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 newthermostat in place of the old one, unless theconditions listed below suggest otherwise. Onnew installations, follow the guidelines listedbelow.• Locate the thermostat on an inside wall, about 5ft. (1.5m) above the floor, in a room that is usedoften.• Do not locate where air circulation is poor, suchas in a corner or an alcove; or behind an opendoor.• Do not install it where there are unusual heatingconditions, such as: in direct sunlight; near alamp, television, radiator, register, or fireplace;near hot water pipes in a wall; near a stove onthe 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 tocorrosion that will shorten thermostat life.• Do not install the unit until all construction workand painting has been completed.

W A R N I N G: • Read instructions carefully before removingany 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 maynot comply with any standard.

4.3 REMOVAL OF OLD UNIT1. Switch electricity to the furnace and airconditioner OFF; then proceed with the followingsteps.2. Remove cover from old thermostat. Most aresnap-on types and simply pull off. Some havelocking screws on the side. These must beloosened.3. Note the letters printed near the terminals.Attach labels (enclosed) to each wire toidentification. Label and remove wires one at atime. Make sure the wires do not fall back insidethe wall.4. Loosen all screws on the old thermostat andremove it from the wall.

4.4 MOUNTING5. Strip insulation 3/8 in. (9.5mm) from wireends and clean off any corrosion.6. Fill wall opening with non-combustibleinsulation to prevent drafts from affecting thethermostat.7. With each thumb on a release tab at thebottom of the body, and fingers over the top ofthe unit, release the unit from its base plate bysqueezing the tabs into the body.8. Separate the unit from its base plate by pullingthe body outward at its bottom.

3

C A U T I O N:• Be careful not to drop the unit or disturbelectronic parts.• Leave the door closed while the body isbeing removed from the base.

9. Route the wires through the open areas in thebase plate above the terminals. Hold the baseagainst the wall, with the wires coming through.Position the base for the best appearance (tohide any marks from an old thermostat). Attachthe base to the wall with the two screwsprovided.

N O T E: If you are mounting the base to asoft material like plasterboard or if you areusing the old mounting holes, the screws maynot hold. Drill a 3/16-in. (4.8mm) hole ateach screw location, and insert the plasticanchors provided. Then mount the base asdescribed below.

4.5 WIRING• Using the terminal descriptions below, wiringdiagram on page 14, and your labels, determinethe appropriate wiring for your system.• Also Refer to the Heat Pump Cross-referenceChart on page 15.• If you are unsure or need assistance, call theLUX Technical Assistance Dept. (see TECHNICALASSISTANCE.)

4.5.1 TERMINAL DESCRIPTIONS• See drawing on page 16 showing layout ofterminals.

G: The fan terminal is live at any time thethermostat attempts to turn the system fan orblower 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 ofheating/cooling.

R: Transformer, Provides PowerY1: 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 WIRES10. Loosen wire clamp screwsjust enough to slide wire underthe black top part of the clamp.11. Connect stripped wire ends,by trapping it between its black clamp and brassterminal. Then tighten its terminal screw.12. Tape the ends of any unused wires.

4.5.3 COMPLETING YOUR INSTALLATION13. Install two new Energizer® or DURACELL®

"AA" size alkaline batteries at this time. Forinstructions, refer to BATTERIES/MAINTENANCE.14. Configure your thermostat at this time. Referto SETUP OPTIONS.15. Install your thermostat on its base. To dothis, hang the top of the unit by the tabs on thebase, then snap the bottom of the unit into place.Do not use unnecessary force. If the body doesnot snap into place easily, remove the body, re-hang it from tabs and try again.16. Turn the power back on to your heatingand/or air conditioning system.17. Verify that the system and its fan areoperating properly. When set to a hightemperature, the heating system should providewarm air after a short time. Likewise, a coolingsystem should provide cool air after a short time.Usually sound from the furnace and airconditioning units can be heard while they arerunning. The rush of moving air should be heardwithin a short time after either has been started.

It then makes all settings andprograms their default values before initiatingnormal operation.

N O T E: Pressing this button will overwriteyour program and install the default values ofall temperature programs and setup valuesinto the unit’s nonvolatile memory. To easereprogramming later, record your thermostat’sprograms and settings in the table providedbefore using this button. (See Page 16)

7.6 TEMPERATURE VARIATION / SWING• Your thermostat works by turning your heatingor cooling system on and off whenever the roomtemperature varies a certain number of degreesfrom the set-point temperature. This variation isthe "swing". Your system should cycle on about

10

11

3 to 6 times per hour. A smaller swing numberincreases the number of cycles, so roomtemperature is more constant. A larger swingnumber decreases the number of cycles, savingenergy in most cases.

7.6.1 SWING 1 – 1st STAGEThis setting controls when the first stage ofheating or cooling turns on and off.• In HEAT, Swing 1 sets the temperature variationthe system allows below the set temperaturebefore switching the first stage heat source on,or above the set temperature before switchingthe first stage heat source off.• In COOL, Swing 1 sets the temperaturevariation the system allows above the settemperature before switching first stage ofcooling on, or below the set temperature beforeswitching the first stage of cooling off. Tochange this value:• Rotate the SPEED DIAL® to ENERGY USAGE.• Press NEXT and HOLD simultaneously. TheTemperature section of the display shows SETTEMP SWING and 1 denoting that you aresetting SWING 1. The Time section flashes thecurrent setting.• Select one of the 9 values from 025 to 225 withthe UP/DOWN buttons.• Return the SPEED DIAL® to RUN.

