Figure 5: Existing EZ Zone HVAC Wiring

The EZ Zone Master Con-

troller relay outputs consist

of a series of five double pole

terminal blocks. Wire jump-

ers between terminal blocks

are required to the common

of each relay.

The Auto-Zone Zone Man-

ager wiring has been simpli-

fied. There is only one termi-

nal block with connections

clearly marked for ease of in-

stallation. Jumpers are no

longer required since the

commons are tied together

within the circuit board.

Zone Manager wiring is much simpler than the EZ Zone

Master Controller wiring. Be sure to pay strict atten-

tion to all warnings and cautions listed on the sche-

matic.
