Operation
Pump Control
• On/Off control using adjustable set point (200 to 900 mV) with adjustable
hysteresis (10 to 100 mV)
• Proportional control using adjustable set point (200 to 900 mV) with
adjustable proportional band (10 to 200 mV)
• Startup delay timer at power-on (0 to 600 sec.)
• Pump flow control 0.5 to 3.5 L/hour (0.13 to 0.92 G/hour) and maximum
output pressure 1 atm (14 psi)
• Manual control for pump priming (defined in setup)
ORP Alarms
