PRECAUTIONS
This thermostat is intended for use with a low voltage NEC
Class II system. Do not use this thermostat with a line voltage
system. If in doubt about whether your wiring is millivolt, line,
or low voltage, have it inspected by a qualifi ed heating and air
conditioning contractor or electrician.
Do not exceed the specifi cation 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 components could
cause the control to malfunction.
CAUTION
!
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 specifi ed voltage.
Higher voltage will damage control and could cause
shock or fi re hazard.
Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will damage
thermostat and could cause personal injury and/or
property damage.
Thermostat installation and all components of the
system shall conform to Class II (current limited)
circuits per the NEC code. Failure to do so could cause
a fi re hazard.

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 thermostat has a wall mounting plate, remove the
thermostat 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.
ATTENTION!
This product does not contain mercury. However, this product
may replace a unit which contains mercury.
Do not open mercury cells. If a cell becomes damaged, do
not touch any spilled mercury. Wearing nonabsorbent gloves,
take up the spilled mercury and place into a container which
can be sealed. If a cell becomes damaged, the unit should be
discarded.
Mercury must not be discarded in household trash. When the
unit this product is replacing is to be discarded, place in a
suitable container. Refer to www.white-rodgers.com for location
to send the product containing mercury.

GAS / ELEC SWITCH
If your system is a heat pump, the GAS/ELEC Switch must be
set to ELEC (see Fig. 1) If your system is a single stage, the
switch must be set to GAS. The switch setting must agree with
the system confi guration selected in the confi guration menu.
BATTERY LOCATION
ATTACH THERMOSTAT BASE TO WALL
1. Remove the packing material from the thermostat. Gently
pull the cover straight off the base. Forcing or prying on the
thermostat will cause damage to the unit.
2. Place base over hole in wall and mark mounting hole
locations on wall using base as a template (see Fig.1).
3. Move base out of the way. Drill mounting holes.
4. Push wires through opening in thermostat base.
5. Fasten base loosely to wall 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.
6. Connect wires to terminals on base using appropriate
wiring schematic (see fi gs. 2 through 4).
7. Push excess wire into wall and plug hole with a fi re-resistant
material (such as fi berglass insulation) to prevent drafts
from affecting thermostat operation.
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
energized in COOL. If the thermostat you are replacing or the
heat pump being installed with this thermostat requires a “B”
terminal, to energize the changeover relay in HEAT, the O/B
switch must be moved to the “B” position.
“AA” Alkaline Batteries
Two “AA” alkaline batteries are installed in your thermostat
with a battery tag to prevent power drainage. Prior to use,
open the battery door and remove the battery tag. To open,
pull the battery door as shown by the arrow and lift open. The
two “AA” batteries will operate all functions or maintain time
and continuously display the temperature during a loss of AC
power. Installed batteries will also allow programming prior to
installation. To replace batteries, pull the battery door shown
by the arrow and lift open. Using the polarity indicated inside
the battery door, insert the batteries. To close the battery door,
swing the door down while pulling in the direction of arrow.
Once fully down, snap the door back into position.
Thermostat can be powered by system AC power or Battery. If
is displayed, the thermostat is battery powered. If is not
displayed, thermostat is system powered with optional battery
back-up. When battery power remaining is approximately half,
the will be displayed. When “Change ” is displayed,
install fresh “AA” alkaline batteries immediately. For best
results, use new premium brand alkaline batteries such as
Duracell® or Energizer®. We recommend replacing batteries
every 2 years. If the home is going to be unoccupied for an
extended period (over 3 months) and is displayed, the
batteries should be replaced before leaving. When less than
two months of battery life remain, the setpoint temperature will
offset by 10 degrees (10 degrees cooler in Heat mode / 10
degrees warmer in Cool mode). If offset occurs, the normal
setpoint can be manually reset with or . Another offset
will occur within two days if batteries are not replaced. To
replace the batteries, set system to OFF.

INSTALLATION
ENERGY MANAGEMENT RECOVERY
(EMR)
When the EMR feature is activated the thermostat’s
microcomputer calculates the time it will take to change the
room temperature to the next heat or cool program setting.
Then the thermostat will start the system before the next
programmed period so that the desired temperature is reached
at or near the beginning of the period (the thermostat calculates
15 minutes for every 1°F temperature change). This feature
provides better effi ciency by allowing gradual temperature
changes.
For example: The thermostat is programmed to provide an
overnight heating temperature of 66°F, and during the next
program period, beginning at 6:00 AM, the programmed
temperature is 70°F. With EMR activated, the thermostat will

automatically start the heating system at 5:00 AM, so that the
programmed temperature of 70°F is reached by about 6:00
AM.
If the overnight room temperature drops only to 68°F, the
thermostat will start the system at 5:30 to reach the programmed
temperature of 70°F at 6:00.
The thermostat is shipped with the EMR feature active, which
means that the thermostat will start the heating system before
the beginning of the next program period.
To deactivate the EMR function, see the Confi guration menu
on Page 5). The thermostat will then wait until the programmed
time to start the system for a temperature change.

THERMOSTAT QUICK REFERENCE
Before you begin programming your thermostat, you should be
familiar with its features and with the display and the location
and operation of the thermostat buttons and switches (see
fi g. 5). Your thermostat consists of two parts: the thermostat
cover and the base. To remove the cover, pull it straight out
from the base. To replace the cover, line up the cover with the
base and press until the cover snaps onto the base.
