6. Programming your 0034ePlus circulator:
Modify the performance of the circulator as needed by changing the
operating mode using the easy programming button keypad. When the circulator is powered on, the LED will illuminate
and change color based on the operating mode selected. The LED will flash each time a setting is changed.
See diagram below to set pump for desired operating mode. The selection of the right operating curve
depends on the characteristics of the system and the actual flow / head requirements. See Pump Curves to
determine the best operating mode for the system. See cross-reference replacement chart on back page.
The 0034ePlus has 5 Operating Modes:
• activeADAPT™ — Automatic, self-adjusting, proportional pressure, variable speed
(Violet LED)
• Constant Pressure — 5 curve settings of constant pressure, variable speed
(Orange LED)
• Proportional Pressure — 5 curve settings of proportional pressure, variable speed
(Green LED)
• Fixed Speed — Variable fixed speed settings (1 - 100%)
(Blue LED)
• 0-10V DC — Analog external input or PWM pulse width modulation
input from building control system, variable speed
(Yellow LED)
