Communication Wire Info.
💡 Note: If you have a Symbio Condenser paired with a Symbio Air Handler with Model Number Digit 15 = D (2 Stage Airflow/Single Zone VAV) you must run BOTH Adapter Board J15-3 & 4 to Relay Board J4-3 & 4 and Adapter Board J16-1 & 2 to Relay Board J7-1 & 2 shielded twisted pair!
Use the correct communication wire to ensure reliable communication between the Condenser and the Air Handler.
Recommended wire Part Number (s) are below.
Other wire may be used if it conforms to the following physical characteristics:
- Twisted pair (2-conductor) plus shield.
- Characteristic Impedance: 100 and 130 ohms.
- Distributed capacitance between conductors: < 100 pF/m.
- Distributed capacitance between conductor and shield: < 200 pF/m.
- A foil or braided shield is acceptable.
- Wire diameter: 22 to 18 AWG
