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 rst“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 o until the
batteries are changed.
Important
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

About The Badge
All of our thermostats use the same
universal magnetic badge. Visit the
company website to learn more about
our free private label program.

Subbase Installation
The thermostat should be installed approximately 4 to 5 feet above the
oor. Select an area with average temperature and good air circulation.
• Close to hot or cold air ducts
• That are in direct sunlight
• With an outside wall behind
the thermostat
• In areas that do not require
conditioning
• Where there are dead spots
or drafts
(in corners or behind doors)
• Where there might be
concealed chimneys or
pipes

Horizontal Mount
For vertical mount put one screw on the top
and one screw on the bottom.
For horizontal mount put one screw on the
left and one screw on the right.
All of our products are mercury free.
However, if the product you are
replacing contains mercury, dispose of
it properly. Your local waste

Wiring Tips
RH & RC Terminals
For single transformer systems, leave the
jumper wire in place between RH and RC.
Remove jumper wire for two transformer
systems.
Heat Pump Systems
If wiring to a heat pump, use a small
piece of wire (not supplied) to connect
terminals W and Y.
(With NO AUX or
Emergency Heat)
C Terminal
The C (common wire) terminal does
not have to be connected when the
thermostat is powered by batteries.
Wire Specications
Use shielded or non-shielded
18-22 gauge thermostat wire.
Caution:
Electrical Hazard
All components of the control
system and the thermostat
installation must conform to Class
II circuits per the NEC Code.
Warning:
Installation Tip: Do not overtighten terminal block screws, as this
can damage the terminal block. A damaged terminal block can
keep the thermostat from tting on the subbase correctly or cause
system operation issues. Max Torque = 6in-lbs.
Wiring
If you are replacing a thermostat,
make note of the terminal
connections on the thermostat
that is being replaced. In some
cases the wiring connections will
not be color coded. For example,
the green wire may not be
connected to the Gterminal.
Loosen the terminal block
screws. Insert wires then
retighten terminal block screws.
Place nonammable insulation
into wall opening to prevent
drafts.

This feature allows the installer to
select the minimum run time for
the compressor. For example: a
setting of 4 will force the
compressor to run for at least 4
minutes every time the
compressor turns on, regardless of
the room temperature.
You can select the minimum
compressor run time from“o”,
“3”,“4”, or “5”minutes. If 3,4,
or 5 is selected, the compressor
will run for at least the selected
time before turning o.
