The BAC-8001-36 is congured for single duct cooling VAV control without reheat. Connect the controller as shown in the Figure
Cooling or heang applicaon drawing as below. A BAC-8005-36 may also be used for this applicaon.
For cooling and heang, a duct temperature sensor is required for Discharge Air Temperature liming and automac changeover.
See the topic Advanced opons on page 21 for instrucons to enable Discharge Air Temperature liming.
