Chapter 4 Applications for the heat pump configuration

Generic binary output
Binary output 6 is the only output that can be configured as a generic
binary output. When configured as a generic binary output, it can be
monitored only by a BAS, and has no direct effect on Tracer ZN511 opera-
tion.
Overriding binary outputs
The Tracer ZN511 controller includes a manual output test. Use this fea-
ture to manually control the outputs in a defined sequence. For more
information about the manual output test, see “Manual output test” on
page 58.
Wiring requirements and options
Table 6 and Figure 7 on page 23 show required controller inputs for mini-
mal proper operation of all heat pump applications.
Figure 8 on page 24 shows all required and optional components con-
nected for heat pump applications.