7.6.2 SWING 2 – 2nd Stage • This setting controls when the second stage ofheating or cooling turns on and off. It controlsthe temperature variation the system allowsabove and below Swing 1’s limit before callingfor a second stage. Once a second stage isactivated, it will remain on until the settemperature has been reached. (Note: TheSwing setting for the 3rd Stage of EmergencyHeat is not adjustable, it will always equal that ofSwing 2).

To change this value:• Rotate the SPEED DIAL® to ENERGY USAGE.• Press NEXT and COPY simultaneously. TheTemperature section of the display shows SETTEMP SWING and 2 denoting that you aresetting SWING 2. The Time section flashes thecurrent setting.• Select one of the 9 values from 025 to 225 withthe UP/DOWN buttons.• Return the SPEED DIAL® to RUN.

7.7 DEAD BAND• When using Auto-Changeover, dead bandprovides a disallowed temperature range betweenthe maximum heat set temperature andminimum cool set temperature. Dead Band maybe set from 1 to 6 degrees. For example, withauto-changeover active, dead band set to 3˚F andheat set to 70˚F, the minimum allowed cool settemperature will be 73˚F. If the cool settemperature is lowered, then the heat settemperature will be lowered by the same amountmaintaining the 3˚F Dead band.

To change this setting:• Set SPEED DIAL® to RUN.• Set Temperature MODE to AUTO.• Press NEXT and COPY simultaneously to 2seconds. The display shows SET DEAD BAND,while the Time/Temperature section flashes thecurrent setting.• Use UP/DOWN keys to adjust the DEAD BANDin 1-degree increments.• Press and release NEXT to return to RUN. Or,after 30 seconds the unit will automaticallyreverts to RUN mode.

8. SET UP OPTIONS• See drawing on page 16. There are fivejumpers on the circuit board. Each controls asetting depending on its position. Jumpers arelocated on the rear of the thermostat’s circuit

12

board. For reference, there are a table of settingsand jumper positions printed there as well. Theyare described here from J3, the rightmostjumper, to J7, the leftmost jumper.

8.1 MINIMUM RUN TIME – J3• The position of J3 sets the minimum length oftime that the thermostat must remain with HEATor COOL either on or off before it willautomatically switch to the alternate On or Offstate. This feature prevents short cycling, andprovides compressor protection for cooling units.Choices are 2 or 5 minutes. Default position asshipped is 5 minutes.

8.2 CLOCK FORMAT – J4• The time shown on the thermostat’s clock maybe display in 12 or 24-hour format. Set thisoption to your preference. Default position asshipped is 12-hour format.

8.3 TEMPERATURE DISPLAY FORMAT (F/CDISPLAY) – J5• Temperature may be displayed in Fahrenheit orCelsius with this option. Default position asshipped is F.

8.4 SMART RECOVERY – J6Smart Recovery allows your HVAC system toattempt to recover from a setback period andreach your desired comfort temperature by thebeginning of your programmed comfort period.This jumper allows you to choose SmartRecovery to be On or Off. Default position asshipped is Off.• An initial Smart Recovery will start _ hourbefore the programmed comfort temperature.• Maximum Smart Recovery time is one hour.• If enabled, Smart Recovery will initiate if:• Recovery is valid, from an evening setback tomorning comfort or day setback to eveningcomfort period.• In Heat mode, the set temperature of the

comfort period must be higher than the setbackperiod.• In Cool mode, the set temperature of thecomfort period must be lower than the setbackperiod.

8.5 FAN OVERRUN TIME – J7 • When this feature is enabled, Delay ON timebetween the 1st stage of the compressor and fanis 5 seconds and Delay OFF between the 1ststage of compressor and fan is 1 minute.• When this feature is disabled, there is no delaytime between 1st stage of the compressor andthe fan. Default position as shipped is Disabled.

8.6 REPOSITIONING JUMPERSSee the diagram on Page 16 to determine thejumper position corresponding to the option youdesire. The table is also printed on the circuitboard. If necessary, change the jumper positionby pulling it straight off the pins it covers.Replace the jumper over one pin for OPEN, orboth pins for CLOSED. When all changes havebeen made, press the Hardware Reset Button.See HARDWARE RESET.These jumpers are located inside the thermostaton the rear of its circuit board. To access them,remove the unit from the wall by pressing up onthe thumb latch at the bottom of thermostat, andswinging the body up and away to separatethem.To change a setting, the jumper must berepositioned and a Hardware Reset must beperformed. See HARDWARE RESET.

WIRING DIAGRAM NOTES

1. Dashed wires are optional.2. If an "E" wire was connected to your old thermostat, it should be re-connected to the "E" terminal onthe new thermostat, and the optional jumper between "W" and "E" should not be used. Install this optionaljumper if you would like to use auxiliary heat as an emergency heat system.3. Optional common wire to terminal "C" allows system power to power thermostat instead of batteries.4. Use "B" or "O" wire but not both. Refer to equipment manufacturer's instructions to determine whichone to use.5. If a "Y" and "C" wire are both present in your system, then "C" is the common wire.6. Warning: If a "B" wire in you system is a common wire and you connect it to the "B" terminal instead of"C", this may cause damage to you system.7. Use terminal "Y2" only if you have a second compressor stage.

WARNING: THIS IS A LOW VOLTAGE THERMOSTAT (24 volts). A SERIOUS RISK OF FIRE EXISTS IFYOU CONNECT THIS THERMOSTAT TO A LINE VOLTAGE APPLICATION (typically 115 or 230 volts). IFUNCERTAIN ABOUT THE VOLTAGE CONSULT A PROFESSIONAL ELECTRICIAN.
