period, beginning at 6:00 AM, you have

programmed a temperature of 70°F. The

thermostat will automatically activate the

heating system at about 5:00 AM, so that

the programmed 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 informa-

tion to learn about the many features of the

thermostat.

• AUTOMATIC CHANGEOVER — You can

set the thermostat to automatically switch

the system from heating to cooling as

needed. First you must move option switch

#4 (located on the back of the thermostat

body)totheONposition, ifithasnotalready

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 #4 (the last switch on the

right). If it is ON (up), simply put the thermo-

stat back on the wall and restore 24v AC

power. If the switch is OFF (down), remove

• COMPUTED ENERGY MANAGEMENT

RECOVERY (EMR) — The thermostat’s

microcomputerautomaticallycalculatesthe

the next program setting. Then the thermo-

stat will activate the heating or cooling sys-

tem to change the temperature so that the

desired temperature is reached at the be-

ginning of the next program period. As an

example of this feature, assume that you

have programmed your thermostat to pro-

vide an overnight heating temperature of

allow the temperature separation between

the highest heat setting and the lowest cool

setting to be less than 1°F. For example, if

the highest heat setting is 75°F, the lowest

cool setting cannot be below 77°F (see

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.

PLANNING FOR YOUR NEEDS

First, answer the following questionsto help you

decide what your needs are. If you are using the

thermostatforacommercialapplication(astore,

officebuilding,etc.),answerquestions1through

4. If you are using the thermostat in your home,

answer questions 5 through 8.

For maximum comfort and efficiency, keep the

following guidelines in mind when planning your

program.

• When heating (cooling) your building, pro-

gramthetemperaturestobecooler(warmer)

when the building is vacant or during peri-

ods of low activity.

FOR COMMERCIAL APPLICATIONS:

1a. What time does the first person arrive at the

building in the morning?

• During early morning hours, the need for

cooling is usually minimal.

b. What temperature should the building be at

this time? (heating? cooling?)

2a. What time do the building occupants reach 6a. What time does the last person leave the

for each day separately (for example, heat-

ing/cooling period 1 on Monday may begin

at 5:00 AM, but heating/cooling period 1 on

Saturday may begin at 9:00 AM). Use the

following table to plan your program time

periods, and the temperatures you want

during each period. You may also want to

look at the sample program table to get an

idea of how the thermostat can be pro-

grammed.

NOTE

To operate properly in the AUTO mode, there

must be a minimum 1°F separation between

the highest heat temperature and the lowest

cool temperature (see diagram below).

4. What happens if the electricity goes off

or is manually shut off?

6. What can cause the thermostat display

to freeze or go blank?

If you have not installed a 9 volt alkaline

battery, the display will go blank and the

program will be lost in five seconds. When

electricity is restored, the thermostat will

maintain a heating temperature of 64°F and

a cooling temperature of 82°F until you

reenter your program. Setpoint tempera-

ture will not be displayed.

A completely blank display may indicate

that power has been lost to the thermostat

and the backup battery is also dead. How-

ever, if there is power to the thermostat and

the display is blank or frozen, static dis-

charge is probably the cause.

During periods of low humidity (especially

during cold weather), you may feel or see a

spark discharge when you touch the ther-

mostat. This may cause the program to be

lost or the thermostat to display incorrectly.

To correct this, remove the thermostat from
