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.

correctly positioned, remove the battery, then  
use a pencil or small screwdriver to move the

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.

ture settings.  
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,  
answer questions 5 through 8.  
FOR COMMERCIAL APPLICATIONS:  
1a. What time does the first person arrive at the  
building in the morning?  
b. What temperature should the building be at  
this time? (heating? cooling?) These will be  
your MOR (morning) temperature settings.  
4a. What time does the building become vacant?  
b. What temperature should the building be at  
this time? These will be your NHT (night)  
temperature settings.  
IN YOUR HOME:  
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.

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.  
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

theprogrammedfan, press  
untilFAN  
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  
href="
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  
than 68°F). If such a conflict exists, you must  
set the lowest cooling temperature higher in
