🪛Clyr inline ph/ORP/Temp probe install

This tutorial shows you how to connect a pH/ORP/Temp sensor to a Clyr Controller.

RISK OF ELECTROCUTION AND SHOCK - before proceeding with this tutorial please seek advice or help from a certified electrician if you feel uncomfortable with any of the following steps as this tutorial involves working with potentially high voltages and current.

Tools Needed

Before we start hooking up your probe, you'll need the following tools:

  • A Clyr Lite or Clyr Controller

  • PVC cement and primer

  • anywhere from 1 1/4 in. - 2 in. PVC tubing, Tee, 3/4 in. threaded slip for top of tee

  • Clyr pH/ORP/Temp 3-1 inline probe

  • (Optional) Digital flow meeter

  • Ethernet or 4-wire copper cable

  • A small flathead screwdriver

  • A large Phillips screwdriver

Step 1 - Connect your controller

Before you begin, please make sure you have powered on and connected your Clyr Controller.

Step 2 - Assemble bypass

A bypass from the main PVC line will slow the flow of water so that the sensor can make more accurate readings when plumbed inline. Please follow this youtube video to assemble the bypass: https://www.youtube.com/watch?v=_tHdN_mhqxQ

Step 3 - Turn off breaker to main pump

You don't want your pump to turn on accidentally or to have your pool pressurized when installing the bypass, so please turn off the breaker now.

Step 4 - Determine bypass install location

The ideal place to install the bypass is in between your filter and heater or after the heater BUT before chlorination. In addition, the probe will be more accurate the further it is downstream from the pump.


You should need about 10 inches of straight pipe in order to plumb the bypass in place. If you need to plumb the bypass in between the pump and the filters, this is ok.

If you are uncomfortable plumbing PVC, most pool service companies will do this for you on the order of $100-$200 dollars which can save time and make sure this part is done correctly.

A few things you want to double check to make sure the bypass is installed correctly:

  • The probe must be facing towards the ground with the cable on top. If not, the probe will not read correctly

  • The downstream valve on the bypass can be closed slightly, to limit the flow to the probe if needed

  • Teflon tape should be used on the probe itself in the 3/4 in. thread

Step 5 - Wiring Clyr Controller

Now its time to make sure the colors match. If you haven't wired any existing equipment to the Clyr controller, it's a good idea to take our first available network using ports A1 and B1.

What are networks?

Wiring for the probe is straightforward and should be:

  • Probe Red -> Clyr Controller 12V

  • Probe Green -> Clyr Controller A1 (or A2 if on network 2)

  • Probe Yellow -> Clyr Controller B1 (or B2 if on network 2)

  • Probe Black -> Clyr Controller GND

Step 6 - Turn breaker back on

At this point, if the wires are tight and the colors match we're almost ready to add the probe in our app and test it out. Go ahead and turn the breaker back on and then we'll head to the app.

Step 7 - Add the probe in app

You should have already added a Clyr Controller to your pool location in the app at this point. If you haven't check this out first:

Adding the probe has two parts with the same instructions: adding pH and ORP sensors.

Although the Clyr sensor has both pH and ORP in the same sensor, we still must add it as two separate components in the app.

If this has been done you can proceed. Go to your pool location and click "Settings"-> "Devices"-> "Add" -> "Pool Equipment". Once you're on the pool equipment page, we'll select a pH sensor first.

Once you select ph Sensor, we'll need to configure the sensor.

First, choose a name for the sensor. Leave the default as pH.

Next, select either network "1" or "2" depending on if you wired the probe to A1/B1 or A2/B2 respectively.

Click Save and that's it. You should see the pH sensor added in the app.

Repeat this for the ORP sensor.

Once you have finished adding the ORP sensor and see it on the devices page, you're all set.

Step 8 - View sensor data

Once both ORP and pH sensors have been added in the app, you should be able to go to the "Water Quality" tab in the app, hit the button "Refresh Data", and the values should be updated in a few short moments.

Next Steps

Now that your pump is online, you can do all sorts of great stuff like schedules, programs, autopilot and more. Check out those tutorials.


  1. I wired everything up but the sensors still don't show any data?

First, make sure all the probe wires are screwed in tight to the Clyr Controller.

Next, make sure that there is at least 9V of power to the Red and Black connectors on the probe. The probe needs at least 9 Volts of power to transmit readings to the Clyr Controller

Finally, make sure that you added the pH and ORP sensors in the app on the correct RS485 network.
