The VAV compact controllers are supplied with one prewired 6-core power supply
and communication cable. The VAV modular controller is supplied with one
prewired 6-core power supply and communication cable and one prewired 4-core
connection cable for OpenAir 3P damper actuators.
All interconnected devices must be connected to the same G0.
