This step allows you to give your spa a name and provide its location details. By entering this information, your spa will be easier to identify within the app.

Choose any name that will help you recognize your spa in the app (e.g., Backyard Spa, Mountain Retreat, Family Spa).

The 📍 icon next to Address Line 1 can help autofill your location using your device’s GPS.

This step helps the app understand your spa type and water volume. Providing these details ensures more accurate water care guidance, chemical balance recommendations, and monitoring. You can adjust this information later in Settings > General if you discover your values were off.

Choose the category that best matches your spa:

• Spa → Typically holds up to 600 gallons (U.S.).
• Swim Spa → Typically holds more than 600 gallons (U.S.) and is larger, designed for both relaxation and exercise.

Enter the total water capacity of your spa in the selected units. For best results, use the official capacity listed in your spa’s user manual.

This step sets how your spa water will be sanitized. The app uses this choice to provide tailored guidance for chemical balancing, reminders, and shock treatments.

This step ensures your in.touch EN (Home) communication module is properly connected to your home network.

This is the module that connects to your home router. You can identify it by the Ethernet port and the QR code on its label. Download the Quick Start Guide to install this device.

This module connects directly to your spa system. Download the Quick Start Guide to install this device.

Make sure your mobile device is connected to the same Wi‑Fi network as the router linked to the in.touch EN (Home). Otherwise, the app will not be able to detect it.

A solid green light on the in.touch EN (Home) module means it is connected to your router and ready to be set up in the app. This is typically shown during the first connection. If the light is a different color, refer to the guide below for an explanation.

A solid yellow light on the in.touch EN (Home) module means the system is initializing. This state normally lasts only a few seconds. If the LED remains yellow for an extended time, disconnect the power cord and reconnect it.

A solid red light on the in.touch EN (Home) module means it is not detecting a router. Make sure the router is powered and working correctly, the Ethernet cable is properly connected at both ends, and try another cable if needed. If a computer works on that LAN port and the cable is fine, the Home Transmitter may be defective.

A rapidly blinking red light on the in.touch EN (Home) module means the module is installing a firmware update. During this process, the device is updating its system files and must not be powered off. Updates usually take only a few minutes. If the light continues blinking for longer, restart the device to retry the update. If the issue persists, contact support.

A solid blue light on the in.touch EN (Home) module means it has a full Internet connection, with access to the cloud. A blue light also means your module is already associated with an account. If your device and application have Internet access, you’re good to go!

A solid purple light on the in.touch EN (Home) module means it is connected to your Wi-Fi but can’t reach the internet. Your module has been added to your account, but the connection to the cloud isn’t working. Please check that your internet connection is active and stable. If the problem continues, your router settings may need to be adjusted.

A slow blinking white light on the in.touch EN (Home) means a critical error has occurred and the device cannot be identified. This issue cannot be fixed through the app. Please contact the support for assistance.

A slow blinking light in any color (except white) means the in.touch EN (Home) module is in pairing mode and not yet connected to the spa. The app won’t be able to connect until pairing is successfully completed between the Home (EN) and the Spa (CO) module.

A rapidly blinking blue light on the in.touch EN (Home) module means it is saving a backup of its current software. This protects the system so it can be restored if needed. Do not turn off the device during this process. If the backup takes longer than expected, restart the device.

This step helps the app identify and connect to your in.touch EN (Home) module. The easiest way is scanning the QR code on the module.

• The QR code is on the back of the in.touch EN (Home) module.
• Look for a white label with the model and serial number; the QR code is printed there.
• Ensure good lighting so your device’s camera can read the code.

• Scan the QR Code (recommended)
  • Point your device’s camera at the QR code to automatically capture and register your module.
• Register Manually
  • If your camera can’t read the QR code or the label isn’t accessible, choose Register Manually and the app will discover in.touch EN modules on your Wi‑Fi network.

• The QR code is unique to your module and ensures the app pairs with the correct device.
• If the QR code is damaged or unreadable, use the manual registration option.
• Once registered, the module cannot be paired again with another spa.

“QR code not recognized. Try again or continue without scanning.” This alert appears when:

• The QR code is invalid or does not belong to an in.touch EN (Home) module.
• The scan was unsuccessful (blurred image, poor lighting, or partially covered code).

What to do:

1. Try scanning again with good lighting and a clear view of the code.
2. If scanning still fails, tap Register Manually to enter details instead.

This step appears if you choose Register Manually. The app searches your Wi‑Fi network for in.touch EN (Home) modules connected to the same router as your phone.

• The app lists all detected modules on your network.
• Only in.touch 3 or in.touch 3+ modules are compatible with this app.
• in.touch 2 modules will appear grayed out with the note “Not compatible with this app.”

• Module type (in.touch 2 or in.touch 3)
• Serial Number (S/N)
• Version
• IP Address

• Select a Spa
  • Tap the compatible in.touch 3 module to register it with the app.
• Detect More Spas
  • Scan your network again to refresh the list.

• Make sure your phone is on the same Wi‑Fi network as the in.touch EN (Home) module.
• If you only see in.touch 2 modules, your hardware is not supported by this app.
• If your spa doesn’t appear, tap Detect More Spas, or check module power and network connection.

This step ensures that the app connects securely to your in.touch EN (Home) module. Enter the pairing key printed on the module label.

• You’ll find it on the back of the in.touch EN module, printed on the white label with the serial number and QR code.

• The pairing key is unique and ensures the app links to the correct spa.
• If the code doesn’t work, double‑check that you entered all digits correctly.
• Make sure you are entering the Pairing Key, not the Serial Number.

1. If the app rejects the code, verify your module is an in.touch 3 or 3+ (in.touch 2 is not compatible).
