Fixed Speed Mode

Fine tune the circulator flow rate to precisely match design load conditions. It is infinitely variable between min/max settings.

Constant Pressure Mode

The circulator maintains a constant pressure differential in the system as the heating load increases or decreases.

Proportional Pressure Mode

Maintains a proportional pressure differential in the system as heating load increases or decreases. Flow will change in relationship to the change in pressure differential.

The best option for panel radiators with TRV's.
