Figure 7: Existing EZ Zone Master Controller Sensor Wiring

The EZ Zone Master Controller sensor connec-

tions are located on the right side of the board.

Only a supply air temperature sensor and the

bypass actuator feedback are connected here.

The Auto-Zone Zone Manager includes termi-

nals for connecting the following sensors:

• Supply Air Temperature

• Return Air Temperature

• Outside Air Temperature

The terminals are marked SAT, RAT, and OAT

for ease of wiring. Auxiliary input terminals

AUX1, AUX2 and AUX3 are used for Econo-

mizer Disable, Dirty Filter Alarm and Forced

Occupied Mode. Bypass damper feedback has

been relocated (see next page).
