Shaded area represents
full operating range.
In Zone Valve - Constant pressure
mode, the circulator maintains a
constant pressure differential (∆p-
c) in the system as heating load
increases or decreases. Selection
options are Medium or High. See
chart to left for equivalent 00 model
at each setting.
ZONE CIRC - Fixed speed mode
allows the installer to fine tune the
circulator flow rate to precisely match
design load conditions. It is infinitely
variable between MIN/MAX settings.
See chart to left for equivalent 00
model at each variable speed setting.
