(User menu, Item 1) The room
temperature display can be adjusted
to read higher or lower by following
the User 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
temperature of 70° but you want it
73°, you can adjust it. To 73° 73°
to display 73° 73°
adjust, refer to the CONFIGURA-
TION section (page 24, item 1).

(User menu, Item 2) 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 multistage heating, the
thermostat will start 8 minutes early
for every 1°F difference between the
room temperature and the next
programmed temperature. In cooling
and heat pump applications, the
thermostat uses 15 minutes per °F.
For heating applications in large
buildings where extra time to reach
the set temperature may be desired,
EMR Long may be selected. When
EMR ON L is selected in the user
menu (page 24, item 2) the thermo-
30
stat 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 approxi-
mately 40 minutes early. The
difference between the room
temperature (65°F) and the setpoint
(70°F) is 5°. 5° X 8 minutes per °F
= 40 minutes. The setpoint on the
display will actually change to
display 70° about 40 minutes early.
The maximum time the thermostat
can start early in heating is 75
minutes (or 3 hours, 45 minutes if
EMR ON L is selected). The
maximum time in cooling and heat
pump applications is 3 hours and 45
minutes. Cooling or heat pump
