Additional components

The following components are required for proper equipment operation.
They are not included with the Tracer ZN517 unitary controller. Addi-
tional components may also be required besides those described in this
section, depending on your application.

Power transformer

A transformer providing 24 Vac is required to power the Tracer ZN517
unitary controller and associated output relays and valve and damper
actuators (see "AC power wiring" on page 85).

Zone temperature sensors

Table 2 shows some of the Trane zone temperature sensors that are sup-
ported by the Tracer ZN517 unitary controller. Contact your Trane sales
office for information about other compatible zone sensors.

Discharge air temperature sensors

Discharge air temperature sensors must be Trane 10 kΩ (at 25°C) ther-
mistors. The discharge air temperature (DAT) input may use a sealed
temperature sensor (part number 4190 1100) or a duct/immersion tem-
perature sensor (part number 4190 1103).

Damper actuators (optional)

Actuators cannot exceed 12 VA draw at 24 Vac. Use actuators with on/off
action and spring return (to normally open or closed position), based on
the desired default position.
