5.2.4 Integrated pH controller (modelos NEO-XX PH y NEO-XX +)
The integrated pH / ORP controller is supplied with a default factory calibration and programmed with the following parameters:
SETPOINT pH=”7.2” / ORP=”700 mV”
IMPORTANT: In order to have a correct regulation of the pH value, the Total Alkalinity of the pool water must be maintained in the range 60–120
ppm CaCO
3
. Use a pool water test kit to check the Total Alkalinity and adjust manually if necessary.
CONNECTION OF THE PH / ORP SENSORS (models NEO-XX PH and NEO-XX +)
Connect the pH / ORP sensor provided with the unit to the corresponding BNC connectors located in the unit’s base (Fig. 26).
CONNECTION OF THE DOSAGE PUMP
The DOMOTIC Series systems (NEO-XXPH and NEO-XX +) have a connector on their base for connecting a dosage pump to control the pH of the
water in the pool. The dosage pump can be connected through the CEE22 connector supplied for that purpose with the equipment (Fig. 26).
