Figure 9: Existing EZ Zone Bypass Damper Wiring
The EZ Zone Master Con-
troller has two double pole
terminal blocks for the by-
pass actuator connections.
These terminal blocks must
be tied together by an exter-
nal jumper. In addition, the
feedback connection from the
actuator must be terminated
on the other side of the con-
troller .
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
installation. The actuator
“feedback” connection is
now terminated at the same
location as all the connec-
tions. Jumpers are no longer
required since the commons
are tied together within the
circuit board.
