All of our thermostats use the same
universal magnetic badge. Visit the
company website to learn more about
our free private label program.
Gently slide a screwdriver into the
bottom edge of the badge. Gently turn
the screwdriver counter clockwise. The
badge is held on by a magnet in the well
of the battery door. The badge should pry
off easily. DO NOT USE FORCE.
Wall Locations
The thermostat should be installed approximately 4 to 5 feet above the
floor. Select an area with average temperature and good air circulation.
Installation Tip
Pick an installation location that is easy for
the user to access. The temperature of the
location should be representative of the
building.

Important
The low battery indicator is displayed
when the AA battery power is low. If the
user fails to replace the battery within 21
days, the screen will only show the low
battery indicator but maintain all
functionality. If the user fails to replace
the batteries after an additional 21 days
(days 22-42 since first "low battery"
display) the setpoints will change to 55˚F
(Heating) and 85˚F (Cooling). If the user
adjusts the setpoint away from either of
these, it will hold for 4 hours then return
to either 55˚F or 85˚F. After day 63 the
batteries must be replaced immediately to
avoid freezing or overheating because the
thermostat will shut the unit off until the
batteries are changed.
