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

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

tem to change the temperature so that the
desired temperature is reached at the be-
ginning of the next program period. As an

In the AUTO mode, the thermostat will not
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

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)

Also keep in mind that, for any given day,
you can only program one set of times for
bothheatingandcooling(forexample,ifyou
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). How-
ever, youmaychoosedifferenttimeperiods
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
