How to replace an ICO sensor ?

The probes on your ICO are removable and replaceable, so you can change them very easily without having to replace the device itself. They are available individually in Ondilo shop.

The replacement of the probe calibration (bleue), conductivity (grey) or Chlorine/bromine ORP or ORP salt depends on the conditions of use.

The procedure for replacing a probe is identical for an ICO Pool and an ICO Spa.

Never place ICO in water without its sensors and covers.

Steps to change an ICO sensor

Follow the following steps carefully:

Remove the current sensor

Remove ICO from the water and dry it with a soft cloth.

Using the tool provided in the ICO package, remove the probe to be replaced by turning it towards the open padlock pictogram.

Set aside the sensor to be replaced.

Insert the new probe into ICO

Then insert the new probe and turn it clockwise to lock it in place (the arrows should line up).
Check that the pictogram on the probe is aligned with that on the ICO box (the 2 arrows in the middle position).

Launch your ICO again

Once you have replaced the sensor, place the ICO in your swimming pool or spa.

Reset calibration

Register the new sensor in the app

To complete this operation, It is essential to confirm the sensor change if you have already calibrated your sensors. This resets the calibration settings.

In the app, click the button Remote control (bottom right), then click one of the following buttons:

Calibration pH sensor> if you have replaced your pH sensor
Calibration ORP sensor> if you have replaced your ORP sensor

click on the red button Reset (new sensor) at the very bottom. This button only appears once a calibration has been saved.

When replacing an ICO probe, it is essential to reset it in the ICO application before calibration.

If the Reset (new sensor) button does not appear on your screen, this means that no calibration has been done before. Your new sensor can therefore be used. You can therefore skip this step and leave ICO in the water to take measurements.
