INTRODUCTION & SPECIFICATIONS
Congratulations and thank you for your purchase of the H2O Drive®control panel. This manual
explains the features and operations of the controller which was designed to operate one well
pump in a pressure control application. The controller automatically controls the operation and
speed of the pump based on the signal from the pressure transducer.
GENERAL
• One Variable Frequency Drive well pump pressure controller
• Operates using a 0-150 PSI pressure transducer (4-20mA)
• HMI - Rotary selector for menu navigation and editing settings
• HMI - High-Brightness 2.4” color graphic LCD display, 240X320 pixel resolution
PUMP CONTROL AND PROTECTION
• Pump run indication
• Pump speed (Hz) and Amps (A) indication
• Pump motor overload protection
• High- and low-pressure alarms
• Pump dry run alarm and well recharge timer
• Floor water sensor and low level switch alarm/shutdown
SYSTEM
• Pump run time
ELECTRICAL SPECIFICATIONS
• Input voltage: 240V nominal
- 200-240V 50Hz/60Hz, single phase for RD150 & RD300
- 200-240V 50Hz/60Hz, three phase/single phase for RD500
- 200-240V 50Hz/60Hz, three phase for RD750
• Output 0-240V, three phase, 0-60Hz capable of operating up to 80Hz
Note: The output voltage cannot exceed the input voltage.
