•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.

Install guide 3M-22
Caution |
To avoid electrical shock and to prevent damage to the furnace, air conditioner, |
and thermostat, disconnect the power supply before beginning work. |
|
|
This can be done at the circuit breaker, or at the appliance. |
Tools |
You will need a small Phillips screwdriver and possibly a drill |
|
with 3/16-in. (4.8mm) bit for wall mounting. |
Location |
|
Replacement installations - mount the new thermostat in place of the old one.
New installations - follow the guidelines listed below. |
|
• Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floo |
|
in a room that is used often. |
PG 1 |
•Do not install it where there are unusual heating conditions, such as: in direct sunlight; near a lamp, radio, television, radiator registe
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, doo
•Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.
•Do not locate where air circulation is poo
such as: in a corner or an alcove; or behind an open doo r .
•Do not install the unit until all construction work and painting has been completed.

IMPOR TANT : LABEL ALL WIRE
• Switch electricity to the furnace and BEFORE DISCONNECTING THEM! 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.
Caution |
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 any standard. |
|
PG 3 |
• Label the wires one at a time. |
You mustbeforelabel all the wi |
you proceed. With all wires labeled, remove them from the old unit.
•Make sure the wires do not fall back inside the wall. 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.
Prepare wires
•You will need at least 2.6" of wire for each of your connections to the 3M-22.
•If you do not have enough wire, splice additional wire to allow enough slack.
•Fan out wires below the hole as shown.

Please follow these guidelines for safe and secure wire connections.
• Easy Terminals do not require stripping the wire.
•Clip any bare wire from previous installation.
•T ake care not to damage the labels for each wire in handling.
•Fan wires out as illustrated with 3M-22 below the wall opening.
•Wires will dress behind the 3M-22 and up over the terminal area.
•Use the Step-By-Step diagram as your guide.
•Do not bunch wires behind 3M-22. Feed slack back into the wall opening.
Caution Do not allow wires to touch each other or parts on thermostat.
• Insert the wire in the terminal and tighten |

What wires do you have? |
|
|
|
Determine which step-by-step wiring diagram below 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" it is optional. If you do connect it, the thermostat will draw power from the C wire. This extends battery life. PG 6
