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,

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.)?

b. What temperature should the building be at

this time? These will be your DAY tempera-

ture settings.

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 house be at this

time? These will be your DAY temperature

settings.

7a. What time does the first person arrive home in

the evening?

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.

6. Why is the fan running constantly, regard-

less of system operation?

You have programmed the fan to run continu-

ously during this program period. To override

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?

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

programuntilyoureprogramthethermostat. If

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
