What wires do you have?
Make sure your wires are labeled. This may require you to find the ‘other end’ connection for each
wire on your heating or air conditioning equipment and read the label there. Refer to the Wire
Reference page at end of install section for better understanding of
wire labels from different HVAC system makers.
IMPORTANT:
The CT80 requires constant 24VAC power from the
HVAC system’s “C wire”. If you do not have a C wire you can run a new
wire from the HVAC or use a standard 24VAC 100mA or greater wall
transformer.
IMPORTANT:
If you have both RH and RC wires you need to move
the RC/RH switch to the UP position which separates these terminals.
Prepare Wires
Please follow these guidelines for safe and secure wire connections:
• You will need at least 2.6” of wire for each of your connections to the CT80.
• If you do not have enough wire, splice additional wire to allow enough slack.
•
Terminals accept wires from 16-22awg.
• Fan out wires below the hole as shown.
• Remove insulation 1/8” from the tip of each wire.
