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.

CAUTION

• 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.

REMOVING THE OLD THERMOSTAT

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 for identification. Remove and label 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. MOUNTING THE PSP511A/PSP511LA

5. Strip insulation leaving 3/8 in. (9.5mm) bare wire ends and clean off any corrosion.

6. Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat. CAUTION  Be careful not to drop the unit or disturb electronic parts. Leave the door closed while the body is being removed from the base.

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.

8. Hold the base against the wall. Route the wires through the hole below the terminal block. Position the base for best appearance (to hide any marks from an old thermostat). Attach the base to the wall with the two screws provided.
   CONNECTING THE WIRES

9. Loosen wire clamp screws just enough to slide wire under the top black part of the clamp.

10. Using your label, and diagrams below determine appropriate wiring for your system.

11. If you are unsure or need assistance, call the LUX Technical Assistance Dept.(see TECHNICAL ASSISTANCE).

12. Slide proper wire between the brass back and black top clamp.

13. Tighten each screw securely.  
    Dashed lines are optional.
    Optional common wire allows system to power thermostat.
    If “Y” and “C” are both present, then “C” is a common wire.
    If a “B” wire in your system is a common wire then connecting it to the B terminal may cause damage to your system.
    Use “B” or “O” in heat pump systems. Generally neither are required in a conventional system.
    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.

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. 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.
    NOTE  If you have an electric system and the blower does not operate after installation, find the electric/gas heat jumper on the back of the body. Move the jumper to ELEC position. No reset required.

OPERATING INSTRUCTIONS

The PSP511A/PSP511LA alternately displays the current time and the room temperature, and the day of the week. The current program period, MORN, DAY, EVE or NITE is indicated by an arrow at the left edge of the screen. Set temperatures are indicated in the right side of the display.
With batteries installed, you can make program or setting changes with the thermostat body on the wall, or conveniently removed from its base plate.

TEMPERATURE CONTROL MODES:
The Mode switch has three positions HEAT, OFF, and COOL. In the winter, set the system switch to HEAT to control your heating system. In the summer, set the switch to COOL to control your air conditioner. In spring and fall or when the windows are open, you can set the switch OFF.

UP/DOWN/CHANGE KEYS:
UP/DOWN keys are just right of the unit’s display. They are used to adjust set temperatures and change other settings.

CHANGING TEMPERATURE AND OTHER SETTINGS:
If there are many choices for a value, usually that setting will automatically advance by holding the Up or Down key. Some settings though, must be changed one press at a time.

DISPLAY ILLUMINATION:
Press any key to illuminate (PSP511LA only) the display. Pressing any key will keep the display illuminated until no button has been pressed for approximately 20 seconds.

FAN MODES:
The fan switch has two positions; AUTO will automatically run your system’s fan as required for heating and cooling only. ON runs your system’s fan continuously.

NOTE
The FAN switch works only if your system provides a wire for the PSP511A/PSP511LA’s “G” terminal.

SETTING THE TIME AND DAY:
Open the door on the front of the thermostat. Rotate the dial to the SET DAY/TIME position. You should see the display pictured below with a day of the week flashing.

• Press UP to change day of week.
• Press NEXT to set the time;it will flash.
• Press UP or DOWN to change time of day.

When you are finished setting the day and time, rotate the dial to RUN to return to normal operation or to another position to continue programming.

HARDWARE RESET
This button will read option jumper positions, before the unit begins normal operation. It is located inside on the rear of the unit’s circuit board. It is a small square component with a white button at it’s center. Pressing Hardware Reset will allow the unit to read the new jumper settings without losing your program.

SOFTWARE RESET
Use this front panel RESET to return all software settings and programs to their default values. Option jumpers will be read and operation will correspond to their current positions. To assist in reprogramming, copy your programs into the chart provided before using SOFTWARE RESET.

PROGRAMMING CHART

PROGRAMMING

The PSP511A/PSP511LA provides two separate programs, one for heating the other for cooling. Each program has separate settings for weekdays and week-ends. Every day a program cycles through four independent periods. You can use the default programs or alter them to suit your schedule.

DEFAULT ENERGY STAR® TEMPERATURE PROGRAM
As supplied from the factory, the following ENERGY STAR® approved program will be used for temperature control in RUN mode. This program and all other software settings may be restored to their default values via a SOFTWARE RESET.

EDITING HEAT OR COOL PROGRAMS
You can review or change any preset times and/or temperatures to suit your schedule for each day of the week. The four periods each day are Morning(MORN), Day,(DAY) Evening(EVE), and Night(NITE).

