• Signal cable of outdoor unit and indoor unit: 3 x 1.5 mm² (This cable
is required only for the outdoor unit configured with a temperature
control intelligent monitoring board, that is, the 52273539 or
52273541 outdoor unit. This cable is not required for other outdoor
units.)
When the NetCol8000-A045/A055/A060 indoor unit is used, prepare
one group of outdoor unit cables for each indoor unit (if two indoor
units are used, prepare two groups of outdoor unit cables). When
the NetCol8000-A090/120 indoor unit is used, prepare two groups of
outdoor unit cables for each indoor unit.
