Disinfection control
3.5.4.2.1 Dosage controlled by ORP
ORP control is available for controlled disinfection. A sensor is required to perform the control. The water condition sensor type
varies, depending on the chemical method used for treatment.
pH+ORP sensor is required, correctly installed as per 3.5.2.
Configure ORP control in the WATER AND TREATMENT menu, program ORP CONTROL (See 5.4.3 ORP Control for
further details).
3.5.4.2.2 Dosage controlled by volume and temperature
This function adjusts disinfectant volume injected based on:
o Dosing pump flow rate
o Pool volume
o Water temperature
Targeted dosage is 2ml/m3/day
Dosage will progressively be increased to twice the initial amount when water temperature goes from 22°C to 28°C.
An extra setting will allow to reduce by 50% or increase by 50% to take pool environment into account.
Configure Remnant control in the WATER AND TREATMENT menu, program REMNANT INJECTION (See 5.4.4 Remnant
Injection for further details).
3.5.4.2.3 Dosage Controlled by timers
Calculate an appropriate dosing time.
Refer to the instruction manual and pump rate, and the instructions for use of the chemical to be injected.
Generally, the larger the pool the higher this set time will be. The volume dosing is calculated as follows:
Dosing Time x Pump Size = Total Dosing Volume
Example: Dose time 3 min, Pump Size 25 ml/min therefore 3 min x 25 ml = 75 ml in 3 minutes.
In the AUXILIARIES menu, set the timer for the appropriate auxiliary to run for the calculated dosing time during a
programmed filtration cycle.
In the AUXILIARIES menu, set SLAVE: YES.
In the AUXILIARIES menu, select days of the week on which dosing is to take place.
