INSTALLATION
REMOVE OLD THERMOSTAT
1. Shut off electricity at the main fuse box until installation is
complete. Ensure that electrical power is disconnected.
2. Remove the front cover of the old thermostat. With wires
still attached, remove wall plate from the wall. If the old
thermostathasawallmountingplate,removethethermostat
and the wall mounting plate as an assembly.
3. Identify each wire attached to the old thermostat using
the labels enclosed with the new thermostat.
4. Disconnect the wires from old thermostat one at a time. DO
NOT LET WIRES FALL BACK INTO THE WALL.
5. Install new thermostat using the following procedures.
ATTACH THERMOSTAT BASE TO WALL
1. Remove the packing material from the thermostat.
2. If necessary, cut the non-electric heat jumper (see NON-
ELECTRICHEATSYSTEMS)and/ortheEMRjumper(see
ENERGY MANAGEMENT RECOVERY). Check the set-
ting of the O/B switch (see O/B TERMINAL SWITCH
SELECTION).
3. If you want to program the thermostat before mounting the
thermostat on the wall, see ARMCHAIR PROGRAMMING.
4. Gentlypullthethermostatcoverstraightoffthebase.Forcing
or prying on the thermostat will cause damage to the unit.
5. Check that the SYSTEM switch is in the OFF position.
Connect wires beneath terminal screws on base using
appropriate wiring schematic (see figs. 3 through 5).
6. Place base over hole in wall and mark mounting hole
locations on wall using base as a template.
7. Move base out of the way. Drill mounting holes.
8. Fasten base loosely to wall, as shown in fig. 2, using two
mounting screws. Place a level against bottom of base,
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 base snugly, use
plastic screw anchors to secure subbase.
9. Pushexcess wireintowall andplug holewitha fire-resistant
material(suchasfiberglassinsulation)topreventdraftsfrom
affecting thermostat operation.
NON-ELECTRIC HEAT SYSTEMS
Read the following information before clipping the non-electric
heat jumper. If you are unsure of your application, contact a
qualified serviceperson.
If your emergency or auxiliary system is non-electric (gas, oil,
etc.) and will energize the blower, then jumper, W904, on the
back of the thermostat base must be cut (see fig. 1).
If your emergency or auxiliary heat system is electric and
requires that the thermostat energize the fan circuit, do not cut
jumper W904.
ENERGY MANAGEMENT RECOVERY
(EMR)
WhentheEMRfeatureis activated,thethermostat'smicrocom-
puter automatically calculates the time it will take to change the
roomtemperaturetothenextprogramsetting.Thenthethermo-
stat will start the heating or cooling system before the next
programmed period so that the desired temperature is reached
at or near the beginning of the next program period (the
thermostat calculates 30 minutes for every 2°F temperature
change).
For example, assume that the thermostat is programmed to
provide an overnight heating temperature of 66°F, and during
thenextprogramperiod,beginningat6:00AM,theprogrammed
temperature is 70°F. With EMR activated, the thermostat will
automatically start the heating system at 5:00 AM, so that the
programmedtemperatureof70°Fisreachedbyabout6:00AM.
Iftheovernightroomtemperaturedropsonlyto68°,thethermo-
stat will start the system at 5:30 to reach the programmed
temperature of 70°at 6:00.
The thermostat is shipped with the EMR feature active, which
means that the thermostat will start the system before the
beginning of the next program period. This feature provides
betterefficiencybyallowinggradualtemperaturechangesusing
only the first stage of heat and cooling.
To de-activate the EMR function, clip wire W903 on the back
of the thermostat (see fig. 1). The thermostat will then wait until
the programmed time to start the system for a temperature
change. This may cause the more costly electric second stage
of heating to be used.

O/B TERMINAL SWITCH SELECTION
The O/B switch on this thermostat is factory set to the “O”
position. This will accommodate the majority of heat pump
applications, which require the changeover relay to be ener-
gized in COOL. If the thermostat you are replacing or the heat
pump being installed with this thermostat require the “B” termi-
nal, to energize the changeover relay in HEAT, the O/B switch
must be moved to the “B” position.
ARMCHAIR PROGRAMMING
Armchair Programming is a unique feature that allows your
thermostattobeprogrammedbeforebeingmountedonthewall.
If you do not want to Armchair Program, the thermostat can be
programmedafterbeingmountedonthewallandsystempower
turned on.
If you wish to Armchair Program your thermostat, temporarily
hold a new 9-volt battery against the wires in the battery cutout
on the back of the thermostat base for approximately 45 sec-
onds. This will provide a charge that will last approximately 30
to 45 minutes to allow the thermostat to be programmed. After
programming, the thermostat must be mounted on the wall,
wires connected and system power turned on.
Tohavesufficienttimetocompletetheinstallationwithoutlosing
the programming, hold the 9-volt battery to the terminals on the
back of the base for 30 to 45 seconds again after programming
the thermostat. The battery must be removed before mounting
the thermostat on the wall.

PROGRAMMING YOUR THERMOSTAT
Nowyouarereadytoprogramyourthermostat.Thissectionwill
help you plan your thermostat’s program to meet your needs.
For maximum comfort and efficiency, keep the following guide-
lines in mind when planning your program.
• When heating (cooling) your building, program the tem-
peraturestobecooler(warmer)whenthebuildingisvacant
or during periods of low activity.
• During early morning hours, the need for cooling is usually
minimal.
Look at the factory preprogrammed times and temperatures
shown below. If this program will suit your needs, simply press
the RUN PRGM button to begin running the factory preset
program.
If you want to change the preprogrammed times and tempera-
tures, follow these steps.
1. Determinetheheatingandcoolingtemperaturesyouwantto
use.You mayselect upto fourheatingtemperatures(HEAT
1, HEAT 2, HEAT 3, and HEAT 4), and up to four cooling
temperatures (COOL 1, COOL 2, COOL 3, and COOL 4).
Usethetablebelowtowritedownthetemperaturesyouhave
selected.
2. Determine the time periods during which you will program
thetemperatures youhavejustselected.Youmustprogram
four periods for each day (periods 1, 2, 3, and 4). However,
youmayusethesame heatingandcoolingtemperaturesfor
consecutive time periods. Also keep in mind that, for any
given day, you can only program one set of times for both
heating and cooling (for example, if you select 5:00 AM to
begin heating period 1 on Monday, then your cooling period
1forMonday will alsobeginat 5:00 AM).However,you may
select different time periods for each day separately (for
example, heating/cooling period 1 on Monday may begin at
5:00 AM, but heating/cooling period 1 on Saturday may
beginat9:00AM).Usethetableonthefollowingpagetoplan

* You may only program heating temperatures you have selected into the heating
program and cooling temperatures into the cooling program (for example, you
cannot program the COOL 1 temperature into your heating program). You may
program the temperatures you choose in any order, and you may use the same
temperature in consecutive program periods (for example, you may program
period 1 with temperature 1 and periods 2, 3, and 4 with temperature 2). You do
not have to use all possible temperature choices (for example, you may want to
select temperatures for HEAT 1 and HEAT 2 only – in this case, the HEAT 3 and
