Chemtrol 250 Not Feeding on Auto

Chemtrol - CH230 ORP Digital Chemical Controller

SANITIZER CONTROL MADE EASY

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. A microprocessor-based digital controller, suitable for high-end residential pools, small commercial pools and spas and light industrial applications.

STANDARD FEATURES

All Functions on Front Panel
Adjustable Set-points
Adjustable Alarms
Proportional Feed
Overfeed Safety Timers
Waterproof Cabinet
Easy to install
Simple to use
5-year Electronics Warranty

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 set-point.

CH230 INSTALLATION

CONTROLLER – Connect the controller to the 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 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.

CH230 OPERATION

TheCHEMTROL® 230 ORP Digital Controller automatically maintains the sanitizer ORP (oxidation-reduction potential or Redox) level. All operating functions are clearly labelled and accessible from the front panel, with many safety and easy-reset features not found on other controllers:

ORP setpoint from 400 to 900 mV
ORP feed mode: off, manual, automatic
ORP proportional control bandwidth from 0 to 100% of the setpoint
ORP high and low alarms from 400 to 900 mV
ORP overfeed safety timer from 0 to 999 minutes

To select a function, simply press ORP and then the desired function. The display shows the current function value. Use the UP or DOWN arrows to adjust to the desired value.

SETPOINT

The standard factory-set ORP control level is 700 mV, based onWORLD HEALTH ORGANIZATION (WHO) values for prevention of germs and bacteria.

To change the control level, press ORP and then SETPOINT. Use the UP or DOWN arrows to adjust the ORP setpoints. To save the new setpoint value and exit, press SETPOINT again.

The controller then automatically activates the chemical feeder for sanitizer feed, as required to maintain the set ORP levels – regardless of fluctuations in bather load, contamination and weather. Like a thermostat maintaining a constant temperature, it prevents overfeeding or underfeeding, both of which are detrimental to good water quality.

ALARMS

When there is an alarm condition, the corresponding display flashes the alarm value:

ORP out-of-range
ORP overfeed

The display stops flashing when the condition is corrected. To reset the overfeed timers, turn the feed mode to off and then back to Manual or Auto.

RESET

The ideal values are set as default values. They can be adjusted by the operator at any time. To reset all factory default values, press ORP for 5 seconds.
