Questions & Answers


does this assy. come with a low voltage line? It appears to be wound up at bottom of picture

Asked by mike March 26, 2019

Our line sets come with wiring used for both the communication and the power. The indoor units which require 115V or 230V depending on which unit you purchase, are powered off the outdoor unit. The communication is low voltage DC, but runs off the same size wire. The wiring is 14 gauge – 4 conductor, 600V rated stranded copper wire.
