When the power level is set to 10 on the ColorChlor or TechniChlor, the unit will always be on except when in a light show. Power level 10 also doesn’t use temperature compensation.

If you use your SPA every day, and keep the power level set to 10, there is a good chance that the chlorine level is just right. If you don’t use your SPA for a couple days there is also a good chance that at this power level it will make too much chlorine when it isn’t used as the unit will be on all the time. If you set the power level to 6, then when you use your SPA the boost mode will keep it on for 24 hours after the light show which is like power level 10 for one day. Then if you don’t use your SPA for a couple days there will likely not be too much chlorine production. Note that power levels 6 through 9 will all be on for the full 24 hours after a light show which is the boost mode. The boost mode will increase the on time by 3.

The power levels chlorine production on times are:

PL 10: ON 100%, no temperature compensation.

PL 9: ON 83%, boost level 100% for 24 hours

PL 8: ON 68%, boost level 100% for 24 hours

PL 7: ON 51%, boost level 100% for 24 hours

PL 6: ON 34%, boost level 100% for 24 hours

PL 5: ON 25%, boost level 75% for 24 hours

PL 4: ON 16%, boost level 48% for 24 hours

PL 3: ON 8%, boost level 24% for 24 hours

PL 2: ON 4%, boost level 12% for 24 hours

PL 1: ON 0.5%, boost level 1.5% for 24 hours

The software version will be listed on the TechniChlor and ColorChlor next to the serial number label. To see what specific changes have been made to the particular unit you have refer to the ColorChlor pages at www.ControlOMatic.com. These changes may not be documented in the owner’s manual.

Software Version 1

Customer Request: Increased the light show time from 10 minutes to 15 minutes. The time off after the light show until chlorine generation will commence is also 15 minutes.

Customer Request: When used in very small SPA’s that are not used very often the ColorChlor makes too much chlorine even at the lowest power level. Turns out that when the ColorChlor is in an off cycle it checks to see if it has been removed from the water in order to start a light show, this checking was making more chlorine than we expected. The checking interval was 1 second and has been increased to 2.5 seconds. The on time was also decreased from 7.5 minutes to 2 minutes and the 1 minute minimum on time has been removed.
