All wiring must comply with the National Electrical Code™ (NEC) and local codes.
Ensure that 24 Vac power supplies are consistent in regards to grounding. Avoid sharing 24 Vac
between controllers.
Avoid over tightening cable ties and other forms of cable wraps. This can damage the wires
inside the cable.
Do not run communication cable alongside or in the same conduit as 24 Vac power. This
includes the conductors running from TRIAC-type inputs.
In open plenums, avoid running wire near lighting ballasts, especially those using 277 Vac.
Use same communication wire type, without terminators, for the zone sensor communication
stubs from the Symbio 210 controller IMC terminals to the zone sensor communication module.
Zone Sensor communication wiring length limits of 300 ft. (100 m).
