(actual value) Pumping Head H [F Ft] H 2 H Constant speed pump 1 2. The drive sees the difference between the set value (point 1) and the actual value. (point 2) 3. Via ECM smart technology the controller reduces the speed and reduced the pumping head to match the system curve. (point 3) Q 1 Q 2 Flow Q [USGPM]

7 Built In Control Modes P C C (Constant Pressure Differential) Control Mode On site setting via red button Can be adjusted from 3ft to max pump head Pump will vary the flow but keep a constant diff. pressure Built-in control mode, does not require external sensors Recommended in low resistance systems or in-floor heating loops zoning In the example above, the pump is set to maintain 20 ft constant differential pressure. The flow will modulate from 0 to 230 gpm.

8 Built In Control Modes Constant Speed Control Mode Max Set speed 2210 rpm Min On site setting via red button Can be adjusted from Min to Max speed with 10 rpm increments Built-in control mode, does not require external sensors Recommended in fixed flow/head application In the example above, the pump is set to 2210 rpm. Minimum and Maximum speeds vary depending on pumps models.

9 Built In Control Modes P V (Variable Pressure Differential) Control Mode On site setting via red button Can be adjusted from 3ft to max pump head Pump will automatically vary the flow and the head on system demand. Min head at 0 flow is half the max head set Built-in model, does not require external sensors Recommended in high resistance systems In the example above, the pump is set to maintain 24 ft differential pressure at maximum flow. As the flow decreases, the head decreases proportionally.

10 Built In Control Modes P T T (Temperature Pressure Differential) Control Mode Change in temperature at the pump changes the pressure setpoint IR tool required to activate and set perameters Stratos t installed on return T Max T Min = > or = 50 deg. F T Max: 150 F Max T: 10 T Max: 190 F Max T: 7 T Min: 100 F Max T: 30 T Min: 140 F Max T: 25 Head Head F 150 F Temp 190 F 140 F Temp Condensing Boiler Application Non-Condensing Boiler Application (Decreases delta P on temp rise) (Increases delta P on temp rise)
