EMR causes the thermostat to start
operating the system early in order to
make the building temperature reach
your program setpoint at the time you
specify. In heating, the thermostat will
start 5 minutes early for every 1°F
difference between the room tempera-
ture and the next programmed
temperature. In cooling, the thermostat
uses 15 minutes per °F.

EXAMPLE: If the temperature in the
room is 65°F and the thermostat is
programmed for 70°F at 7 AM, the
thermostat will start approximately 25
minutes early. The difference between
the room temperature (65°F) and the
setpoint (70°F) is 5°. 5° X 5 minutes
per °F = 25 minutes. The setpoint on
the display will actually change to
display 70° about 25 minutes early.

The maximum time the thermostat can
start early in heating is 75 minutes.
The maximum time the thermostat can
start early in cooling is 3 hours and 45
minutes. Cooling can start earlier
because it takes longer for cooling
systems to reach the desired tempera-
ture.

is
displayed on the screen.
Pressing the
and
buttons
at the same time will change the
setpoint temperature displayed to the
setpoint temperature displayed to the
setpoint of the other mode. This will
allow you to modify both the HEAT
and COOL setpoints to accommodate a
HOLD condition while in Automatic
Changeover mode. To adjust, refer to
the Configuration section (page18,
step 7).

The room temperature display can be
adjusted to read higher or lower by
following the configuration menu and
adjusting the temperature to a higher
or lower value. The thermostat is
calibrated at the factory to display a
very accurate room temperature, but
due to various conditions and/or
personal preference, you may wish to
adjust the thermostat display higher or
lower (up to 5°F). For example, if the
thermostat displays a room tempera-
ture of 70° but you want it to display
adjusted to read higher or lower by
following the configuration menu and
adjusting the temperature to a higher
or lower value. The thermostat is
calibrated at the factory to display a
very accurate room temperature, but
due to various conditions and/or
