Chapter 6
Applications for the 1 heat/
1 cool configuration
This chapter provides information about the function of inputs and out-
puts and examples of wiring for typical 1 heat/1 cool applications. The
types of 1 heat/1 cool applications supported by the Tracer ZN511 zone
controller are fan coil units and cabinet heaters as shown in Table 7.
The decision to wire many of the input/output terminals discussed in this
chapter depends on the application. Figure 10 on page 41 through
Figure 14 on page 45 show typical applications that include all required
and all optional components for 1 heat/1 cool applications.
