Remove the mylar label from the display
window.
INSTALLATION
2All installation is normally performed at
your thermostat.
PROGRAMMING
3You can practice programming before
installing your thermostat by inserting
and connecting the batteries and following
the instructions on page 10.
OPERATION
4YourMaxitrolSelector isdesigned to
operatewith DFM/DFME44 systems only.
TEMPERATURE RANGE
5YourSelectorcan beprogrammed
between 40°F and 95°F (5°C and 35°C).
However, it will display room temperatures
from 32°F to 99°F (0°C and 37°C).
BATTERY WARNING
6When the batteries are low, the “LOW
BATT” indicator on the display will flash.
When this hapens, install new batteries
immediately. Once the “LOW BATT”
indicator appears, the thermostat will
continue to operate for approximately 30
days. (Only alkaline batteries should be
used in your thermostat. Rechargeable
batteries have different properties which
may cause the thermostat to not operate
properly. Do not use old batteries.) The
batteries should last one year.

Programming
CAUTION: The batteries are the only source of power used to
operate your thermostat. If you do not replace the batteries, the
display will dim and your system will operate on the last
programmed temperature or the factory default.
NOTE: If you plan to be away from the premises more than 30
days, we recommend that you replace the old batteries with new
alkaline batteries prior to leaving.

NOTE: Another approach to programming is to first program all weekdays M
through F and SA and SU as same programs. Then, display and change the
programs of only those days which will have different programs.
NOTE: If program time remains 0:00, that particular program will not be
effective; e.g., if Program #2 has time 0:00, the thermostat will jump from
Program #1 to Program #3.
