2 Remove old unit
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.
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.
Caution
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

Block
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-

4 Before you Connect Wires
Please follow these guidelines for safe and secure wire connections.
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.
Do not allow wires to touch each other or parts on thermostat.
Caution
Wires must be routed through the hole in the back plate, below the
terminal block, or they will hit parts on the cover.
Optional 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.
If you have zoned heating/cooling systems with multiple thermostats. Please

6 Check Unit cont.
Note:
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).
Congratulations, you have successfully installed your unit. Please
proceed to the OPERATING Guide to initialize the new thermostat.
7 Power Options
1) The 8022C 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.
2) The 8022C 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.

8022C Features
The 8022C 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 8022C 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 8022C separately programs 7 days a Week and a Spacial
Day - 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.
