Identifying Primary And Slave Units - Airstream ITA-6 User Manual

Be sure the communication cable is isolated from all high
voltage sources and fluorescent lights. Do not route the
communication cable and power cables through the same
electrical knockout. Do not run the communication cable next
to power cables. When crossing power cables, cross at 90°.
DO NOT GROUND THE SHIELD WIRE!
DISCONNECT THE POWER SOURCE BEFORE
CONNECTING THE COMMUNICATION CABLE.

Identifying Primary and Slave Units

If your installation requires more than one ITA-6 unit for independent con-
trol of different air inlets, one of the ITA-6 will be configured as the primary
unit and the others will be configured as slaves. Up to 99 slave units can be
connected in this way. When programming the ITA-6, the slave units take
their reference temperature from the primary unit. By default, all units are
set as PRIMARY units.
• Set internal switch #6 to ON for the primary unit or set
it to OFF for a slave unit. If only one ITA-6 unit is used,
set internal switch #6 to ON.
