Description
ActiveADAPT
Purple
The activeADAPT program allows the circulator to adapt its performance to the demands of
the system during short control intervals within a defined adjustment area.
• It improves the hydraulic balance of the system
• It ensures optimum performance during partial load periods, e.g. at night
• It enables quick configuration
Orange
Mode C - Constant pressure difference
The circulator maintains a constant head (pressure), regardless of the heat demand from
the system (flow rate)
Green
Mode P - Proportional pressure difference
The hydraulic head (pressure) of the circulator is proportionally reduced as the demand for
heat by the system decreases (reduction of the flow rate) and increases proportionally with
the increase in the demand for heat by the system (increase in flow rate)
Blue
Min-max mode - Fixed speed
The circulator maintains a fixed speed, regardless of the heat demand from the system
(flow rate). The speed is adjusted by gradually positioning the selector at any point between
the min and max positions. If the performances are insufficient, progressively increase the
value or if noises due to the speed of the pumped fluid are established, gradually reduce the
calibration
