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 life span.

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.

System Operation
Indicators:

delay feature is active
if ON is ashing. The
compressor will not
turn on until the 5
minute delay has
elapsed.

Low Battery Indicator:

Replace batteries when
indicator is shown.

room temperature.

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.

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.

Technician Setup Technician Setup

This thermostat has 4 dierent setup congurations. To setup the
thermostat for your particular application:

1. Select COOL, HEAT, EmH, or OFF with the system switch.

2. Press and hold the + and - buttons together for 3 seconds. This
3 second delay is deigned so that homeowners do not accidentally
access the installer settings.

3. Use the + and - to change settings. Note: When you want to exit
the Technician Setup options select OFF using the system switch.

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. Default setting is ON. Selecting OFF with the jumper pin will remove this
delay.

Tech Settings

O

This feature allows the installer
to change the calibration of the
room temperature display. For
example, if the thermostat reads
70 degrees and you would like it
to read 72 then select +2.

The swing setting often called
“cycle rate”, “dierential” or
“anticipation” is adjustable. A
smaller swing setting will cause
more frequent cycles and a larger
swing setting will cause fewer
cycles.

The cooling swing setting
is adjustable from 0.2˚ to
2˚. For example: A swing
setting of 0.5˚will turn the
cooling on at approximately

0.5˚ above the setpoint
and turn the cooling o at
approximately 0.5˚ below
the setpoint.
