Hi! I understand you’re having trouble adjusting your heating temperatures using the Cozytouch app on your iPhone 15. Let’s work together to get that sorted out.

To start, can you tell me a bit more about what exactly happens when you try to change the temperatures? For example:
- Does the app let you open the interface to change settings at all?
- When you try to adjust the temperature, does it give any error messages or just not respond?
- Have you noticed if the app crashes, freezes, or behaves unusually on your iPhone 15?
- Also, are you connected to the Cozytouch gateway properly (the device that links your heating system to the app)?

Once I have a clearer picture, I can guide you through some focused steps.

Meanwhile, here are some general things to check on your iPhone 15 with iOS version 26_5_0:
1. App Version: Make sure the Cozytouch app is updated to the latest version through the App Store.
2. Reboot the iPhone: Sometimes restarting the phone can resolve temporary glitches.
3. Check Network Connection: Ensure your iPhone is connected to a stable Wi-Fi or cellular network.
4. Re-login or Re-pair: Try logging out of the app and logging back in, or reconnecting to the Cozytouch gateway if possible.
5. Permission Settings: Go to your iPhone Settings > Cozytouch app and check that all necessary permissions (like network access) are granted.

If you have already tried some or all these steps, please let me know so we can go deeper into troubleshooting. Also, do you know if other users with iPhone 15s are facing this issue, or is it isolated to your setup?

Looking forward to your details so I can assist you better!

I have tried all of the above steps . I can connect with the app but it will not allow me to change the temperature in various rooms

Thanks for letting me know you’ve tried those initial steps and still cannot change the temperature in various rooms, even though the app connects successfully. That really helps narrow it down.

Since the connection to the Cozytouch system is successful but changes aren’t applied, a few deeper scenarios might be causing this:

1. Permissions or User Roles: Sometimes, the Cozytouch system restricts control based on user roles or device permissions set on the gateway or the heating system. Could there be any access limitations configured that prevent remote temperature changes?

2. Gateway or Device Sync Issues: The Cozytouch gateway (bridge connecting your heating system to the app) might be out of sync or experiencing internal errors that prevent writing new settings, even though reading status is fine.

3. Firmware or Software Updates Pending: Check if the Cozytouch gateway or the heating units need firmware updates. Oftentimes, outdated firmware can cause control commands to be rejected.

4. Specific Room or Device Settings: Some rooms or heating units might be set to “manual” mode physically on the device or locked from remote control for safety reasons.

Here are step-by-step actions to try next:

1. Check for Updates:
- Open the Cozytouch app and look for any pending notifications or prompts to update firmware on your gateway or heating units.
- Alternatively, access the gateway directly (if it has a web interface) to verify firmware versions.

2. Verify Access Permissions:
- Within the Cozytouch app, look under account settings or device settings for any access controls or user role restrictions.
- Ensure your app account has full control privileges.

3. Reset Gateway Communication:
- Power cycle (turn off and on) the Cozytouch gateway device. Wait a couple of minutes for it to fully reboot and reconnect.
- Open the app again and try changing temperatures.

4. Check Physical Thermostat Settings:
- Visit the physical thermostat(s) or heating controllers in rooms where you cannot change temperature. Look for a “lock” or “manual mode” setting that might override app commands.
- If manual mode is enabled, switch back to allow remote control.

5. Re-add Devices:
- If possible, remove the affected heating devices from your app account and add them back. This can sometimes clear sync issues.

If these don’t fix the problem, I recommend checking the Cozytouch FAQ and Tutorials for specific troubleshooting related to your heating units and gateway. Also, some users have reported similar issues discussed on forums like Reddit, which could provide insights from real-world experience with various device models and app versions1 3 5.

Would you like detailed help with any of these steps? Or do you know the exact model of your heating devices and the gateway? That info can help me tailor instructions further.

Are you satisfied with the solution I provided so far?

The exact model is ; ARXG18KLLAP

Does Cozytouch app require specific settings for temperature control?

Thanks for sharing your device model, ARXG18KLLAP. That helps a lot! Regarding your question about whether the Cozytouch app requires specific settings for temperature control, here’s what I can clarify for you:

The Cozytouch app is designed to let you control your heating, including setting different temperatures for various rooms in your home. However, to successfully adjust temperatures remotely, a few conditions must be met:

1. Cozytouch Gateway: You must have one Cozytouch gateway connected and properly linked to your heating devices, including your ARXG18KLLAP unit. This gateway acts as a bridge between your app and physical devices.

2. Device Compatibility: The heating units, like yours, must be compatible and recognized by the Cozytouch system. Your model ARXG18KLLAP is supported as it is part of the Atlantic range controlled via Cozytouch.

3. App and Firmware Updates: Both your Cozytouch app and the gateway’s firmware should be up to date to ensure all features, including temperature adjustments, work as intended.

4. User Permissions: Your Cozytouch app account should have sufficient control permissions. Some setups can restrict user roles, limiting what changes you can make remotely.

5. Device Settings: Your heating devices should be configured to allow remote changes. In some cases, physical controls on devices might lock settings or require switching from manual to remote mode.

6. Proper Network Communication: The Cozytouch gateway and your app need a reliable internet and local network connection to exchange commands effectively.

You can adjust room temperatures individually in the app, for example, setting 19°C in the living room and 20°C in the office, as Cozytouch supports multi-zone control.

If any of these conditions are not met or configured incorrectly, the app may connect but not allow temperature changes.

You can find additional guidance and step-by-step tutorials on the official Cozytouch site here: Cozytouch Tutorials and more info on compatibility and setup on the main site: Cozytouch 1 2 5.

Would you like me to walk you through checking or adjusting any of these settings on your app or gateway? Also, if you have access to your gateway’s web interface, I can help you verify firmware and permissions there.

Are you satisfied with this explanation and guidance so far?
