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 temperature
to the next program setting. Then the ther-

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.
This feature is enabled by option switch #3.
To enable the EMR function, you must
move option switch #3 (located on the back
of the thermostat body) to the ON position.
To do this, press
