C A U T I O N

Your thermostat is a precise instrument.
Please handle it with care.
Turn off electricity to the appliance before installing or
servicing thermostat or any part of the system. Do not
turn electricity back on until work is completed.
Do not short (jumper) across electric terminals at
control on furnace or air conditioner to test the system.
This will damage the thermostat and void your warranty.
All wiring must conform to local codes and ordinances.
This thermostat is designed for use with 24 volt AC and
millivolt systems. The thermostat should be limited to a
maximum of 1.0 amps; higher amperage may cause
damage to the thermostat.

On replacement installations, mount the new thermostat in place of the
old one if possible.
On new Installations, follow the guidelines listed below.
Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the
floor, and in a room that is used often.
Do not install it where there are unusual heating conditions, such as: in
direct sunlight; near a lamp, radio, television, radiator register, or
fireplace; near hot water pipes in a wall; near a stove on the other side
of a wall.

Do not locate in unusual cooling conditions, such as: on a wall separating
an unheated room; or in a draft from a stairwell, door, or window.
Do not locate in a damp area. This can lead to corrosion that will shorten
thermostat life.
Do not locate where air circulation is poor, such as: in a corner or an
alcove; or behind an open door.
Do not install the unit until all construction work and painting has been
completed.
This thermostat does not require leveling.

You will need #1 Phillips screwdriver (small) and
Drill with 3/16-in. (4.8mm) bit for this installation.

The 8022 can be used with most 24 volt gas, oil or electric heating and air conditioning systems, single-
stage heat pumps or gas millivolt heating systems. It cannot be used with 120 volt heating systems or
multistage heat pumps. Ask The Home Depot for other thermostats to control those systems.

The 8022 is programmable. There are four programming periods
per day. Each period can be programmed separately.

You can use the built-in time/temperature programs, or alter them
to suit your schedule.

The 8022 separately programs Weekdays, Saturday, and Sunday
- for both heating and cooling.

You can easily override the programmed temperatures for as little
as one programming period or for an entire vacation.

A large liquid crystal display shows time, day of the week, room
and set temperatures. It will also remind you when the filter
should be changed in your blower.

Temperature swing adjustment lets you fine-tune your system for maximum comfort and energy
efficiency.

A 4-minute minimum off time in COOL protects your air conditioning system from being damaged.

Two "AA" batteries (not included) are used to retain your time and temperature programs, and to
run the thermostat.

Caution

Switch electricity to the furnace and air conditioner OFF;
then proceed with the following steps.
Remove cover from old thermostat. Most are snap-on types and simply pull
off. Some have locking screws on the side or front. These must be loosened.
Note the letters printed near the terminals. Attach labels (enclosed) to each
wire for identification.

Label the wires one at a time. You must have all the wires labeled before
you proceed. With all wires labeled, remove them from the old unit.
Make sure the wires do not fall back inside the wall. Wind them around a
pencil to keep them from falling.
Loosen all screws on the old thermostat and
remove it from the wall.
Fill wall opening with non-combustible insulation
to prevent drafts.

Separate front from back of unit. Press up on the
catch on bottom of thermostat and swing the body
away from the base, lift up to remove the body from
the base.
Hold the base against the wall, with the wires
coming through the opening below the terminal block.
Position the base for best appearance. If you chose to use the optional Wall
Plate, put it in position before screwing base to wall.
Attach the base to the wall with the
two screws provided.
If you are mounting the base to sheet
rock or if you are using the old
mounting holes, use the plastic
anchors provided. Drill a 3/16-
in.(4.8mm) hole for the insert at each
screw location, then mount the base.

When you have finished making connections. hook
the top of the body onto the base, swing the body
down, and snap the body onto the base.

Read instructions carefully before removing any wiring from existing thermostat. Wires must be labeled
before they are removed. THERE IS NO STANDARD COLOR CODE. When removing wires from their
terminals, ignore the color of the wires since these may not comply with the standard.

Note:

FOR ADVANCED USERS ONLY

If you have an electric furnace system and the blower does
not operate after installation, remove the thermostat, turn it
over, and find the electric/gas heat selector jumper on the
back of the control unit. Switch it to "Elect"(see Diag below).

1) The 8022 can run on batteries only. (2AA Alkaline) 24VAC and MV
The batteries will last well over 1 year. If the batteries are not replaced the
thermostat will stop working. Use the MV/C power jumper position.

2) The 8022 can run on the C wire if available. 24VAC ONLY
As shown in the wiring diagrams, The C wire is the other side of the 24VAC
heating transformer. If the C wire is used, the batteries are then for AC power
loss only and will last much longer. The thermostat will continue working if the
batteries die. Use the MV/C power jumper position.

3) The 8022 can run on 24VAC series power. 24VAC ONLY
Power for the thermostat comes from the W and RH wires. The batteries are
then for AC power loss only and will last much longer. The thermostat will
continue working if the batteries die. Use the FURN power jumper position.

To locate the Power Mode
Jumpers. Remove the
control unit from the wall
mount, turn it over, and
locate the jumper. It is set
at the factory on MV/C.
Change it from MV/C to
FURN to use series
power.

This option works with
24VAC, .1 to 1 amp.
systems only. Verify
operation. If it doesnt work
go back to options 1 or 2 above.

The 8022 requires batteries to operate
your furnace and retain its programming in
memory.
Switch MODE switch to OFF and
the FAN switch to AUTO.
Remove the front panel battery cover and
install 2 AA alkaline batteries according to
the polarity noted in the compartment.
Initially, all LCD segments will go on.
Press the RESET button to clear transient
program memory.
NOTE: Replace the batteries when this LOW battery
indicator appears on the display or once a year. When
replacing batteries, you have approximately one minute before
your custom program is lost.

Follow these procedures to verify you have correctly installed the unit.

To check HEAT mode:
Set the mode switch to HEAT. Set the fan
switch AUTO.
Using the TEMP UP button raise the set point
to 90deg allow the system 5 min to respond.
Verify that heat is blowing from the system.

To check COOL mode:
Set the mode switch to COOL.
Press the TEMP DOWN button to a temp 5
degrees below the room temperature.
Allow the system 5 minutes to respond.
Verify that cool air is blowing from the system.

To check Fan: (If you connected the G wire - fan relay)
Switch the FAN switch to the ON position. Verify that air is blowing from
the system. Return to AUTO position for normal operation.

Please follow these guidelines for safe and secure wire connections.

Determine which step-by-step wiring diagram you should use. Make sure your
wires are labeled. This may require you to find the 'other end' connection for each
wire on your heating or air conditioning equipment and read the label there.
If you have a wire marked "C" its connection is optional. If you do connect it the
thermostat will draw power from the C wire and this will extend battery life.

Optional Wire Connections

5 What Wires Do You Have?

Strip insulation 3/8 in. (9.5mm) from wire ends.
Take care not to damage the labels for each wire in handling.
Connect labeled wires only to a terminal with corresponding letter.
Bend the wire slightly, insert the wire under the contact plate and
tighten the screw down onto the wire.
