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 old thermostat faceplate
and leave wires connected.
2a Take a picture of the wire
connections for later reference.
2b 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/support
Important! C wire is required and
is the primary power source for your
thermostat. Without a C wire, your
thermostat will not power up.
3 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.
4 Remove wallplate.
Remove the old wallplate from
the wall after all wires have been
labeled and disconnected.

6 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.
Wallplate
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.

Smart Response Technology
This feature allows the thermostat to “learn”
how long the heating/cooling system takes
to reach programmed temperature settings,
so the temperature is reached at the time
you set.
For example: Set the Wake time to 6:00 am,
and the temperature to 70 °F (21 °C). The
heat will come on before 6:00 am, so the
temperature is 70 °F (21 °C) by 6:00 am.
Note: System setting function 13 controls
Smart Response Technology. See “Smart
Response Technology” on page 19.
The message Recovery is
displayed when the system is
activated before a scheduled

Compressor protection
This feature forces the compressor to wait
a few minutes before restarting, to prevent

Auto changeover
This feature is used in climates where both air
conditioning and heating are used on the same day.
When the system is set to Auto, the thermostat
automatically selects heating or cooling depending
on the indoor temperature.
Heat and cool settings must be at least 3 °F (1.7 °C)
apart. The thermostat will automatically adjust
settings to maintain this 3 °F (1.7 °C) separation.
Note: System setting function 12 controls Auto
changeover. See “Manual/Auto Changeover” on page
