The WEB-VA423B24N controller is part of the
Honeywell WEBs Spyder Model 5 family. The
Honeywell Spyder Model 5 (WEB- VA423B24N)
family of unitary controllers provide flexible, freely
programmable, demand-led control that delivers
tangible benefits to reduce energy spends while
driving new levels of functionality and efficiency in
today's buildings. These scalable and freely
programmable BACnet MS/TP-based unitary
controllers utilize smart engineering and
commissioning tools and Sylk™ bus technology.
Multiple flexible configurations can be achieved to
address specific applications.
WEB-VA423B24N and replacement parts are
described in Table 1 and Table 2 on pg.2.
