Wire the Indoor Unit & Decorative Panel for Quantum Ultra Ceiling Cassette (CYT-24) SystemsUpdated 11 days ago
Introduction
This article explains how to wire the indoor unit and decorative panel for Quantum Ultra Ceiling Cassette (CYT-24) systems.
Connect the Signal Cable
There are three terminals (1, 2, 3) and ground (g). It is vital that the colors and numbers between the indoor and outdoor units match for each terminal. The color selection does not matter as much as matching number to number does. Do not mix up the wires between each end.
Consult the diagram affixed to the indoor and outdoor units respectively for specific wiring instructions. 
Wire the Panel
Wire the panel's LED display board and louver swing motor to the indoor unit main control board via 10-pin and 5-pin wires.
