A method in a heating, ventilation, or air conditioning (HVAC) system includes retrieving a control input from a remote computing system via a cellular network responsive to determining that a connection to a local wireless network cannot be established and generating a control signal for HVAC equipment based on the control input or generating a control signal for HVAC equipment by executing a backup control algorithm responsive to determining that a connection to a local wireless network cannot be established.

Backup control for HVAC system with headless thermostat

A heating, ventilation, or air conditioning (HVAC) system includes a headless thermostat device and an adapter unit. The headless thermostat device includes one or more circuits configured to receive a control input from a user device via a local wireless network and generate a control signal for HVAC equipment based on the control input. The adapter unit includes one or more circuit configured to receive the control signal from the headless thermostat device via the local wireless network and provide the control signal to the HVAC equipment for operation of the HVAC equipment in accordance with the control input.
