activeADAPT Range
Purple LED
activeADAPT
activeADAPT™ Mode:
activeADAPT is an operating mode
designed for constant circulation systems.
On this setting, the circulator will sense
changes in system flow and head
conditions and adjust the operating
curve automatically. See activeADAPT
operating range in the chart to the right.
Constant Pressure Mode:
At Low setting the circulator will vary speed to
maintain 8 feet of head constant pressure.
At Medium setting the circulator will vary speed
to maintain 16 feet of head constant pressure.
