Factory-Provided Sensors

A discharge temperature sensor (VELSEN-0021) will be
factory-provided for field installation in the supply duct. Refer
to Figure 149, p. 108 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
installation instructions.
If multi-zone VAV control is selected, a static pressure sensor
(VELCON-0976) will be factory-provided for field installation in
the supply duct or space. Refer to
installation instructions.
