Please read all instructions carefully before beginning instal-
lation and save for future reference. Before removing any
wiring from your existing thermostat, its wires must be labeled

since they may not comply with any standard.

from your investment, please read this manual and acquaint yourself with
your purchase before installing your new thermostat. Then follow the

THERMOSTAT LOCATION
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.
Remember that your PSD111 may be mounted vertically or horizontally
when determining the optimal location.
Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the
floor, and in a room that is used often.
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.
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.
Do not locate in a damp area. This can lead to corrosion that will
shorten thermostat life.
Do not locate where air circulation is poor, such as: in a corner or an
alcove; or behind an open door.
Do not install the unit until all construction work and painting has been
completed.
