display that provides instantaneous updating of all
operating parameters. The unit accepts a modulation
control signal from a BAS varying its output to
meet capacity demand. Models feature a capacity
adjustment of output down to 25 lbs/hr.
The
GSP
uses status lamps on the front to provide
operating diagnostics. The GSP model can accept a
modulating control signal from building management
systems.
