CAUTION
!
Remove power from the system at the
circuit breaker/fuse box before removing
or attaching the thermostat body. Equip-
ment damage and/or personal injury could
occur.

If the word BATTERY is flashing in the display
window, the batteries are low and should be
replaced with fresh "AA" Energizer® alkaline
batteries.
PARTS OF THE THERMOSTAT
The Back of The Thermostat Body
Turn the thermostat body over. On the back are
the 3 "AA" Energizer® alkaline batteries and the
two option switch groups (A and B).
CAUTION
!
Before removing thermostat from the wall
to replace the batteries, remove 24vAC
power from the thermostat at the breaker/
fuse box.
1. The"AA"Energizer® alkalinebatteriesprovide
power to the thermostat when the 24vAC
power is interrupted (for example, when you
remove the thermostat from the wall for pro-
gramming). Fresh batteries will maintain the
stored program for approximately a year. If
power loss is long enough for the program to
be lost, the thermostat will automatically re-
turn to the factory programmed temperatures
(64°F heating and 82°F cooling) when power
is restored. You must reprogram the thermo-
stat if this happens.
2. You may adjust the option switches for EMR,
keypadlockout,andautomaticchangeoverfrom
heat to cool (see OPERATING FEATURES).

The thermostat will automatically activate the
heating system at 5:00 AM, so that the pro-
grammed 70°F temperature is reached by
about 6:00 AM.
OPERATING FEATURES
Now that you are familiar with the thermostat
display and buttons, read the following information
to learn about the many features of the thermostat.
This feature is controlled by Group B option
switch #3. To enable the EMR function, first
you must move option switch #3 (located on
the back of the thermostat body) to the OFF
position, if it has not already been done. To do
this, turn off 24v AC power to the thermostat.
Then remove the thermostat body from the
wall. Check the position of switch #3 (the last
switch on the right). If it is OFF (down), simply
put the thermostat back on the wall and re-
store 24v AC power. If the switch is ON (up),
remove the battery, then use a pencil or small
screwdriver to move the switch to the OFF
position (see figure below). Leave the battery
out of the thermostat for at least two minutes,
to allow the thermostat to reset itself. See
• COMPUTED ENERGY MANAGEMENT RE-
COVERY (EMR) — The thermostat’s micro-
computercanbesettoautomaticallycalculate
the time it will take to change the temperature
to the next program setting. Then the thermo-
stat will activate the heating or cooling system
to change the temperature so that the desired
temperature is reached at the beginning of the
next program period. As an example of this
feature, assume that you have programmed
your thermostat to provide an overnight heat-
ing temperature of 62°F, and that during the
next program period, beginning at 6:00 AM,
you have programmed a temperature of 70°F.

PROGRAMMING YOUR THERMOSTAT
Now you are ready to program your thermostat.
This section will help you plan your thermostat's
program to meet your needs.
• When heating (cooling) your building, pro-
gram the temperatures to be cooler (warmer)
when the building is vacant or during periods
of low activity.
For maximum comfort and efficiency, keep the
following guidelines in mind when planning your
program.
• During early morning hours, the need for cool-
ing is usually minimal.

3a. What time do the building occupants reach a
minimum activity level (limited personnel in
building)?
b. What temperature should the building be at
this time? These will be your EVE (evening)
temperature settings.
PLANNING FOR YOUR NEEDS
First, answer the following questions to help you
decide what your needs are. If you are using the
thermostat for a commercial application (a store,
officebuilding,etc.),answerquestions1through4.
If you are using the thermostat in your home, 4a. What time does the building become vacant?
answer questions 5 through 8.
b. What temperature should the building be at
this time? These will be your NHT (night)
temperature settings.
FOR COMMERCIAL APPLICATIONS:
1a. What time does the first person arrive at the
building in the morning?
IN YOUR HOME:
b. What temperature should the building be at
this time? (heating? cooling?) These will be
your MOR (morning) temperature settings.
2a. What time do the building occupants reach a
maximum activity level (using lights, equip-
ment, meeting rooms, etc.)?
5a. What time does the first person get up in the
morning?
b. What temperature should the house be at this
time? These will be your MOR (morning)
temperature settings.
6a. What time does the last person leave the
house in the morning?
b. What temperature should the building be at
this time? These will be your DAY tempera-
ture settings.

2. Determine the time periods during which you
will program the temperatures you have just
selected. You must program four periods for
each day (periods 1, 2, 3, and 4). However,
you may use the same heating and cooling
temperatures for 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 1 for Monday will also
begin at 5:00 AM). However, you may choose
*
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 A
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 B and periods 2, 3,
and 4 with temperature A). You do not have to use all possible
temperature choices (for example, you may want to select
temperatures for HEAT A and HEAT B only – in this case, the
HEAT C and HEAT D temperatures would stay the same as
previously programmed).

4. What happens if the electricity goes off or
is manually shut off?
The thermostat can only be programmed in
the HEAT and COOL modes. See PRO-
GRAMMING YOUR THERMOSTAT.
If you have not installed 3 "AA" alkaline batter-
ies, the display will go blank and the program
willbelostinapproximatelyoneminute. When
electricity is restored, the clock will reset itself
to 12:00 PM (noon) and the thermostat will
maintain a heating temperature of 64°F and a
cooling temperature of 82°F until you reenter
your program. Setpoint temperature will not
be displayed.
If fresh "AA" Energizer® alkaline batteries are
installed, the program will be maintained for
about one year with no 24vAC power present
to the thermostat. See OPERATING YOUR
THERMOSTAT.

AUTO is displayed. To change the program-
ming, see PROGRAMMING YOUR THER-
MOSTAT.
7. What can cause the thermostat display to
freeze or go blank?
A completely blank display may indicate that
power has been lost to the thermostat and the
backup battery is also dead. However, if there
is power to the thermostat and the display is
blank or frozen, static discharge is probably
the cause.
5. Why can’t I program the thermostat in the
AUTO mode?
34
During periods of low humidity (especially
during cold weather), you may feel or see a
spark discharge when you touch the thermo-
stat. This may cause the program to be lost or
the thermostat to display incorrectly. To cor-
rect this, remove the thermostat from the wall
and disconnect the battery. Wait about two
minutes, then reconnect the battery. The
thermostat will revert to the factory preset

you don’t want to reprogram the thermostat
To prevent further static discharge problems,
touch another object to release static build-up
before touching the thermostat. See OPER-
ATING YOUR THERMOSTAT.
8. Why won’t the setpoint temperature go to
the temperature I want?
IntheAUTOmode,thehighestheatingsetpoint
temperature you select must be at least 1°F
lower than the lowest cooling setpoint tem-
perature you select (for example, if 70°F is
yourlowestselectedcoolingtemperature,you
cannotselectaheatingtemperatureanyhigher

set the lowest cooling temperature higher in
