Thank you for your confidence in our product. To obtain the best results from
your investment, please read these instructions and acquaint yourself with your
purchase before installing your new thermostat. Then follow the installation pro­cedures, one step at a time. This will save you time and minimize the chance of
damaging the thermostat and the systems it controls. These instructions may
contain information beyond that required for your particular installation. Please
save for future reference.

they may not comply with any standard.

COMPATIBILITY

The PSP511A/PSP511LA can be used with most single stage 24 volt gas, oil
or electric heating and air conditioning systems, single stage heat pumps, or
gas millivolt heating systems. It cannot be used with 3 wire zone valves, 120
volt heating systems, or multi stage heat pumps. Ask your dealer for other LUX
thermostats to control those systems.

FEATURES

The PSP511A/PSP511LA 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.

INSTALLATION

Please read all instructions carefully before beginning installation.

CAUTION

Turn off electricity to the appliance before installing or

OFF

●

Do not short (jumper) across electric terminals on furnace or air conditioner to test
the system. This may damage the thermostat and void your warranty.

●

All wiring must conform to local codes and ordinances.

●

The thermostat should be limited to a maximum of 1.5 amps; higher current may
cause damage to the thermostat.

●

Your thermostat is a precision instrument. Please handle it with care.

servicing thermostat or any part of the system. Do not turn
electricity back on until work is completed.

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.

●

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, 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 may 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.

●

Read instructions carefully before removing any wiring from existing

thermostat.

●

Wires must be labeled before they are removed.

●

Do not allow wires to touch each other or parts on thermostat.

●

When removing wires from their terminals, ignore the color of the wires

since they may not comply with any standard.

6. Fill wall opening with non-combustible insu­lation to prevent drafts from affecting the ther­mostat.

CAUTION

7. Remove the body from the thermostat’s base by pressing the thumb latch at
the bottom center of the unit and swinging the body away.

NOTE

If you are mounting the base to 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, and insert the plastic anchors provided.

COMPLETING YOUR INSTALLATION

14. See Setup Options to configure jumpers.

15. Install two new Energizer or DURACELL "AA" size alkaline batteries at
this time. For instructions, see BATTERIES/MAINTENANCE.

NOTE

Remove sticker from display.

Do not use unnecessary force. If the body does not snap into place easily,
remove the body, re-hang it from the tabs and try again.

17. Turn the power back on to your heating and/or air conditioning system.

18. 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.

19. Your installation is now complete.

16. Install your PSP511A/PSP511LA
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.

If you have an electric system and the blower does not operate

the body. Move the jumper to ELEC position. No reset required.
