2.1 Overview
The Relay Panel is a wall mounted low voltage
panel that enables communicating controls to
operate with 24 VAC HVAC equipment. Only three
wires are required from the control to the Relay
Panel.
This Relay Panel controls the operation of heating,
cooling, heat pump and dual fuel systems.
For specific wiring applications, see Field Wiring
Diagrams.
