Description:

The R&D Specialties Multi-Trol Controller is a microprocessor based controller for commercial and industrial filters, softeners, and DI units. It is ideally suited for controlling stagers, motor valves, and solenoids on any externally valved equipment. The Multi-Trol is a complete system that combines features not previously available in one compact unit.

The Multi-Trol provides up to 24 programmable cycles utilizing a maximum of 24 control relays. Each relay can operate during any or all cycles. Setpoints allow fast and easy adjustment of cycle times and relay outputs. This permits the operating equipment to be fine tuned for optimum performance.

Various switch and analog inputs offer flexibility in the method selected to initiate backwash or regeneration. By utilizing optional R&D sensors to monitor differential pressure, flow, pH or conductivity / resistivity, backwash or regeneration can either be controlled manually or fully automated.

The Multi-Trol's easy-to-read backlit display indicates the system status and all input sensor readings. Single or multiple units can be monitored and controlled using one Multi-Trol controller.

These features allow the Multi-Trol to control a wide variety of equipment with maximum operator control. For special applications, the Multi-Trol can be tailored to meet specific requirements.
