You can perform a factory reset of the console:

• Press and hold the power button to force shutdown.

• Press and hold Power + Volume Up for approximately 20 seconds to open the Android recovery menu.

• Use volume keys to navigate to Wipe Data – Factory Reset, then press power to confirm.

Swipe to the Android home screen, then go to:

Settings > Security > Screen Lock to set a PIN, password, or pattern.

Connectivity Issues

1. Wi-Fi keeps disconnecting on the console.

• AirTouch 2+ & AirTouch 4:

  • Connect only to a 2.4GHz Wi-Fi network.

  • Ensure band steering is disabled on your router.

• AirTouch 5:

  • Restart the console (hold power button).

  • Disconnect and reconnect the controller.

  • If the issue persists, contact a service technician to arrange an SD card software update or console replacement.

2. AirTouch 5 app isn’t loading and returns to Android screen.

This indicates a communication error between the console and the main control module.

Check and reseat the RJ12 cable between the two units.

3. Error: “Communication Timeout – Check Cable”

Inspect and firmly reseat the RJ12 cable connecting the console to the main module.

Console & Display Issues

1. AirTouch 5 console screen is blank.

Check the following:

• Console power supply is connected.

• AC circuit breaker is ON.

• Wall isolation switches are ON.

2. Console not responding to touch.

• If under warranty: Request a replacement.

• If out of warranty: A new console can be purchased.

Air Conditioning & Zoning

1. Just installed 3 A/C units, but one is not showing on the console.

• Confirm wiring is correct.

• Check DIP switch settings on all gateways.

• If unresolved, escalate to a service technician.

2. Fault code FFFF appears after install.

This is a communication error between the AC indoor unit and the AirTouch gateway.

• Refer to the FFFF Troubleshooting Guide, or

• Escalate to a service technician.

3. Other fault codes appear (not FFFF or FFFE).

These are typically air conditioner-specific errors.
Check the fault code against the AC manufacturer’s guide. In most cases, the issue should be resolved by the AC installer or manufacturer.

Sensors & Wireless Devices

1. All ITS sensors have disconnected.

Most common cause: Power outage or electrical surge.

Steps to resolve:

• Turn off the main control module using the AC circuit breaker or isolation switch.

• Wait at least 1 minute, then power back on.

• ITS sensors should reconnect automatically within a few minutes.

• If not, follow this guide: Pairing ITS Sensors

2. Can I connect wired zone temperature sensors to AirTouch 5?

No. AirTouch 5 supports only wireless Intelligent Temperature Sensors (ITS).

3. Can I use AirTouch 4 sensors with AirTouch 5?
