“Centurio PRO” basic settings.
Basic settings are: PASSWORDs, Time & Date, Language and International Units.
Standard settings are: Probes calibration and working modes (bleed - inhibitor - biocide).
Advanced settings are: Flow meter, Alarm and Communication (WiFi, Mobile, ERMES) menu.
All these three settings must be set in order to properly operate the CONTROLLER.
PASSWORD for main menu (settings) access.
To grant access into main menu tap on from main screen and enter the PASSWORD using the keypad on the right
side of the screen. Default PASSWORD is 0000 (factory preset).
To set a new PASSWORD choose “PASSWORD ” from “Settings” menu and enter a four numbers code. Conrm
changes to activate the new PASSWORD.
Lost PASSWORD ?
Please dont’ forget the PASSWORD (if changed). In the unfortunate event, please call your local distributor for unlocking procedure.
There is no way for you to recover a lost PASSWORD.

International.
Before to program the controller please setup Language, Location and local Time & Date (Settings / International).Since
the controller activities are based on time is essential to setup time and date prior to anything. Within International menu
please choose language and location for proper units format.
Based on location units change according to local rules. To end procedure tap on tick icon for each change.

“Centurio PRO” standard settings.
Standard settings are: Probes calibration and operating modes (bleed - inhibitor - biocide). To calibrate each channel
select it within main menu. Channels availability is based on modules conguration. The controller will automatically add
the proper channel when a new module is installed and detected.
Conductivity calibration menu.
This menu includes probe choice, conductivity calibration , temperature compensation and manual or automatic temperature
compensation. Conductivity calibration procedure involves a zero calibration (First Point) and a 2nd calibration point (Second
Point) that requires a buffer solution with value near working range. Furthermore Temperature and Automatic Compensation
must be set. Note: This procedure assumes that CONTROLLER is correctly installed and congured, connected
to a working probe. Calibrate using plant’s temperature otherwise unattended results might occur. If something
wrong occurs use RECOVERY CALIBRATION to restore to previous calibration.
First Point & Second Point.
During this procedure probe must be dry and clean and not installed in plant. Tap on “First Point” (zero) and conrm it.
Tap on “Second point”, dip probe’s head into buffer solution and wait until reading value is stable, enter buffer solution
value and conrm it.
Temperature Compensation (if available)
Conductivity measurements are temperature dependent. The degree to which temperature affects conductivity varies
from solution to solution and can be calculated using the following formula: C25 = C / {1+[a/100(t-25)]} where: C25 =
slution conductivity at 25°C, C = conductivity at operating temperature, a = temperature coefcient of solution %/°C.

3924 2.1 40°C / 104°F 2984
Samples alphas (a) are listed in the table above. To determine that “a” of other solutions, simply measure conductivity at
a range of temperatures and graphic the change in conductivity versus the change in temperature. “Centurio PRO” has
either xed or adjustable automatic temperature compensation referenced to a standard temperature of 25°C.
Otherwise choose automatic temperature compensation and set % Alpha value.

Chlorine calibration menu.
Chlorine calibration procedure is based on installed chlorine probe and may involve one or two calibration points depen-
ding on probes’ model (see table at next page). From main menu choose “Chlorine” then tap on Calibration”. Installed
probe will be automatically detected and according to model a one or two points calibration will be enabled.
Note: This procedure assumes that CONTROLLER is correctly installed and congured, connected to a working
probe. Calibrate using plant’s temperature otherwise unattended results might occur. If something wrong occurs
use RECOVERY CALIBRATION to restore to previous calibration.
Two points calibration method.
During this procedure probe must be dry and clean and not installed in plant. Use chlorine free water (or a carbon lter
system) and dip probe’s head into it, wait until reading is stable, then ap on “First Point” (zero) to conrm it.
For Second point calibration use a plant’s sample water and analyze it using a DPD system to obtain value. Enter this
value as second point calibration and conrm it.
One point calibration method (second point).
For Second point calibration use a plant’s sample water and analyze it using a DPD system (photometer) to obtain
value. Enter this value as second point calibration and conrm it.
