Built‐In Control Modes∆P‐C (Constant Pressure Differential) Control Mode∆P 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.

In the example above, the pump is set to 2210 rpm. Minimum and Maximum speeds vary depending on pumps models.
Built‐In Control Modes∆P‐V (Variable Pressure Differential) Control Mode∆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 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 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 proportionallyat maximum flow. As the flow decreases, the head decreases proportionally.
