Factory-Provided Sensors
A discharge temperature sensor (VELSEN-0021) will be
factory-provided for field installation in the supply duct.
Refer to Figure 50, p. 69 for installation instructions.
If space control is selected, a combination space
temperature/humidity sensor (BAYSENS036A) will be
factory-provided for field installation in the space. Refer to
Figure 51, p. 70 for installation instructions.
If multi-zone VAV control is selected, a static pressure
sensor (VELCON-0350) will be factory-provided for field
installation in the supply duct or space. Refer to Figure 53,
p. 72 for installation instructions.
If modulating OA/RA dampers w/economizer and an
exhaust fan are selected, a duct static pressure sensor
