Meaning of Configuration Parameters
PARAMETER 01
FUNCTIONING TYPE OF THE PUMP 1
This parameter allows to set the functioning type of pump 1, typically used for the pH control.
PARAMETER 02
SET-POINT PUMP 1
This parameter allows to enter the desired pH value for the swimming pool water. The dosing pump is
activated / de-activated to reach this value and keep it constant.
PARAMETER 03
HYSTERESIS PUMP 1
This parameter is sued to adjust the functioning hysteresis of pump 1 around the threshold set in P02.
It is recommended to set a narrow window in case of ON-OFF mode, while for proportional mode it is
advisable to set a window of at least points.
PARAMETER 04
DOSAGE DIRECTION OF PUMP 1
This parameter allows to set the dosage direction. The choice depends on the product dosed to adjust
the pH level: if you dose an acid, set this parameter to “Acidification”, while if you dose a base set
“Alkalization”.
PARAMETER 05
TIME BASE FOR PUMP 1
If the pump is configured to ON-OFF mode, this parameter indicates a percentage of operation of the
pump, on a fixed time base of 100 seconds. 100% corresponds to pump always ON, while 5% indicates
that the pump is ON for 5% of time (=5 seconds) and OFF for the remaining 96% (=95 seconds).
If the pump is configured for proportional operation, this parameter indicates the time base of pump.
PARAMETER 06
FUNCTIONING TYPE OF THE PUMP 2
This parameter allows to set the functioning type of pump 2, typically used for controlling the redox
potential level. See description of parameter P01.
PARAMETER 07
SET-POINT PUMP 2
See parameter P02, but referred to redox measurements.
PARAMETER 08
HYSTERESIS PUMP 2
See parameter P03, but referred to redox measurements.
PARAMETER 09
DOSAGE DIRECTION OF PUMP 2
See parameter P04, but referred to redox measurements and dosing directions “Chlorination / De-
chlorination”.
PARAMETER 10
TIME BASE FOR PUMP 2
See parameter P05, but referred to the pump 2.
PARAMETER 11
DOSAGE ALARM OF PUMP 1
This parameter allows to generate an alarm when the measurement does not return to the setpoint
value within a set time interval, from 0 (function disabled) to 240 minutes. The counter starts when the
unit detects a measurement that exceeds the setpoint value, and automatically resets to zero when
measurement returns to an acceptable. If measurement remains outside of the setpoint for a time longer
than that set, an alarm is generated, the display shows the message “
Al.1
” and the pump stops dosing.
To reset the alarm and resume to normal operations, press the ON/OFF button or shutdown and restart
the unit.
This condition can occur when the dosage is insufficient to reach the setpoint (P02).
PARAMETER 12
DOSAGE ALARM OF PUMP 2
See parameter P11, but referred to pump 2.
