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

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.

This thermostat requires a 24V common
wire to the C terminal.

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.

Operation of the FAN & SYSTEM button when connected to
WIFI and running a programmable schedule from the app:
When the set at temperature is changed while an app schedule is
running, the thermostat will enter a temporary hold, and the Fan and
System buttons change to RUN and HOLD for 15 seconds. If you wish to
enter PERMANENT HOLD press the HOLD button at this time.
If you don’t press the HOLD button when the HOLD icon appears the
thermostat will remain in temporary hold for 4 hours.
When connected to WIFI you may also have the ability to turn

In Auto you have the ability to switch between Auto Heat or Auto Cool
by pressing the system key. This can be done once the current mode has
reached its setpoint. For example: if in Auto Heat, the heat setpoint must
be satised before the thermostat will allow you to switch to Auto Cool.
You can switch out of Auto by holding down the system key. To get back
into Auto, you must toggle the system key to Auto.
