OPERATING FEATURES
Now that you are familiar with the thermostat buttons and
display, read the following information to learn about the many
features of the thermostat.
Energy Management Recovery (EMR) causes the thermo-
stat to start heating early to make the building temperature
reach the program setpoint at the time you specify. Heating
will start 5 minutes early for every 1° of temperature
required to reach setpoint.
• TEMPERATURE OVERRIDE — Press
or
until the
display shows the temperature you want. The thermostat
will override current programming and keep the room
temperature at the selected temperature until the next
program period begins. Then the thermostat will automati-
cally revert to the program.
Example: You select EMR and have your heating pro-
grammed to 65° at night and 70° at 7 AM. If the building
temperature is 65° the difference between 65° and 70° is
5°. Allowing 5 minutes per degree the thermostat setpoint
will change to 70° at 6:35 AM.
• HOLD TEMPERATURE (BYPASSING THE PROGRAM)
The thermostat can hold any temperature within its range
for an indefinite period without reverting to the programmed
temperature. Momentarily press HOLD button. HOLD will
be displayed. Then choose the desired temperature by
5) Select filter replacement run time - The thermostat will
display FLTR after a set time of operation. This is a
reminder to change or clean your air filter. This time can be
set from 0 to 1950 hours in 50 hour increments. A selection
of 000 will cancel this feature. When FLTR is displayed,
you can clear it by pressing HOLD and RUN at the same
time. This resets the timer and starts counting the hours
until the next filter change. Changing the time in the menu
also resets the timer.
