Auxiliary Control Wiring

The interconnection of auxiliary control wiring for remote heat exchangers (condensers and fluid cool-
ers) requires the connection of two (2) - 18-gauge wires for installations up to 150 feet (45 m) or
16-gauge wires for installations from 151 feet (46 m) up to 200 feet (61 m) from the electrical control box
of the indoor evaporator to the electrical control box of the remote heat exchanger. Condensing units
(i.e., where the compressor(s) are mounted in the remote heat exchanger) will typically require (4) or
more wiring connection points and may require heavier gauge wire. In this case, the installing contrac-
tor must follow the applicable electrical codes to determine the required wire gauge.
Because of the wide variety of indoor evaporators and remote heat exchangers offer by Data Aire, the
installing contractor must refer to the schematic which is provided inside the electrical control box of
each unit, for the required auxiliary control wiring interconnection terminal points.
