Section 7: Application Drawings
This section covers the drawings, materials, and instructions for specific VAV applications.
Each EZvav model is designed for a specific set of applications. The following topics are for control technicians and engineers that
will plan for and install controllers for EZvav applications.
Submittal sheets for all of these applications are available from the Resources page at www.nailor.com.

Cooling or Heating without Reheat
The BAC-8001-36 is configured for single duct cooling VAV control without reheat. Connect the controller as shown in the Figure
Cooling or heating application drawing as below. A BAC-8005-36 may also be used for this application.
For cooling and heating, a duct temperature sensor is required for Discharge Air Temperature limiting and automatic changeover.
See the topic Advanced options on page 21 for instructions to enable Discharge Air Temperature limiting.
Submittal sheets for several variations of this application are available from the Resources page at www.nailor.com.
