FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
This wall-mounted, low voltage thermostat maintains
room temperature by controlling the operation of heating
and cooling systems. The user may program up to four
time/temperature settings per 24 hour period. The ther-
mostatstoresindependentheatingandcoolingprograms
for each day of the week. The thermostat will store both
heating and cooling programs simultaneously. Three
"AA" Energizer®batteries will maintain the stored pro-
gram for approximately one year, if incoming power
should fail. If power failure is extensive and the program
is lost, after power restoration, the thermostat will auto-
maticallymaintainafactorypreprogrammedheatingtem-
perature of 64°F or a cooling temperature of 82°F.

WHITE-RODGERS
Do not exceed the specification ratings.
All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting compo-
nents could cause the control to malfunction.
To prevent electrical shock and/or equipment
damage,disconnect electricpower tosystem, at
mainfuseorcircuitbreakerbox,untilinstallation
is complete.
Do not use on circuits exceeding specified volt-
age. Higher voltage will damage control and
could cause shock or fire hazard.
Do not short out terminals on gas valve or pri-
marycontroltotest. Shortorincorrectwiringwill
burn out thermostat and could cause personal
injury and/or property damage.

NEW INSTALLATION
You should program the thermostat with batteries
installed before attaching on subbase. See OPERA-
TION GUIDE for programming instructions.
SELECT THERMOSTAT LOCATION
Proper location insures that the thermostat will provide a
comfortablebuildingtemperature. Observe thefollowing
general rules when selecting a location:
1. Locate thermostat about 5 ft. above the floor.
2. Install thermostat on a partitioning wall, not on an
outside wall.
3. Never expose thermostat to direct light from lamps,
sun, fireplaces or any temperature radiating equip-
ment.
4. Avoid locations close to windows, adjoining outside
walls, or doors that lead outside.
5. Avoid locations close to air registers or in the direct
path of air from them.
6. Makesure thereare nopipes orduct workin thatpart
of the wall chosen for the thermostat location.
7. Never locate thermostat in a room that normally
warmer or cooler than the rest of the building.
8. Avoid locations with poor air circulation, such as
behind doors or in alcoves.
ROUTE WIRES TO LOCATION
All wiring must conform with local and national electrical
codes and ordinances.
1. Probe for obstructions in partition before drilling 1/2"
hole in wall at selected location. Take up quarter
roundanddrillasmallguideholeforsighting(seeFig.
1). From basement, drill 3/4" hole in partition floor
next to guide hole. In basementless buildings, drill
1/2"holethroughceilingandintopartitionfromabove.
2. Through this hole drop a light chain, or 6" chain
attached to a strong cord. Snag cord in basement
with hooked wire. In basementless buildings, drop
cord through hole in ceiling and down partitioning;
snag cord at the thermostat location.
3. Attach thermostat wire to cord and pull wire through
hole in wall so that 6" of wire protrudes.

REPLACEMENT INSTALLATION
REMOVE OLD THERMOSTAT
1. Shut off electricity at the main fuse box until installa-
tion is complete. Verify power is off with a voltmeter.
2. Remove the front cover of the old thermostat. With
wiresstill attached,removewall platefromthewall.
3. If the old thermostat has a wall mounting plate,
removethethermostatandthewallmountingplateas
an assembly.
4. FOR HEATING ONLY SYSTEMS — Disconnect the
two wires from the old thermostat. Skip steps 5
through7belowandproceedtoATTACHSUBBASE
TO WALL.
5. FOR HEATING/COOLING SYSTEMS — Before re-
moving wires from old thermostat, identify the termi-
nals that have wires attached on the old thermostat.
ThenuseTable1toidentifythetypeofthermostatyou
arereplacing. Forexample,iftheoldthermostathas
wires attached to terminals R, W, Y, and G, the old
thermostat is a type 5 (note that the old thermostat
may not have wires attached to all the terminals
identified in Table 1).
6. Use the self-adhesive labels enclosed with your
new thermostat to identify the wires attached to
the old thermostat. The labels correspond to the
thermostattypenumberyouidentifiedinstep5above
(seeTable2). Forexample,ifyoudeterminedthatthe
old thermostat is a type 5, use the labels for the type
5 thermostat (you may not use all the labels for the
typenumberyou'veidentifiediftheoldthermostatdid
not have wires attached to all the terminals).
7. Labeleachwireasyoudisconnectit. Thelabelshave
both the old terminal markings and the new terminal
identification. Discard any unused labels. PULL AT
LEAST SIX INCHES OF WIRE OUT OF THE WALL
WHEN YOU DISCONNECT IT - DO NOT ALLOW
THE WIRES TO FALL BACK INTO THE WALL.
ATTACH SUBBASE TO WALL
1. Remove the packing material from the thermostat.
Place the fingers of one hand on the center top and
bottomportion ofthethermostat. Graspthesubbase
in the other hand on the top and bottom center, and
gently pull straight out (see Fig. 2). The thermostat
has pin and socket connectors. Forcing or prying on
the thermostat will cause damage to the unit.
2. Pull wires through opening in the center of the sub-
base. DO NOT LET WIRES FALL BACK INTO
WALL.
3. Connect wires beneath terminal screws on subbase
using appropriate wiring schematic (see Figs. 3
through 11).
4. Place subbase over hole in wall and mark mounting
hole locations on wall using subbase as a template.

5. Move subbase out of the way. Drill mounting holes.
6. Fasten subbase loosely to wall, as shown in Fig. 3,
using two mounting screws. Place a level against
bottomofsubbase,adjustuntillevel,andthentighten
screws. (Leveling is for appearance only and will not
affectthermostatoperation.) Ifyouareusingexisting
mountingholes,orifholesdrilledaretoolargeanddo
not allow you to tighten subbase snugly, use plastic
expansion plugs to secure subbase.
7. Push excess wire into wall and plug hole with a fire-
resistant material (such as fiberglass insulation) to
prevent drafts from affecting thermostat operation.

ATTACH THERMOSTAT TO SUBBASE
IT IS RECOMMENDED THAT YOU SET OPTION
SWITCHESTODESIREDPOSITIONBEFOREATTACH-
ING ON SUBBASE (see OPERATION). IT IS ALSO
RECOMMENDED THAT YOU PROGRAM THE
THERMOSTAT WITH BATTERIES INSTALLED BE-
FORE ATTACHING ON SUBBASE (see OPERATION
GUIDE for programming instructions).
POWER TO THERMOSTAT MUST BE OFF BE-
FORE ATTACHING THERMOSTAT TO WALL.
FAILURE TO TURN OFF POWER BEFORE AT-
TACHING THERMOSTAT MAY CAUSE EQUIP-
MENT DAMAGE DUE TO RAPID COMPRESSOR
CYCLING.
To attach thermostat to subbase, line up the plastic snap
guides at the bottom of the thermostat and the three
connector pins on the thermostat with the connectors
nearthebottom leftsectionof thesubbase(whenviewed
fromthefront). Gentlypivotthethermostatupuntilthesix
pin connectors and the plastic snaps lock into place (see
Fig. 12). Be gentle when attaching thermostat. If the
thermostatdoesnotseem to be attaching tothesubbase
easily, make sure that the connector pins and plastic
snaps are properly aligned, and that excess wire is
pushed into the wall. Damage to the thermostat may
occur if force is used.
