You may just need to reset your AC System’s Power
If your AirTouch is showing error code FFFF, FFFE or FFFC, you may just need to reset your AC system's power.
Check the isolator switch next to your outside fan unit is switched ON. Also, check that the AC circuit in your electrical switchboard is switched ON. Consult an electrician or AC installer if you need help with this.
It could be a wiring issue
If it does not solve the problem, it may be because of a wiring issue between AirTouch and your ducted AC unit that needs fixing or incorrect dip switch settings on the unit gateway that links AirTouch to your AC unit. Consult your AC installer.
Your AC Installer can find the wiring diagrams, and necessary dip switch settings in the installer manuals.
