Differential Filtration Controller
INTRODUCTION
General
The Baccara Differential Filtration Controller combines a Controller and a Differential Pressure Sensor (DP).
The Controller has seven wires; four wires for valves, and a molded 3 wire cable with connector for the DP switch.
The G75-DFC operates up to three G75 4
Ω
latch two-wires solenoids, and has a display screen that shows the actual
differential pressure (DIF) and the pressure SET point.
The Flushing Cycle (FC) begins when the DIF reading is greater than or equal to the SET value.
Display:
The LCD display shows:
• The actual differential pressure - DIF
• The pressure set point - SET
• The flushing cycles counter - FC
• While in flushing, a Faucet icon appeases on screen
• When the battery needs replacing, a Low Battery icon appears on screen
