The Air Zoning O
ption kit is designed to use the Damper Override “D” terminal signal of the
compressor unit to force open the largest zone while the EarthLinked system is in maintenance mode.
The kit isolates the zone control and air handler power supplies and ensures system performance and
reliability by providing a means of making “R” and “Y” thermostat input of the zone board’s largest
zone. Forcing that zone open relieves excessive static pressure at the air handler.
See Figure 11 for the Field Wiring Diagram of the Air Zoning Option Kit.
