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.

Input source
Terminals: GND, 24 V
Terminals: ZN, GND
or communicated
Terminals: AI1
Terminals: BI4 and V4
(BI5 and V5 for two-
compressor units only)
(If these terminals are
not used, the factory-