WEEKDAY PROGRAMMING

1. Select HEAT or COOL with the mode switch.
2. Rotate dial to SET WEEKDAY PROGRAMS. You will see the display shown here:
3. All 5 weekday abbreviations will be displayed indicating that this program will cycle once each of these days,
4. The HEAT or COOL set temperature will be displayed on the right side of the display. The start time for the displayed period will flash to show that this may be changed.
5. Use the Up and Down keys. One period ends at the start time of the next period. The beginning of that period may not be any closer to the beginning of the next period than one 15 minute increment.
6. Press NEXT to accept the displayed start time and advance to edit the SET TEMPERATURE.
7. Use the UP and Down keys to change the flashing HEAT or COOL set temperature to the temperature you desire.
8. Press NEXT to accept the displayed set temperature and advance to edit the start time for the next period. It will be flashing.
9. Repeat for each of the four periods. When all the periods for the weekday program have been set, the start time for the morning will again be displayed flashing so that it may be edited.
10. Rotate the dial back to RUN to accept all current values and end the weekday programming session.

WEEKEND PROGRAMMING

1. To review or change the weekend program, select HEAT  or COOL and rotate the dial to SET WEEKEND PROGRAMS. You will see a display similar to that shown here:
2. Use steps 4 – 10 described in WEEKDAY PROGRAMMING to program Saturday and Sunday.

TEMPERATURE OVERRIDE
OVERRIDE allows you to change the current SET TEMPERATURE in HEAT or COOL until the next program period without changing your temperature control programs.

• Press an arrow key once.

• While the Set Temperature is flashing; press an UP or DOWN key to adjust the set temperature by one degree in the associated direction.
  Holding the key will automatically advance the setting in the associated direction.

• The OVERRIDE will be canceled at the start of the next program period, and the temperature setting will return to its programmed value.

• An OVERRIDE may be terminated by rotating the dial, switching the mode to OFF, or initiating a HOLD.

• Adjusting the set temperature to its program value will also cancel an OVERRIDE.

TEMPERATURE HOLD
HOLD may be used for manual temperature control. HOLD is the simplest means to set and maintain a fixed temperature. It allows you to set and maintain a temperature Set Point indefinitely in Heat or Cool without concern for programming. To initiate a HOLD:

• Press and release HOLD.
• After the Set Temperature begins to flash, adjust the temperature as desired with UP or DOWN keys.
• The temperature setting will not change until the HOLD is canceled.
• To cancel a HOLD, press and release HOLD again, rotate the dial, or switch mode to OFF.

ADVANCED FEATURES

TEMPERATURE SWING
A thermostat works by turning your heating or cooling system on or off whenever the room temperature varies from the set-point temperature. This variation is the “swing.” Your system should cycle on about 3 to 6 times per hour. A smaller swing number increases the number of cycles, so room temperature is more constant. A larger swing number decreases the number of cycles, but saves energy in most cases.

SWING SETTING

1. With the Dial in its RUN position, simultaneously press NEXT & HOLD.
2. Use the UP and DOWN keys to change swing.
3. Choices are 1 through 9. The default is 1.
4. Rotate the dial to the RUN position or press NEXT to finish.

SETUP OPTIONS

JUMPER SETTINGS
There are three jumpers and one switch. Each controls a setting corresponding to its position.

5MIN/2MIN MINIMUM RUN TIME – JP3
The position of J3 sets the minimum length of time that the thermostat must remain with Heat or Cool either on or off before it will automatically switch to the alternate On or Off state. This feature prevents short cycling and provides compressor protection for cooling units. Choices are 2 or 5 minutes.

TEMPERATURE DISPLAY FORMAT °F/C – JP2
The position of this jumper controls whether the temperature is displayed in degrees F° or C°

TIME DISPLAY FORMAT 12/24 HR CLOCK – JP1
The position of this jumper controls whether time is displayed in 12 hour or 24 hour Military Time format.

REPOSITIONING JUMPERS
To change a setting, the jumper must be repositioned and a HARDWARE RESET must be performed. Note that as long as you press the Hardware Reset button (inside) and not the Software Reset button (front), you will change settings and not lose your program.These jumpers are located inside the thermostat on the rear of its circuit board. To access them, remove the unit from the wall by pressing up on the thumb latch at the bottom of the thermostat and swinging the body out and away.

GAS/ELECTRIC SWITCH
This switch controls whether the thermostat requests the system fan to run when it is in HEAT mode with the fan set to AUTO. Then with the switch set to GAS the fan is controlled by the heating system itself and the terminal will remain inactive. With the gas switch set to Electric (ELEC), the fan is controlled by the thermostat.
The table pictured below is also printed on the circuit board. The closed or shorted position is that which covers both a jumpers pins. To prevent its loss in the open position, a jumper may be placed over one pin only. After jumpers have been changed, press the HARDWARE RESET button for the changes to take effect. See HARDWARE RESET
