OPERATING FEATURES
Now that you are familiar with the thermostat
display and buttons, read the following infor-
mation 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 tempera-
ture to the next program setting. Then the
thermostat will activate the heating or cool-
ing 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 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, turn off
24 VAC 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 thermostat back on the wall and
restore 24 VAC power. If the switch is OFF
