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.
●
Do not locate in a damp area. This can lead to corro-
sion 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 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 condi-
tions, such as: in direct sunlight; near a lamp, radio, tele-
vision, 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 install the unit until all construction work and
painting has been completed.
3.3. REMOVAL OF OLD UNIT
CAUTION: Read instructions carefully before removing any
wiring from existing thermostat. Wires must be labeled
before they are removed. When removing wires from their
terminals, ignore the color of the wires since they may not
comply with any standard.
●
Switch electricity to the furnace and 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 on the side. These must be loosened.
●
Note the letters printed near the terminals. Attach
labels (enclosed) to each wire for identification. Label and
remove wires one at a time. Make sure the wires do not
fall back inside the wall.
●
Loosen all screws on the old thermostat and remove it
from the wall.
3.4. MOUNTING
CAUTION: Be careful not to drop the unit or disturb electronic
parts.
●
Strip insulation 3/8 in. (9.5mm) from wire ends and
clean off any corrosion.
●
Fill wall opening with non-combustible insulation to
prevent drafts from affecting the thermostat.
●
With each thumb on a release tab at the bottom of the
body, and fingers over the top of the unit. Release the
unit from its base plate by squeezing the tabs into the
body.
●
Separate the unit from its base plate by pulling the
body outward from the bottom.
NOTE: If you are mounting the base to a soft material like
plasterboard or if you are using the old mounting holes, the
screws may not hold. Drill a 3/16-in. (4.8mm) hole at each
screw location, and insert the plastic anchors provided. Then
mount the base as described below.
●
Route the wires through the open areas in the base
plate above the terminals. Hold the base against the wall,
with the wires coming through. Position the base for the
best appearance (to hide any marks from an old thermo-
stat). Attach the base to the wall with the two screws pro-
vided.

2. COMPATIBILITY
Your PSP722E is compatible with most 24 volt gas, oil,
or electrical Heating and/or Cooling systems. It cannot be
used with 120 volt heating systems. Ask your dealer for
other LUXPRO thermostats to control those systems.

The PSP722E is capable of controlling systems with up
to two stages of heat in furnace mode. In heat pump
mode, the thermostat can be configured to control up to
two stages of compressor driven heat plus auxiliary and
emergency heat stages.
NOTE: AUX HEAT ACTIVATION IS PROVIDED AT
