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.
• COMPUTED ENERGY MANAGEMENT
RECOVERY (EMR) — The thermostat’s
microcomputer automatically calculates the
time it will take to change the temperature to
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
62
°
F, and that during the next program
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.
• 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) to the ON position, if it has not already
been done. To do this, press SYSTEM
HEAT/EMER/OFF/
COOL/AUTO
to turn
thermostat OFF. Then remove the thermo-
stat body from the wall. Check the position
of switch #4 (the last switch on the right). If
it is ON (up), simply put the thermostat back
on the wall. If the switch is OFF (down),
remove the battery, then use a pencil or
