Shielded Twisted Pair Cable

A shielded twisted pair cable is required for Symbio condenser installations where the indoor air
handler is variable speed supply fan (VFD) and/or electric heat. See Air Handler and Condenser
pairing information for more details regarding shield twisted pair cable installation requirements.
Trane Purple Wire is recommended when shielded twist pair cable is required (see the following
table).
Alternate shield twisted pair cable can be used if it conforms to the following physical
characteristics:
