4.5/ ACL set point
TRi PRO ACL function (« Active Chlorine Level ») made for automatically
‘maintain’ chlorine level to get a good pool’s water disinfection. TRi PRO
module continuously measures the ORP level to control TRi salt water
chlorinator operation.
IMPORTANT REMARKS:
> the ACL set point displayed on the LCD screen does not correspond to
free chlorine level into pool’s water ! It is only the selected level of ‘water’s
disinfection potential’ (ACL).
> The ACL set point required in order to obtain the optimal free chlorine
level is different for each pool. A regular manual chlorine level analysis will
be necessary to correctly adjust the ACL set point.
TRi PRO module has 6 different ACL set points (corresponding to 6 different
ORP levels).
The higher the ACL set point is, the higher the requested “disinfectant action”
will be, as a result the free chlorine level will be potentially higher, and vice
versa.
 To increase potential chlorine generation: increase ACL set point
 To decrease potential chlorine generation: decrease ACL set point
TRi PRO module default ACL set point is #1. (*)
(*) : Default ACL set point could be different depending on your unit software version.
IMPORTANT NOTE: It is recommended to set the ACL set point to #3
or #4 during the fi rst few days after having installed the TRi PRO module
in order to quickly stabilise the free chlorine level (see chapter 7 / ‘Water
balance’). If the free chlorine level is correct after this start-up period, it will
be necessary to adjust the ACL set point accordingly.
To change the ACL set point:
1. Ensure that the ACL sensor has been calibrated (see above procedure).
2. From the default display on the LCD screen, press the button.
3. Use the buttons to display pH/ACL SETUP, then press .
4. Use the
buttons to display ACL SETPOINT, then press .
5. Use the
buttons in order to change the set point value and press
to validate.
6. Press
button 2 times or wait 30 seconds for the TRi power pack to
return to the default display on the LCD screen.
IMPORTANT REMARK: It is not possible to manually adjust the chlorine
output when the TRi PRO module is fi tted on a TRi power pack (
buttons are inoperative). Only the and modes are active (see
TRi salt water chlorinator user manual).

Activating and deactivating the peristaltic pump
For safety reasons, the peristaltic pump of the Zodiac TRi PRO module is
not activated when delivered. When the TRi PRO module is connected to
the TRi power pack, the peristaltic pump is programmed to start operating
automatically approximately 8 hours after turning it on. During this period,
the default display on the LCD screen will display pH ---.
To immediately activate the peristaltic pump:
1. From the default display on the LCD screen, press the button.
2. Use the buttons to display pH/ACL SETUP, then press .
3. Use the
buttons to display ACID PAUSED.
4. Press the button to activate the peristaltic pump ( ACID ENABLED will be
displayed).
5. When appropriate option has been selected, press button 2 times or
wait 30 seconds for the TRi power pack to return to the default display on
the LCD screen.
NOTE: Use the opposite procedure in order to deactivate the peristaltic pump
(default display on the LCD screen will return to pH ---).
Using Zodiac TRI with TRi PRO module
The Zodiac TRi is now ready to automatically regulate the pH and the ACL
levels in the pool water using the TRi PRO module.
1. Set the ‘ON’ and ‘OFF’ times (refer to the Zodiac TRi Salt chlorinator user
manual).
2. If the pool water pH exceeds the set point, the symbol ^ will be displayed to
the right of the pH set point value on the LCD screen. pH minus will then be
released automatically according to the predefi ned cycles.
If the pool water ACL is unsuitable to keep a good disinfectant effect (ORP
too low), the symbol ^ will be displayed to the right of the ACL set point
value on the LCD screen. Chlorine generation will automatically start
according to the predefi ned cycles.
3. Refer to the instructions concerning water balance hereunder in order to
ensure optimal operating conditions for the Zodiac TRi.
 Zodiac TRi Salt chlorinator together with the TRi PRO module will now
automatically maintain the appropriate pH and ACL levels for the pool water.
NOTE: The TRi PRO module is designed to use only pH minus (therefore to
lower the pH). Do NOT use other types of chemicals.
