Abstract
In one embodiment, an HVAC system includes a first control unit communicatively coupled to a first plurality of HVAC units and a second control unit communicatively coupled to a second plurality of HVAC units. The first control unit may connect to the second control unit using a Wi-Fi direct protocol to create an HVAC control network. The first control unit and second control unit may each detect and connect to a Wi-Fi network comprising a wireless access point. The first and second control units may then communicate concurrently over both the HVAC control network and the Wi-Fi network. The first control unit may detect a user device over the Wi-Fi network, receive a first command from the user device over the Wi-Fi network, and communicate the first command to the second control unit over the Wi-Fi network. The first control unit may detect a communication failure in the Wi-Fi network, communicate with the user device over the HVAC network using the Wi-Fi direct protocol, receive a second command from the user device over the HVAC control network, and transmit the second command to the first plurality of HVAC units.
