On replacement installations, mount
the new thermostat in place of the old
one unless the conditions listed below suggest otherwise. On new installations, follow
the guidelines listed below.

1. Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and in a

room that is used often. 

2. 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. 

3. 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. 

4. Do not locate in a damp area. This can lead to corrosion that will shorten 

thermostat life.

5. Do not locate where air circulation is poor, such as: in a corner or an alcove; or

behind an open door. 

6. Do not install the unit until all construction work and painting has been completed. 
7. This thermostat does not require leveling.

Switch electricity to the furnace and air conditioner OFF;
then proceed with the following steps.

2. Note the letters printed near the terminals. Attach labels
(enclosed) to each wire for identification. Remove and label
wires one at a time. Make sure the wires do not fall back inside the wall.

3. Loosen all screws on the old thermostat and remove it from the wall.

3. Press up on the button on bottom of thermostat

and swing the body away from the base and up
to remove the body from the base.

1. Remove cover from old

thermostat. Most are snap-on
types and simply pull off. Some
have locking screws on the
side. These must be loosened.

2. Fill wall opening with

non-combustible 
insulation to prevent
drafts from affecting
the thermostat.  

1. Strip insulation

3/8 in. (9.5mm)
from wire ends
and clean off
any corrosion.
