What to do if mobile can't control Johnson ETNA?
- GGabrielle JohnsonAug 3, 2025
If the Johnson Air Conditioner (WLAN module) is rebooted and the app displays 'Device remove,' ignoring this confirmation will cause your mobile device to lose control permission. You'll need to reconnect the air conditioner via CF mode. Also, in case of a power failure, the mobile device will lose control permission for 3 minutes after the power failure. If you still can't control the app after power is restored, reconnect the air conditioner via CF mode.
