JP
This JP jumper configuration will allow the IZAC to
produce 24VAC on output 1 when the relay is energized or
a N/O dry contact between the output and output common,
when J2 is removed.
J1 jumper provides power to the IZAC. With J2 in place
the load uses the same 24VAC that is supplying power to
the IZAC. When J2 is removed, the JP jumper
configuration produces a Normally Open, dry contact
between Output 2 and Output 2 common.
NOTE:
The Output Common will always
be HOT when jumped as shown for
Output 1, with J2 in place and JP's 24
INT jumped to Com.
HOA status LEDs will be ON
when power is applied to the
Output, dry contact will not
light the HOA LEDs.
