Steps

Step by Step

Top

Step 1

ON/OFF – This button turns power to the Control Unit on and off. In an OFF state, all LEDs are off and the display will show the current time and POWER OFF. To turn the Control Unit ON, press the button once. The POWER ON LED and one of the POLARITY 1 or 2 LEDs will illuminate and the display will show time and the % of current Chlorine Output setting. Note that this button only turns on power to the Control Unit. The SET TIMER and OUTPUT functions (described next) may have to be set to pass power to the Cell and generate chlorine.

Step 2

SET TIMER – The Control Unit has the option of working off an external timer or off of two internal timers. This function allows you to set two internal timers to generate two chlorination cycles per day. To enter the timer mode, press the SELECT button and hold it for 3 seconds. The Display screen will ask WHAT LANGUAGE? Select a language with the up and down arrows. Then press SELECT again. The Display will now show WHICH TIMER? EXTERNAL. If you want to bypass the internal timers, press SELECT to go to the next setting (SET CLOCK). If you want to set the internal timers, press the down arrow to change the setting to INTERNAL. Pressing the SELECT button again will display ON TIME 1. Select the start time hours for Timer 1 with the up/down arrows. To change AM to PM, you have to keep scrolling through the hours until you get to the AM or PM setting you need. To set the minutes, use the right OUTPUT arrow to move the cursor from under the hours to under the minutes and then change minutes with the up/down arrows. Press the SELECT button to display OFF TIME 1 – set the end time for Timer 1. Set TIME 2 using the same process as above. Then press SELECT once more to SET CLOCK. A final push on SELECT will exit and return your Display to normal operation mode.

Step 3

SET CHLORINE OUTPUT LEVEL –The Chlorine production level can be set from 0% to 100 % in increments of 10%. To set the production level, press the OUTPUT arrows left or right. The % Output level will be shown in the Display. Note, at a Output level of 0% the Cell is turned off and the display will read OUTPUT OFF.

Step 4

SUPERCHLOR - There are occasions when you will need higher than normal amounts of chlorine to be generated - when you have an abnormally high swimmer load, after a heavy rain, or if you have a cloudy water condition. To increase the level of chlorination, simply press the SUPERCHLOR button. This electronically "super chlorinates" the water by increasing output to 100% for a cumulative 24 hours. If, for example, your pump runs 8 hours a day, the Cell will remain in SUPERCHLOR mode for three days before returning to normal operation. Or, if you elect to stop SUPERCHLOR at any time, you can simply push the SUPERCHLOR button again to return to normal operation.

Step 5

WINTER MODE - If you are not using your pool during the winter months, we recommend that you put the chlorinator in WINTER MODE by pressing the WINTER MODE botton. This reduces the output of chlorine by 50% of your current output setting. For example, if your output is set at 80%, pressing the WINTER MODE button will reduce the output to 40%. To return to normal operation in the spring, push the WINTER MODE button again.

Step 6

MANUAL OVERRIDE - If the Control Unit is operating between the two internal timers (between OFF TIME 1 and ON TIME 2), it's in IDLE mode and the Cell in OFF. To manually override this function, press the SUPERCHLOR button. The cell will come on in SUPERCHLOR mode.

Step 7

POWER LED - When this LED is illuminated, the Compupool Control Unit has input power. This only indicates that the Control Unit has power. The timer has to be on and the output level must be greater that 0% for the cell to be active and generating chlorine.

Step 8

POLARITY 1 or 2 LEDs - When either is illuminated, it shows which end of the cell is producing chlorine.

Step 9

WATER FAULT LED - When illuminated, the flow switch has detected that no water is flowing and the cell has stopped generating chlorine. The Display will read NO WATER. Check pump operation.

Step 10

ADD SALT LED - When illuminated, the salt level is too low and the cell is generating at low efficiency. Additional salt should be added. See our guide on "How To Add Salt To Your Pool".

Step 11

OVER SALT LED - When illuminated, indicates that the salt level is too high. To get the salt level back to acceptable levels and turn off this LED, purge some water out the WASTE line of your filter and add fresh water to the pool. See our guide on "How To Reduce the Salt Level In Your Pool". If you do not bring the salt level to within the acceptable, the cell will draw more current, run hotter, and fail.sooner than normal.

Hello. Just woundering is all the main computer of the compu pool the same. I have a salt cell that is CPSC16. Am I able to put a bigger salt cell in the casing and run the same brain (computer) in it. Example. CPSC36 CPSC48

The CompuPool CPSC used the same power pack for all the model's cell sizes.

I have solution for "COMPUPOOL COVER CLOSED PROBLEM" Clear the setting for a cover sensor in the Maintenance menu: The main power must be turned off at the supply. 2. Press and hold the SUPERCHLOR and WINTERMODE button simultaneously, (see Fig. 2 O) and turn the mains power back on. 3. Hold both buttons for approximately 10 seconds and release. All LED’s will light up until the buttons are released. The maintenance menu is now activated Cycle through the settings by clicking the select key (one way); change values up and down via up and down keys. Select to accept new setting and move to next. There is no temp measurement, next, save setting at end.

There is a maintenance mode/menu accessible by pressing winter & superchlor buttons together. As my display is dying and difficult to read can anyone advise what sequence this extra menu is?

