For accurate temperature control and comfort, correct location is very important. On
new installations, the guidelines listed below should be followed as closely as
possible. When replacing an old thermostat, install the new one in the same location
unless these conditions suggest otherwise.
1. Locate the thermostat on an inside wall about five feet above the floor, where it is
easy to install and adjust. It should be in a room that is used often, such as a family
room.
2. Do not install it where there are unusual heating conditions, such as direct sunlight,
close to a lamp, radio, television, radiator, register, near a fireplace, or other heat
producing appliance. Also, check for hot water pipes within the wall, or a stove on
the other side of the wall.
3. Do not locate in unusual cooling conditions, such as on an outside wall, or one
separating an unheated room, or in drafts from stairwells, doors, or windows.
4. Do not locate in a damp or humid area. This can shorten thermostat life due to
corrosion.
