Identifying Primary And Slave Units - Airstream TC5-ITA 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 TC5-ITA unit for independent
control of different air inlets, one of the TC5-ITA 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 TC5-ITA, the
slave units take their reference temperature from the primary unit. By de-
fault, all units are set as PRIMARY units.
• Set internal switch #6 to ON for the primary unit or
OFF for a slave unit. If only one TC5-ITA unit is used,
set internal switch #6 to ON.