Anonymous (CPSC36) - Unfortunately, Compupool has pulled out of the US and we no long have access to their technical support for questions like these. It sounds like your units amperage is running too high. If the melted parts are not severe, make sure the leads to the terminals are tight - crimp them slightly.

I replaced CPSC36 element and housing because the electrical wall where the 3 posts are located was leaking. Now, the plastic around the BLACK post is melted and the BLACK wire is also melted. Any thoughts?????

gav - It is my understanding that the time between changing from one polarity to the other cannot be changed by the user.
 Reply

 Posted: 4/8/2017 

Is there a way to alter the time between the cells changing from Polarity 1 and Polarity 2? I understand that it is probably factory set, but I'd like to know if I can change this time.

I have an infinity salt system my polarity 2 light keeps coming on what does this mean.also my poolis alway low on chlorine but my salt level is 3400
 Reply

InyoPools Product Specialist  Posted: 9/19/2016 

tiffmiester - No, only one polarity light should be on at a time even in superchlor mode. Try crimping the female connections on the cell plug to create a tighter fit around the plug terminals.
 Reply

 Posted: 9/16/2016 

are both polarity lights supposed to be on when in super chlor mode????

Sharon - Usually the water flow LED indicates a pump issue producing low water flow. A common pump problem is a clogged impeller. See our guide on "How To Clean Out a Pool Pump Impeller". other water flow issues are covered in "How To Determine the Cause of Low Water Flow".

I see quite a few comments
About the water fault issue. I have the same problem - indicates water fault/cell temp. I've cleaned the salt cell, added salt, chlorine, stabilizer. Still same issue. Any suggestions? Even my pool company who installed this can't figure it out.

How do i know my control unit isnt messed up
 Reply

InyoPools Product Specialist  Posted: 5/11/2016 

Donna - I haven't seen that particular display, but the "no water" part would indicate that the cell is not receiving sufficient water. Make sure that the water is coming in the cell port labeled "input". Check that the terminals on the cell side of the control cable are tight. Then call Compupool at 888-989-7258 for further analysis.

What is the order of the three blue, black and red wires from top (serial #) to bottom for reconnecting?

john - According to para 9.3.3 3 of the user's manual: Manual Override. This button allows you a manual override to control the system without having to change the unit's settings. When you have finished with the manual override simply re-press the button to de-activate and return your unit to its normal settings.

Mad - Sometimes the wires connected to the cell posts become loose and give intermittent control signals. Try tightening up the connections by cleaning the posts and slightly crimping the female connectors that attach to the cell posts. If this doesn't work, give Compupool a call at 888-989-7258. Their tech staff should be able to help your further.

Sherri - Try slightly crimping the female connections on the cable that attaches to the cell plug. Sometime a loose connection will give you those kinds of readings. If that doesn't work, give Compupool a call at 888-959-7258 and ask for their tech staff. They should be able to give you a solution.

My water fault light is on and the screen reads no water. I cleaned the cell, Pump basket and filter. I also wire brushed the red, blue and black plugs. All valves are open as they should be. The cell is 4 yrs old but gets used about 3.5 mos a year. If you have suggestions, please explain in detail because I am new at this and still learning.

Had this system a few years now. We cant seem to regulate/keep the correct Ph and Alkalinity. Pool turns green very often. Especially after it rains. After water testing, we are again adding more salt. Spending a fortune on products. Help

Darlene - Try tightening up the cable connections by slightly crimping the female leads that attach to the posts on the cell plug. If that doesn't correct your problem, you may need a new PCB. Before you buy a PCB, give Compupool a call at 888-989-7258 and have them confirm this.

Jean - Check and make sure your terminal connections are tight where the three cable wires attach to the cell plug. SLIGHTLY crimp the female ends of the cable wires that attach to the posts in the cell plug. If this doesn't work, Give Compupool a call at 888-959-7258 and ask for tech support.

My Compupool Salt Chlorine Generator says low salt and when tested it seems to be between 3200 and 3600 depending which company is testing. So it really isn't low on salt. Why does the light stay on? How can I solve this problem? Cleaned the cell and it is producing chlorine.

InyoPools Product Specialist  Posted: 6/14/2015 

Rebeck4 - Make sure all your pool chemicals are within range. Then try tightening up the terminal connections at the head of the cell by slightly crimping the female leads on the cable. If that doesn't work, give Compupool a call at 888-989-7258 to see what "temp sensor shorted" means.
 Reply

 Posted: 6/12/2015 

My CPX24 is not making chlorine. I have tried re-setting back to factory settings, cleaned the element as prescribed in manual, and cleaned skimmer baskets. The only thing I see wrong is a message that says: temp sensor shorted. What should I do? The unit is under warranty.

InyoPools Product Specialist  Posted: 10/17/2014 

Joefl - Check the cable connections at the cell head. They sometimes become corroded or loose. Also See our guide on "How To Isolate and Correct Compupool CPSC Problems" for more information.

I have comp24 that worked fine for 9 months then the housing that holds the cell started to leak.While it was leaking it wasn't making chlorine.Compupool send me A replacement housing and that stopped the leaking. .But it isn't making chlorine.Any Ideas.??

InyoPools Product Specialist  Posted: 9/8/2014 

tiffeiffic - If by "cells" you mean the "polarity 1" and the "polarity 2" LED lights, the answer is no. Only one of these lights should be on even during "superchlor".
