Additional components
The Tracer ZN521 zone controller requires the use of additional components for monitoring and
proper control of the associated equipment. The use of specific components depends on the
application. These components are not included with the Tracer ZN521 zone controller.
Power transformer
Use a UL-listed Class 2 power transformer supplying a nominal 24 Vac (19–30 Vac) to power both
the Tracer ZN521 zone controller (14 VA) and its associated output devices, including relays and
actuators, to a maximum of 12 VA per output utilized.
Water, duct, and outdoor-air temperature sensors
Temperature sensors must be Trane 10 k
Ω
(at 25°C) thermistors. Entering water and discharge air
inputs may use a sealed temperature sensor (part number 4190 1100).
