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
Wall Locations
Vertical Mount
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
management authority can give you
instructions on recycling and proper
disposal.
Pick an installation location that is easy for
the user to access. The temperature of the
location should be representative of the
building.

Mount Thermostat
Align the 4 tabs on the subbase with
corresponding slots on the back of the
thermostat, then push gently until the
thermostat snaps in place.
Battery Installation
Battery installation is recommended even if thermostat is hardwired
(C terminal connected). When thermostat is hardwired and batteries
are installed, the thermostat will activate a compressor delay of 5
minutes when the thermostat detects a power outage from the
hardwired power supply.
Important:
High quality alkaline batteries are recommended.
Rechargeable batteries or low quality batteries
do not guarantee a 1-year lifespan.
Insert 2 AA
Alkaline batteries
(included). High
quality alkaline
batteries are
recommended.
Simple
operating
instructions
are found
on the back
of the
battery
door.

LCD
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
Removing The Private
Label Badge
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
o easily. DO NOT USE FORCE.
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.

Caution:
Electrical Hazard
All components of the
control system and the
thermostat installation must
conform to Class II circuits
per the NEC Code.
Warning:
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.
Installation Tip
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 G terminal.
Loosen the terminal block
screws. Insert wires then
retighten terminal block screws.
Place nonammable insulation
into wall opening to prevent
drafts.

Thermostat Wiring Tips
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.
Most PTAC systems support two speed fan operation. In a single speed
fan PTAC system or conventional single speed fan system, the GL terminal
will be used and “I”must be selected in the Technician Setup Menu.
