Connected Solution for 24VAC Thermostat Systems

Getting Started
The BCC100 thermostat is designed to work on most 24VAC
low voltage heating and cooling systems such as gas and oil
furnaces, heat pumps, and single or dual-stage systems.
Professional installation recommended for:
▶Humidifiers and dehumidifiers
Before removing the wires from the old thermostat, take a
picture of the wiring configuration for reference, and then
label each wire according to the terminal codes using the
wire labels provided.
Remove the Old Thermostat
1
NOTE: After labeling the wires, secure them to an
object such as a pen or clip to prevent them from
falling back into the wall.
WARNING: Turn Off Power
Failure to turn off power may result in
electrical shock and/or system damage.
Disconnect the wires from the old thermostat one by
one. Do not let wires fall back into the wall.
Turn Off Power
Please turn off the unit’s main power at the circuit panel
before beginning the installation process.

3
Feed all wires vertically into the hole or slit in the center
of the backplate. Referencing the photo of the previous
wiring configuration or the wire labels currently on the
wires, insert the wires one-by-one into the matching
terminals, and use the supplied flathead screwdriver to
close each terminal. After you have finished fastening the
wires, pull each wire gently to ensure they are secure.
Repeat this process for each wire to be installed.
Connect the New Wall Plate
3
CAUTION: To prevent possible shorts to adjacent
terminals, use care when securing and routing
your thermostat wires.
Mount the New Wall Plate
Use the enclosed screws and anchors to
mount the new wall plate. In most cases,
you can utilize the same mounting position of your old
thermostat. Be sure to check the alignment of your wall
plate before installation to ensure all holes are covered.
