Installation Overview

Once you have everything you need, let’s get started!

Thermostat Installation

Turn OFF power

Turn oﬀ all power to your

HVAC (Heating, Ventilation,

and Air Conditioning) system

by using the master

equipment switch or

circuit breaker box.

Conﬁrm that your system is oﬀ

One way to do this is to try to adjust the temperature on

your old thermostat. If you don’t hear the system turn on

within 5 minutes, air does not come out from the vents

or the old thermostat does not even power on, then you

have successfully turned oﬀ the power to your system.

Step 1 Step 2

Make sure your

old thermostat

Does Not Contain

Line Voltage Wiring

If you see any of these wire nuts,

unfortunately the BCC100 may not

work with your system. If you are

unsure or would like to discuss your

options, please contact a professional

or our support line: 1-800-283-3787.

Step 3

WARNING: Failure to turn oﬀ the power may

result in electrical shock and/or damage to the

equipment.

Remove the old thermostat from the

old wall plate

Take a picture of the existing wiring

Make sure that you can clearly read the terminal labels and

see which wires are connected to which terminals from your

photo. You will need to reference this

photo later during the initial setup.

Note: You can also use the wire labels

we have provided you to correctly

label each wire based on the terminal

where it is connected.

Step 4

Conﬁrm you have a C-wire connected

to your old thermostat wall plate

If you do not have a C-wire connected to your old

thermostat, please contact a professional or our support

line for further assistance to determine if the BCC100

Thermostat is compatible with your system.

Disconnect the wires from the old thermostat and

remove the wall plate using a screwdriver

Some thermostats will also require you to use a screwdriver to

disconnect the wires. After the wires are disconnected and

the wall plate removed, we recommend wrapping a pen or

pencil around the wires to prevent them from falling back into

the wall.

Step 6

Step 7

Pull thermostat wires through the hole in the center

of the BCC100 wall plate and mark the location of

the mounting screws

It is recommended to use the BCC100 Wall Plate as a reference

guide to mark the mounting holes and ensure that

all holes and unpainted

surfaces are covered.

Drill and insert wall anchors (if necessary)

Drill two 7/32” holes where you marked the location of the

mounting screws and then insert the wall anchors provided

into these mounting holes.

Check if the wall plate is level and insert screws

Make sure your new BCC100 wall plate is level and insert the

included screws from the package. Mount your new wall plate

to the wall using a Phillips head screw driver.

Step 8 Insert each wire into the corresponding

terminal and close each terminal using a

ﬂat head screw driver

Use the image you took with your

smartphone of your old thermostat wiring

or the wire labels as a reference for where

to place each wire. Be sure that you insert

each wire, one by one, and then

immediately close the terminal and conﬁrm

that the wire is secure inside the terminal

before moving to the next wire. Repeat this

process for each wire to be installed. If you

are unsure of the terminal names on the

BCC100 Wall Plate, refer to BCC100

Terminal Key on the next page.
