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 optional if thermostat is
hardwired (R and C terminal connected to 24V
power).
Important:
High quality alkaline batteries are recommended.
Rechargeable batteries or low quality batteries
do not guarantee a 1-year life span.
Insert 2 AA
Alkaline batteries
(included). High
quality alkaline
batteries are
recommended.

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.
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.

Fan Operation Setup
Electric: The thermostat
operation jumper pin
should be put in the ELEC
position. This setting
allows the thermostat to
operate the fan during a
call for heat. Most PTAC
systems will require ELEC
Fan Operation Setup.
Important
The RESET button must be pressed after changing any switch or
jumper pin setting. Batteries must be installed for this operation.
Room
Temperature
Calibration
This feature allows the installer
to change the calibration of the
room temperature display. For
example, if the thermostat reads
70˚ and you would like it to read
72˚ then select +2.
0˚F
You can adjust the room
temperature display to read
up to 4˚above or below the
factory calibrated reading.
CA
Caution:
Electrical Hazard
All components of the control
system and the thermostat
installation must conform to Class
II circuits per the NEC Code.
Warning:
Failure to disconnect the power
before beginning to install this
product can cause electrical
shock or equipment damage.
Wiring Tips
C Terminal
The C (common wire) terminal does
not have to be connected when the
thermostat is powered by batteries.

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.
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 red
wire may not be connected to the
Rterminal.
Loosen the terminal block screws.
Insert wires then retighten terminal
block screws.

This thermostat is shipped from the factory to operate a conventional
heating and cooling system. This thermostat will also operate a heat
pump system. See the “heat pump”conguration step on page 10 of
this manual to congure the thermostat for heat pump applications.
Gas: For systems that
control the fan during
a call for heat, put the
jumper pin into the GAS
position.
Fahrenheit/Celsius Display
Select F or C with the jumper pin to select desired display.
Compressor Short Cycle Delay
The compressor short cycle delay protects the
compressor from short cycling. This feature will not allow the compressor to
be turned on for 5 minutes after it was last turned o.
Using the jumper on the back of the thermostat, selecting ON will not allow
the compressor to be turned on for 5 minutes after the last time the
compressor was on. Selecting OFF will remove this delay.

Most PTAC systems support two speed fan operation. In a single speed
fan PTAC system or conventional single speed fan system, a jumper
should be installed between GL and GH on the thermostat.
Note:
The swing setting, often called
“cycle rate”,“dierential or
“anticipation”is adjustable. A
smaller swing setting will cause
more frequent cucles and a larger
swing setting will cause fewer
cycles.
The heating swing setting is
adjustable from 0.2˚ to 2˚. For
example: A swing setting of
0.5˚ will turn the heating on at
approimately 0.5˚ below the
setpoint and turn the heating
o at approximately 0.5˚ above
the setpoint.

The second stage of Heat will turn on at 2x the swing setting. The second
stage will turn o when 1x the swing is reached. For example, if the swing
setting is 0.8˚ for heating and the thermostat is set at 70˚ F, the rst stage will
turn on at approximately 69.2˚ F. The second stage will turn on at 68.4˚F and the
rst will turn o at 70.8˚ F.
