Wire the Indoor Unit for Quantum Ultra Ducted Ceiling Concealed (RYT-24) SystemsUpdated 13 days ago
Introduction
This article explains how to wire the indoor unit for Quantum Ultra Ducted Ceiling Concealed (RYT-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. 
Indoor Unit Wiring
Open the electrical junction box to access the wiring terminals. Ensure that all connecting wires are routed through the wire-inlet rubber grommet to maintain a proper seal.
Connect the wires in accordance with the wiring diagram, then verify that all wire strands are fully inserted and securely clamped at the terminals. All connections must be tight and free of looseness.
