1. DESCRIPTION
The Innowater RX allows you to correct the ORP level of your pool. The device
monitors the ORP continuously by means of its ORP sensor and then, when needed,
sends a signal (dry contact) to activate an oxidant doser/producer device.

2. INSTALLATION
Controller
Install the device on the wall in easy to access location using the braquet provided.
Before attaching the bracket to the equipment, use the bracket to mark in the wall
the location of the holes you will need to make for the screws. Choose a location
close to the injection point.
ORP probe
Install the probe after the filter and BEFORE the chlorinator cell and as far as
posible from it. Try to choose a point in the circuit that never get empty of water,
because the probe deteriorates quickly when dry.
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.
Connect the cable to the external control input of the chlorinator or use it to
activate a relay or other device.
If you use the cable to switch a voltage, do not exceed the following values :
Maximum voltage 230 VAC
Maximum current 1 A

4. ORP CONFIGURATION AND CALIBRATION
ORP control cable output
The control cable provides a voltage-free contact between its two wires. Depending
on the configuration of the setpoints this contact can generate a signal with a
variable work cycle (PWM) proportional to the measurement, or an ON/OFF signal.
To use this cable to control a Chlorinator, configure the output in ON/OFF mode.
Connect the cable to the external control input of the Chlorinator or connect it to
operate with a relay or other device.
If you use the cable to switch a voltage, do not exceed the following values:
Maximum admissible voltage 230 VAC
Maximum admissible current 1 A
If percentage, when calculated, is different of 0% or 100%, contact will open and
close according to a variable work cycle (PWM) in cycles of 100 seconds. For
example, if the calculated dosaje is 40%, contact will remain closed (ON) during first
40 seconds and open (OFF) for the rest 60 seconds.
Current status of this contact is shown permanently on display. When turning on the
device, it will wait for the ORP value to stabilize so, altough dosage is at 100%, ORP
output will remain OFF for a period of time. Also, the device has an hysteresis to
avoid fast changes and rebounds.
4.1 Setpoint
To enter press OK, it will show the following screen:
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 80%
B: RH 700mV 20%

- When the ORP is below the lower set point, the signal will work at its maximum
frequency.
- When the ORP 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 ORP is
at 675 mV the pump will dose at 50%.
- When the ORP is above the upper set point, the equipment will keep the output
OFF, at 0%.
You can set both points and choose the percentage of dosage for each of them. To
make this, press cursor with the MENU key in the parameter you want to modify
and scroll with the arrows to change the value.
Press OK key to save the data and Exit the sub-menu.
By setting the set points you will be defining at the same time the % of production
desired in each of those points, both dependent on the size of your pool. For
example, if your pool has a high volume you should establish high production
percentages. The response time in the measurement of the ORP of your pool can
be considered when establishing the set point B by cutting the signal before
reaching the desired ORP value. For example, to obtain an ORP = 750mV and avoid
overproduction, set the dosage cut to a somewhat lower value:
B: ORP 730mV 0%
We recommend to make periodic recalibrations of the ORP electrode.
A: RH 650mV 80%
B: RH 700mV 20%

4.2 “ON/OFF” mode TO WORK WITH A SALT WATER CHLORINATOR
If you set the same ORP value in both points and dosage in A is 100%, output will
behave as a “ON/OFF” signal:
- When ORP is below the value, output will remain ON (closed contact)
- If ORP is above the value, output will remain OFF (open contact)
4.2.1 To work with a domestic INNOWATER salt water chlorinator, you
have to set the following parameters in the chlorinator:
Enter “Control Ext” in the main menu:
Activate external control:
In “2 Mode”, choose the option “Open = active”:
A: ORP 650 100%
B: ORP 650 0%

In “3 Production”, set 0%:
This way, when chlorinator receives the order to produce chlorine, it will do it at the
percentage chosen from the main screen. If the order is not to produce, it will
remain at 0%.
4.3 Probe calibration
The ORP probes require a calibration before their first use and then they need to be
calibrated periodically. It is because different probes can have different answers and
because the response of the same probe inevitably varies with time.
The calibration consists of measuring the response of the probe introducing it in two
buffer solution and recording this response in order to deduct the ORP (RH) of any
other solution, in our case, the ORP (RH) of the water in the pool.
The calibration of the probe is carried out using a buffer solution supplied (220mV)
and entering the sub-menu "3 ORP Calib.”.
Enter the sub-menu 3 ORP Calib. by pressing OK key, it will show the following
screen:
The value on the left (Lec:): indicates the current ORP (RH) value measured by the
probe. The value on the right, indicates the value of the buffer solution (220mV).
You can adjust this value using the arrows to adapt it to the temperature and the
sample used.
Insert the probe in the buffer solution 220mV, remove it slightly with the probe and
wait for a stable reading value to be reached.
Once the reading value has stabilized press OK key to save the calibration and exit
the sub-menu.
Next, remove the probe from the buffer solution 220mV, rinse its bottom with clean
water and shake gently to remove excess water.

4.4 Factory calibration
The submenu 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.
Press OK key to enter the sub-menu 5 Factory calib, it will show the following
screen:
Press OK key to set Factory values or MENU to Exit.
