Troubleshooting

Can't find the NH-AC- hotspot

The hotspot is only up during a pairing window (15 minutes).

• Set the AC again with the remote: Cool, 30 °C, Low fan. If it's already on that setting, change the temperature and back.
• Check that the AC is on and the controller is connected to it.
• Once the hotspot appears, finish setup within 15 minutes.

New router or WiFi password

Use either method to reopen the hotspot, then set up again with Local setup:

• Status page: log in and tap "Reset WiFi".
• Power cycling: cut power to the controller and restore it, 5 times in a row, each time on for less than 10 seconds. Use this when the controller can't reach the old network and the status page won't open.

Both clear only the WiFi settings. Completing setup again on the hotspot asks for the admin password and connection mode again.

Forgot the admin password

Reopen the hotspot by power cycling, complete Local setup again and choose a new admin password.

The status page won't open

• Make sure your phone or computer is on your home WiFi, not the controller's hotspot.
• Some Android phones and older Windows versions can't open .local addresses; use the IP address from your router's device list.
• If the page shows "Can't reach the device — it may be restarting… retrying", the controller may be restarting. Give it a moment.

Home app shows "No Response"

• Check that the controller has power and is on your home WiFi (open the status page to confirm).
• If you changed the HomeKit setting, make sure you tapped "Restart" to apply it.
• Under "HomeKit" on the status page, check that HomeKit is running. If it says "HomeKit isn't running. Turn it on in Settings, then restart the device.", follow that.

The AC has a new owner (NH app)

This applies only to ACs used with the NH app (cloud mode). If the previous user didn't remove the AC from their app, the new user can take it over:

1. Open a pairing window with the remote (Cool, 30 °C, Low fan).
2. While it's open, turn the AC off and on with the remote 5 times within 30 seconds.
3. Add the AC in the NH app. The previous user loses access and is notified.
