Description

The Crystal Quest C-100 Controller is an economical monitoring and control solution designed for light commercial reverse osmosis systems.

It helps manage key RO system functions, including pump operation, inlet valve control, membrane flushing, pressure switch monitoring, storage tank level monitoring, pretreatment lockout, and water quality status.

The controller provides relays for the RO pump, inlet solenoid valve, and membrane flush solenoid valve. Dry contact switch inputs monitor the storage tank level, low-pressure switch signal, high-pressure switch signal, and system lockout for pretreatment backwash or regeneration during on/off operation.

All inputs and outputs are controlled with time delays to support proper system operation. This helps coordinate pump, valve, flush, pressure, and tank-level signals for compatible RO system applications.

The C-100 Controller also includes a TDS monitor with sensor rated for a 0–1000 PPM range. The TDS value includes a field-adjustable set point for setting the water quality threshold. If the threshold is exceeded, the controller can produce a system warning to help users monitor RO membrane performance and overall water quality.
