Getting started

Check package contents:

• Thermostat
• Large print subbase switch labels
• Coverplate
• Wall anchors & screws (2 each)
• Wire labels
• Braille Card

Thermostat is for 24 Vac heating and cooling systems

This thermostat contains a Lithium battery which may contain Perchlorate material. Perchlorate Material—special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate

Before you begin, make sure you have:

• No. 2 Phillips & small pocket screwdrivers
• Hammer
• Level (optional)
• Pencil
• Drill and bit (3/16” for drywall, 7/32” for plaster)

Remove your old thermostat

CAUTION: TURN OFF POWER
Turn off power to system at the furnace, or at the fuse/circuit breaker panel before you begin.
Remove cover and thermostat, but leave wallplate with wires attached

Leave wallplate in place

MERCURY NOTICE
If your old thermostat contains mercury, contact your local waste management authority for proper disposal instructions.

Label wires and remove old wallplate

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.
If your old thermostat has 7 or more wires (not counting terminals C or C1), you may have purchased the wrong replacement thermostat. Stop now and call 1-800-468- 1502 for advice.

Mount thermostat base

Subbase and base installation

1. Pull wires through wire hole. Position coverplate on wall, level and mark hole positions.
2. Drill holes (3/16” for drywall, 7/32” for plaster) and tap in supplied wall anchors.
3. Pull wire through coverplate and subbase, position over anchors, then insert and tighten mounting screws. Check level if desired.
4. Apply the large-print labels to the coverplate, matching the labels on the subbase.

Wiring

1. Match each labeled wire with same letter on terminal.
2. Use a screwdriver to loosen screw terminals, insert bare wire into slots, then tighten screws.
3. Push any excess wire back into the wall opening

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

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

Fan operation settings

Move the switch to the proper setting for your system:

• F: For gas or oil heating systems, leave the fan operation switch in this factoryset 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.)

Cycle rate settings

Thermostat mounting

1. Align the slots on the base with tabs on 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

Operation

CAUTION : EQUIPMENT DAMAGE HAZARD
Do not operate cooling system when outdoor temperature is below 50
