The Chip Control Box is an economical option for a RO controller available for both the SIMPLX and NRO-440 systems up to 4 membranes. The smaller modular design allows for easier assembly, service and flexibility with a clean and logical layout. It features 6 LED lights to indicate system operation of the RO Unit. The controller removes the need for a low pressure switch to control the pump and a start delay to prevent system cycling. A switching power supply operates on 96-264VAC, automatically adjusting to operating voltage. Voltage at the supply terminals is the voltage for the pump and valves. The controller allows for tank level, system flushing.
