Product Installation Guide Installation Tips
Wall Installation
The thermostat should be installed approximately 4 to 5 feet above the oor.
Select an area with average temperature and good air circulation. Pick an
installation location that is easy for the user to access. The temperature of the
location should be representative of the building.
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.
All of our thermostats use the same
universal magnetic badge. Visit the
company website to learn more about
our free private label program.

For vertical mount put one
screw on the top and one screw
on the bottom.
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.
NOTE: To ensure a solid t between
the thermostat and subbase:
1. Mount subbase on a at wall.
2. Use provided screws.
3. Ensure drywall anchors are ush with wall.
4. Push wires into wall.

Replacement Thermostat 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.
1.
2.
3.
This thermostat requires a 24V common
wire to the C terminal.
4.
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.
Failure to disconnect the power
before beginning to install this
product can cause electrical shock or
equipment damage.

Note: Devices such as a oat switch that mechanically break circuits should be installed
so that they break the control wire (Y) not the power (R). Interrupting the power circuit
will shut o power to the thermostat completely and not allow it to operate.
To enter tech setup:
1. Press and hold the + and - buttons for 3 seconds.
2. Press and hold the TECH button.
3. Congure the installer options as desired using the table below. Use the + or - buttons to
