Abstract
In one embodiment, an HVAC system includes a first control unit communicatively coupled to a first plurality of HVAC units and a first interactive display. A second control unit communicatively coupled to a second plurality of HVAC units and a second interactive display. The first control unit is operable to detect and connect to the second control unit using a Wi-Fi direct protocol to create an HVAC control network that is designated as a primary communications network. The first control unit further operable to detect a Wi-Fi network including a wireless access point. The first control unit operable to re-designate the HVAC control network as a secondary communications network and to designate the Wi-Fi network as the primary communications network. The first control unit may also detect and connect to the second control unit over the Wi-Fi network, wherein the first control unit may receive a first temperature change request from the first interactive display and transmit the first temperature change request to the second control unit over the Wi-Fi network.
