C-100 Reverse Osmosis System Control Panel


Select product option


The Crystal Quest C-100 Controller is an ideal solution for the monitoring and control of light commercial reverse osmosis units. This economical controller provides relays for the RO pump, inlet solenoid valve, and membrane flush solenoid valve.

The dry contact switch inputs monitor storage tank level, low and high-pressure switch signal, and system lockout for pretreatment backwash or regeneration for on/off operation. All inputs and outputs are controlled with time delays for proper operation.

Additionally, the TDS value incorporates a field adjustable set point for the water quality threshold, allowing the unit to produce a system warning if the water quality threshold is exceeded. LED indicates water quality and operating status.
