• Select the reference page with your
wiring diagram and set-up
information below.
• The C-wire is required to operate
your CT80. If you do not have a
C wire you will need to provide an
alternate source of 24VAC power to
the unit.
• If your combination of wires is
shown here, you can use the wiring
table at the end of the install section
to determine your connections, or
contact customer support for help.
• When handling, take care not to
damage the labels for each wire.
