1). THERMOSTAT LOCATION
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.
■■ Place Sub-Base, Figure 3, on wallplate over wall
■■ Drill two holes with 3/16” bit, 1” deep.
■■ Insert plastic screw anchors into drilled holes, flush
■■ Bring wires through large hole in decorative wall plate
■■ Referring to your notes and the following diagrams,
do not fall back inside the wall. Make note of wires
and to which terminals they are attached as you
disconnect them. For example: “Yellow wire to
terminal Y, Red wire to terminal RH,” etc.
