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
systems. The user may program up to four time/tempera-
ture settings per 24 hour period. The thermostat stores
independent heating programs for 5-day (weekday) and
2-day (weekend) periods. Three "AA" Energizer® batter-
ies will maintain the stored program 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 automatically maintain a factory
preprogrammed heating temperature of 64°F.

PRECAUTIONS
If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.
R
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 electric power to system, at
main fuse or circuit breaker box, until installation
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-
mary control to test. Short or incorrect wiring will
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
comfortable building temperature. Observe the following
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. Make sure there are no pipes or duct work in that part
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
round and drill a small guide hole for sighting (see fig.
1). From basement, drill 3/4" hole in partition floor
next to guide hole. In basementless buildings, drill
1/2" hole through ceiling and into partition from above.
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
wires still attached, remove wall plate from the wall.
3. If the old thermostat has a wall mounting plate,
remove the thermostat and the wall mounting plate as
an assembly.
4. Label each wire as you disconnect it. 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
bottom portion of the thermostat. Grasp the subbase
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
6).
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
bottom of subbase, adjust until level, and then tighten
screws. (Leveling is for appearance only and will not
affect thermostat operation.) If you are using existing
mounting holes, or if holes drilled are too large and do
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
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 top of the thermostat and the six connector
pins on the thermostat with the connectors near the top of
the subbase. Gently pivot the thermostat down until the
plastic snaps lock into place (see fig. 7). Be gentle when
attaching thermostat. If the thermostat does not seem
to be attaching to the subbase 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.

SYSTEM CONFIGURATION
ENERGY MANAGEMENT RECOVERY
(EMR)
When the EMR feature is activated, the thermostat's
microcomputer automatically calculates the time it will
take to change the temperature to the next program
setting. Then the thermostat will activate the heating
system to change the temperature so that the desired
temperature is reached at or near the beginning of the
next program period (the thermostat's microcomputer
calculates 15 minutes for every 2°F temperature change).
For example, assume that the thermostat is programmed
to provide an overnight heating temperature of 62°F, and
during the next program period, programmed to begin at
6:00 AM, the programmed temperature is 70°F. With
EMR activated, the thermostat will automatically activate
the heating system at 5:00 AM, so that the programmed
temperature of 70°F is reached by about 6:00 AM.
The thermostat is shipped with the EMR feature inactive,
which means that the thermostat will activate the heating
or cooling system at, not before, the beginning of the
program period (real time).
To activate the EMR function, clip wire S3 on the back
of the thermostat (see fig. 8).
CHECK THERMOSTAT OPERATION
If at any time during testing the system does not function
correctly, disconnect electrical power at fuse box or circuit
breaker and check that all wiring is correct.
