
If labels do not match letters on the thermo-stat, check the chart at right and connect to terminal as shown here (see notes, below).

1. If wires will be connected to both R and Rc terminals, remove metal jumper (see page 12).
2. Do not use C, X, or B. Wrap bare end of wire with electrical tape.
3. Do not connect both O and B if you have a heat pump. Connect O wire to O. Wrap B wire with electrical tape and do not use.

Install Batteries

Set Fan operation Switch

Move the switch to the proper setting:

• F: For gas or oil heating systems, leave the fan operation switch in this factory-set position (for systems that control the fan in a call for heat).
• E: Change the switch to this setting for heat pump or electric heat systems. (This setting is for systems that allow the thermostat to control the fan in a call for heat, if a fan wire is connected to the G terminal.)

Mount thermostat and restore electrical power

1. Align the 4 tabs on the wallplate with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps into place.
2. Restore electrical power at the heating/cooling system, or at the fuse/circuit-breaker panel.

TIP: If wires interfere when you try to mount the thermostat, push excess wire back into the wall opening.
