Page 5: Description
1. DESCRIPTION The pHrx allows you to correct the pH an ORP level of your pool. The device monitors the pH continuously by means of its pH sensor and sends a dosing signal to the pump which will, in turn, injects acid in the pool when needed. The device will control the work of the pump depending on the measurement of the probe and the setpoints programmed.
Page 6: Instalation
Immerse the suction filter together with the level probe that you have fixed to into the acid container and make sure that it stands upright and stable on the bottom. Close the container as good as you can. INNOWATER PHRH...
Page 7 ORP control cable output Control cable provides a dry contact to control the device. Depending on the setpoint configured it can generate a proportional PWM duty cycle or an ON/OFF signal. If the device controls a saltwater chlorinator, setpoint must be configured as an ON/OFF signal.

Page 10: Setpoints
- When the pH is between both points, the chlorinator will send a proportional signal defined by both points. For example, in the case of the figure, if the pH is at 8 the pump will dose at 40%. INNOWATER PHRH...
Page 11: Ph Configuration
- When the pH is above the upper set point, the pump will dose to the fixed volume defined for the upper point. In the case of the figure, 90%. A: pH B: pH You can set both points and choose the percentage of dosage for each of them. To do this, press the cursor with the MENU key in the parameter you want to modify and act with the arrows to change the value.

Factory values. For example, if when calibrating with the pH4 solution the reading value, Lec, indicates 6.05, the calibration won´t be saved and the value 4.00 will be maintained. INNOWATER PHRH...

4.5 Factory calibration pH configuration 5 Factory calib. The submenu 5 Factory calib, gives you the possibility to reset general calibration parameters that correspond, approximately, with those of a new probe and which are the ones programmed by the chlorinator from factory values. This can be useful if you have saved successive calibrations and do not have the buffer solutions for a correct calibration.

5.1 Setpoint ORP Config. 2 Setpoints To enter press OK, it will show the following screen: A: RH 650mV B: RH 700mV The calculation of the production is made by setting of two setpoints, A and B, and the % of production that is desired for each of those points. A: RH 650mV B: RH 700mV - When the ORP is below the lower set point, the signal will work at its maximum...
Page 16 - When ORP is below the value, output will remain ON (closed contact) - If ORP is above the value, output will remain OFF (open contact) 5.2.1 To work with a domestic INNOWATER salt water chlorinator, you have to set the following parameters in the chlorinator: Enter “Control Ext”...
