2.0 QUICK START REFERENCE Use this section for reference - please read all safety instructions and appropriate manual sections for installation and operation instructions. • Do NOT add chemicals to feeders until all start-up operations are completed. • Manually adjust and balance pool/spa to acceptable levels and verify using DPD test kit prior to start-up. Automation should be used to maintain chemical levels, not to balance a pool/spa that is out of acceptable chemical ranges.
3.0 Description and Specifications 3.1 General Description The controller is a microprocessor-based chemical automation system, which continuously monitors and maintains the pH balance and sanitizer level in a swimming pool or spa. The pH and sanitizer level (ORP) are displayed using sun-bright seven-segment light emitting diodes. The pH and ORP levels are continuously monitored and displayed on the controller’s front panel. The ORP/pH controller has been designed to be user friendly.
NOTE: When automating any body of water, it is essential to size the feeders to reach desired levels in a relatively short period of time. Generally, automating an existing body of water with existing feeders will require the output of the feeders be increased accordingly. If feeders are unable to keep up with demand in a short period of time, automation becomes ineffective. 3.2 Specifications Parameter pH: ORP: ORP1: ORP1: Display 6.8 to 8.4 0 to 995 mV (5 mv increments) (5 mv increments) Control 7.
3.3 Description of Controls 1. WATER FLOW LAMP Illuminates bright when water flow is indicated. Also indicates that power is on. 2. pH/ORP ALERT LAMPS Illuminates red when the Hi or Low Alert levels are reached. 3. CHEMICAL FEED LAMPS pH FEED lamp flashes while feeding chemical and illuminates steady during feed delay. ORP1 & ORP2 FEED lamp flashes while feeding chemical and illuminates steady during feed delay. pH ORP FLOW SWITCH pH OUTPUT ORP1 OUTPUT ORP2 OUTPUT POWER 4.
On/off mode: • To turn the controller “on”: press the MODE button. • To turn the controller “OFF” :press & change MODE to pH or ORP and hold the MODE button for two seconds until both displays read “OFF”. Release the MODE button and the controller turns off and the displays go blank. Note: Turning the controller “OFF” using the MODE button simply turns off the controller functions, but does not turn off the power to the controller.
pH Calibrate: This button allows the operator to calibrate the pH sensor to a buffer or to a sample tested with a test kit. Pressing the pH CALB button allows the operator to set the pH reading to the desired pH level. NOTE: The sample to be tested should always be taken from the flow cell or container in which the pH sensor is located. The pH calibration allows the adjustment of +/- 1 pH in .1 pH increments. ORP1 mode: This enables the first five programming buttons to set the desired ORP parameters.
4.0 Installation 4.1 Locating the controller Install the chemical pump and erosion feed systems as shown in manuals included with the feeders. The controller may need to be set for the particular feeder system used. Before installing the controller, it is important to do a site assessment to consider where and how you will mount the unit.

NSF certification of this automated controller requires the use of a flow switch. To install a flow switch, remove the jumper and install the flow switch leads. Note: with the flow switch installed and the jumper removed, the flow light will no longer operate as a power light. It is recommended the jumper be retained to assist in trouble shooting if necessary.
5.3 ORP settings The controller displays direct ORP readings and the sanitizer level controlled by this reading. The ORP display indicates the effectiveness of the sanitizer; it does not directly correlate to a chlorine ppm reading. Use a DPD test kit to measure the free chlorine. Adjust the ORP Set Level to the desired level. If desired, set the OPR level to correspond to the OPR reading when the water is balanced to the desired chlorine ppm.
B. Displayed chemical level does not correspond to actual level * ORP=0, pH=6.8 indicates sensors (probe) are attached to incorrect connector * Sensors (probe) need cleaning. * Sensors (probe) need replacing. Note: OPR probe reading can be affected by pH probe. Both probes must be in good operating condition. C. Set-points not being reached/maintained * Factory setting for feed time is 0.6 sec on with 5 minute delay. Feeders may require longer feed time.
7.0 Warranty and ServiceLimited Warranty: Rola-Chem Corporation warrants the original purchaser that this unit is free from manufacturing defects in material and workmanship from the date of the original purchase for one (1) year. If this unit fails within the one (1) year period, it will be repaired or replaced (RolaChem’s option) at no charge, when returned to Rola-Chem Corporation with proof of purchase receipt.
8.0 Appendix 8.1 Dip switch settings The controller has dip switches to control functions/options that are not accessible on the front panel. These dip switches are located inside the power access panel. See section 3.3. The default for switches #1 and #2 is the ON position. The default for switches #3 and #4 is the OFF position. NSF certification of this automated controller requires the feed mode limit (switch #2) to remain in the ON position.
8.2 Factory Default Setting Reset: The controller can be reset at any time to the default factory settings. The factory presets are: ORP set level: 650mv pH set level: 7.4 ORP alerts: high- 900 mv, low- 100 mv pH alerts: high- 8.0, low- 7.0 Feed time: 0.6 seconds To reset default settings, follow these steps: A. Turn the controller Off: Press ‘MODE’ to ORP or pH and then hold ‘MODE’. The display will read “oFF”. Release the ‘MODE’ button. Only the flow light should be on. B.
