Pentair IntelliChlor Installation
Connect a supported Pentair IntelliChlor interface using its terminal labels and exact model instructions. This guide does not establish compatibility for every model sold under this name.
Before wiring
Have a qualified installer isolate all supplies to Clyr and the equipment, verify absence of voltage, and identify the exact model and communication connector before touching wiring. Turning equipment off in the app is not electrical isolation.
Use the terminal functions below. Manufacturer color labels identify terminal functions; arbitrary cable insulation colors do not change those functions. Keep each network pair together: A1/B1 or A2/B2.
The equipment retains its own manufacturer-specified power supply. Confirm the communication power terminal voltage, supply direction and approved Clyr interface before connecting a red lead. Do not join two power outputs. Clyr+ uses an internal 24 VDC supply; that does not mean the equipment communication port accepts 24 VDC. Stop and contact Clyr support if the power arrangement is not documented for the exact hardware. Pentair labels its communication power terminal +15 V. The previous blanket 10-24 V instruction must not be used.
Communication terminals
| Equipment terminal / standard color | Clyr connection |
|---|---|
| Yellow / terminal 3 / +DT | Clyr A1 for Network 1 or A2 for Network 2 |
| Green / terminal 2 / -DT | Clyr B1 for Network 1 or B2 for Network 2 |
| Black / terminal 1 / GND | Clyr communication GND; not protective earth |
| Red / terminal 4 / +15 V | Model-specific communication power; never connect directly to Clyr+ 24 VDC |
Connect and commission
- Connect the verified data pair and required communication common with all power isolated. Secure the conductors; restore barriers and covers before restoring power.
- In the Clyr app, open Settings > Devices > Add > Pool Equipment > Salt Cell. Select the supported Pentair IntelliChlor entry for the exact model. Choose Network 1 for A1/B1 or Network 2 for A2/B2.
- Set the equipment address or control mode only as required by the exact manufacturer instructions and the supported Clyr configuration. Do not copy an address or DIP-switch position from a different model.
- With the pump running and flow verified, activate the salt cell and command a low output. Verify communication and equipment response; a command acknowledgement alone does not prove flow or chlorine production.
- Return to the intended schedule and verify cell operation stops as intended before pump shutdown. Keep chlorination off when flow is absent or uncertain.
Pump and flow requirements
Do not rely on Clyr to start or check the circulation pump before issuing a chlorination command. Verify actual pump operation and adequate flow before activating the cell or changing its output. Keep every salt-cell schedule and program within pump operation; manual controls can override schedules. Preserve manufacturer-required electrical interlocks and flow protection. A schedule is not a pump interlock. Pentair directs the Power Center AC connection to the load side of the filter-pump relay for maximum safety. Have the installer verify the required arrangement for a variable-speed pump.
Troubleshooting
If communication fails, switch off and isolate power before checking the selected network, equipment mode/address, conductor functions and terminal seating. Do not randomly swap wires or probe an open energized cabinet. Keep the equipment off until the wiring and power arrangement are verified.
