The CHEMTROL® 230 ORP Controller is a simple, easy to use controller designed to monitor and maintain the Oxidation-Reduction Potential (ORP or Redox) of neutral-type sanitizers - such as bromine or dichlor - that do not require pH control.
SANITIZER CONTROL MADE EASY
The CHEMTROL® 230 is a microprocessor-based digital controller designed to maintain the sanitizer ORP (oxidation-reduction potential or Redox) level in high-end residential pools, small commercial pools and spas and light industrial applications.

The bright LCD display shows ORP readings, calibration adjustments and alarm limits. The five LED lights indicate the operating mode (OFF, Manual or Auto), feed status, out-of-range alarms and overfeed alarms.
The front panel controls include setpoint, calibration, low and high alarm limits, safety timer limit and proportional feed adjustment.
Feed control is either ON/OFF or Proportional. The Proportional Feed feature is particularly useful to avoid overfeeding in small bodies of water. It reduces the feed cycle time progressively as the sensor reading gets closer to the setpoint.
EASY TO INSTALL
Installation of the CHEMTROL® 230 is as easy as 1-2-3.
CONTROLLER - Connect the controller to the 110 or 230V output of the Timer in parallel to the recirculation pump. This will prevent accidental feeding of chemicals when the pump is not running. Make sure to follow the electrical code.
SENSOR - Install the ORP sensor on the recirculation line or on the optional bypass line. The sensor can be mounted directly on the main recirculation line with a 2" PVC tee, as shown on the schematic. For recirculation lines over 2" in diameter lines, the sensor should be mounted on a 1/2" bypass line.
CHEMICAL FEEDER - Connect the chemical feeder to the 110 or 230V controller output, according to the manufacturer's instructions, making sure to inject the chemicals downstream of the sensor. For a bromine or chlorine erosion feeder, install a corrosion-resistant solenoid valve on the intake line of the feeder. The controller is compatible with most ozonators and electrolytic generators.
