Chiller control
Configure a compatible external cooling input and verify temperature-based operation.
01 / Start with the right guide
Match your equipment
Use this guide for a chiller with an approved external control interface wired through the correct Clyr output. A reversible RS-485 heat pump uses the Madimack heat-pump guide instead.

How the parts work together. This is a system overview, not a terminal wiring diagram.
02 / Get ready
Before you start
- Record the equipment model, controller generation and installed software version. Use the matching product manuals.
- Have a qualified installer isolate every relevant electrical supply and verify absence of voltage before opening equipment. Turning it off in the app does not isolate power.
- Confirm the circulation pump runs and water is flowing before requesting heat, cooling or chlorination. Keep the manufacturer’s interlocks and flow protection in place.
- Confirm a valid water-temperature source before enabling cooling.
03 / One step at a time
Set it up
Match the external input
Have the installer identify the chiller’s external enable input, required interface and approved Clyr output. Record the output assignment and keep equipment protection intact.
Choose Chiller in the app
Open Settings → Devices → Add, then select the Clyr controller physically connected to this equipment. Open Pool Equipment and choose the item named below. App wording can vary by version.
Choose Chiller, name it, and select the output used by the installer. Set a cooling target appropriate for the pool and equipment.
Verify the temperature reading first
Compare the displayed water temperature with a reliable independent reading. Do not enable automatic cooling with missing or implausible temperature data.
Test cooling and OFF
With circulation established and a valid temperature reading, request cooling when the water is above the commissioned target. Observe the unit’s own response and any required delay. Cancel the request and confirm the expected stop.
Make the schedule match the installation
After the manual checks pass, create the required event in Clyr. Review its start, finish and equipment settings. Keep heating and chlorination within verified pump operation; an overlapping schedule is not a safety interlock.
Shared app skill · not equipment wiring Follow the Clyr scheduling workflow. Select the equipment in this guide and use the times and settings commissioned for your pool.

04 / Prove the result
Check it works
A saved setting tells you what you requested. These checks tell you what the equipment actually did.
- Temperature data is present and plausible.
- The intended chiller responds to cooling demand.
- An OFF request and any required run-on/cooldown are verified.
- The operating schedule stays within the commissioned circulation arrangement.
05 / Find the next useful check
If something is wrong
The device is saved, but it does not respond
Check the selected controller, equipment type, physical network and address against the installer’s record. Check the equipment’s own display for a fault. Isolate power before inspecting connections.
Manual control works, but the schedule does not
Check the event’s day, time, selected device and requested value. Check whether Manual or Service mode is overriding scheduled operation. Return to the intended mode and observe the next event.
06 / Save for later
