Lux Products LUXPRO PSPHA732 Series Installation And Operating Instructions Manual
CAUTION:
Your thermostat is protected against
normal static electric discharges. To
minimize the risk of damaging the unit in
extremely dry weather, touch a grounded
metal object before touching your
thermostat.
4. INSTALLATION
4.1 TOOLS REQUIRED
• #1 Phillips screwdriver (small)
• Drill with 3/16-in. (4.8mm) bit
• Wire stripper/cutter
4.2 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.
• Locate the thermostat on an inside wall, about 5
ft. (1.5m) above the floor, in a room that is used
often.
• Do not locate where air circulation is poor, such
as in a corner or an alcove; or behind an open
door.
• Do not install it where there are unusual heating
conditions, such as: in direct sunlight; near a
lamp, television, radiator, register, or fireplace;
near hot water pipes in a wall; near a stove on
the other side of the 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 install the unit until all construction work
and painting has been completed.
WARNING:
• Read instructions carefully before
removing any wiring from an existing
thermostat.
• Label wires before they are removed.
• When removing wires from their
terminals, ignore the color of the wires
since they may not comply with any
standard.
4.3 REMOVAL OF OLD UNIT
1. Switch electricity to the furnace and air
conditioner OFF; then proceed with the following
steps.
2. 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.
3. Note the letters printed near the terminals.
Attach labels (enclosed) to each wire to
identification. Label and remove wires one at a
time. Make sure the wires do not fall back inside
the wall.
4. Loosen all screws on the old thermostat and
remove it from the wall.
4.4 MOUNTING
5. Strip insulation 3/8 in. (9.5mm) from wire
ends and clean off any corrosion.
6. Fill wall opening with non-combustible
insulation to prevent drafts from affecting the
thermostat.
7. 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.
8. Separate the unit from its base plate by pulling

pump will be disabled).
• The 3rd stage of heat will deenergize as soon as
the temperature setpoint is reached. The letters
"EMER" will disappear.
5.5 AUTOCHANGE (AUTO)
• Use AUTOCHANGE mode to allow your
thermostat to switch between HEAT and COOL
modes automatically. Slide the mode switch to
AUTO
and
AUTO CHANGE
will be displayed
above the set temperature. You can determine
whether your thermostat is in HEAT or COOL
mode by whether HEAT or COOL is visible in the
set temperature area of the units display. Initially
HEAT or COOL may not be active until a
determination is made that HEAT or COOL is
necessary.
• The programmed temperature for a given mode
will be used as the set temperature for that
mode.
• Pressing the
UP/DOWN
keys at the same time
will force the unit to change modes and make the
programmed set temperature the new set
temperature.
5.6 HEAT
• Use HEAT mode to control your furnace and

electronic parts.
• Leave the door closed while the body is
being removed from the base.
9. 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 thermostat). Attach
the base to the wall with the two screws
provided.
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.
4.5 WIRING
• Using the terminal descriptions below, wiring
diagram on page 14, and your labels, determine
the appropriate wiring for your system.
• Also Refer to the Heat Pump Cross-reference
Chart on page 15.
• If you are unsure or need assistance, call the
LUX Technical Assistance Dept. (see
TECHNICAL
ASSISTANCE
.)
4.5.1 TERMINAL DESCRIPTIONS
• See drawing on page 16 showing layout of
terminals.
G The fan terminal is live at any time the
thermostat attempts to turn the system fan or
blower on.
O Live at any time the unit is in Cool mode.
B Live at any time unit is in Heat Mode.
W Active while the thermostat is calling for
auxiliary 3rd stage of heat.
Y2 Active while calling for a 2nd stage of
heating/cooling.
R Transformer, Provides Power
Y1 Active while calling for a 1st Stage of
heating/cooling.
C Use of this terminal allows the unit to be
system powered rather than battery powered.
E This terminal is active when the thermostat is
calling for Emergency Heat.
4.5.2 CONNECTING THE WIRES
10. Loosen wire clamp screws
just enough to slide wire under
the black top part of the clamp.
11. Connect stripped wire ends,
by trapping it between its black clamp and brass
terminal. Then tighten its terminal screw.
12. Tape the ends of any unused wires.
4.5.3 COMPLETING YOUR INSTALLATION
13. Install two new Energizer®or DURACELL
®
"AA" size alkaline batteries at this time. For
instructions, refer to BATTERIES/MAINTENANCE.
14. Configure your thermostat at this time. Refer
to SETUP OPTIONS.
15. Install your thermostat on its base. To do
this, hang the top of the unit by the tabs on the
base, then snap the bottom of the unit into place.
Do not use unnecessary force. If the body does
not snap into place easily, remove the body, rehang it from tabs and try again.
16. Turn the power back on to your heating
and/or air conditioning system.
17. Verify that the system and its fan are
operating properly. When set to a high
temperature, the heating system should provide
warm air after a short time. Likewise, a cooling
system should provide cool air after a short time.
Usually sound from the furnace and air
conditioning units can be heard while they are
running. The rush of moving air should be heard
within a short time after either has been started.

5.12.3 CLEAN CYCLE™
• LUX’s Clean Cycle™ allows you to program a
forced air system to flow air through your
system’s filter, cleaning the air in your home,
even when heating or cooling is not being
utilized. In CLEAN mode the fan maintains the
programmed minimum run time; it may run
additional time as required to maintain
temperature control. The program used avoids
additional fan time when the minimum run time
has been met over the last hour through
temperature control. Minimum fan run times are
met by running one-third the hourly requirement
at twenty-minute intervals. The default minimum
fan run time is 15 minutes per hour.
5.13 DISPLAY ILLUMINATION
