MagIQtouch not finding Invertair KACV/KCHV add on during system configuration - Invertair cable Pt# 865256



If experiencing communication faults or MagIQtouch controller not finding appliance when installing a KACV/KCHV Invertair Add-on to a TQ ducted gas heater,


  • Check 5m long communication cable ( part #865256) that connects between the heater and the indoor coil of the add on. 
  • Check that the unused conductors at the indoor coil end of the cable ( flat white connector) do not touch each other.
  • Suggest the two unused cables are carefully cut to different lengths and electrical tape applied to prevent conductors touching earth or one another. 

  • Attached image shows the unused black and white conductors 



Cut unused conductors at diffferent lengths and insulate so that they can't touch each other or short circuit to earth.
