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
12
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
played. Remove the thermostat body from
the wall, turn it over, and check the position
of option switch #3. If the switch is ON (up),
simply put the thermostat back on the wall
