Chapter 6 Applications for the 1 heat/1 cool configuration
38 CNT-SVX06B-EN
Binary outputs for 1 heat/1 cool
applications
This configuration supports fan coil and cabinet heater applications, with
the following components:
• Supply fan with up to three speeds
• Main hydronic coil with a 2-position control valve (optional)
• Hydronic heating coil with a 2-position control valve or single-stage
electric heat (both optional)
• Two-position outdoor air ventilation damper (optional)
The Tracer ZN511 controller includes five binary outputs. Each binary
output is a relay with a rating of 12 VA. Table 10 describes the function of
each output for 1 heat/1 cool applications.
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.
