US Patent 11333382 System for heating, ventilation, air-conditioning

Various embodiments include a site controller comprising: a processor; a memory storing a parametrized model for control of a HVAC system; a sensor interface connected to a first sensor; an actuator interface connected to a first actuator; and a cloud interface connected to a remote controller. The processor is configured to: read a first set of sensor signals from the first sensor; process the first set of signals into a set of measured values; transmit the measured values to the remote controller; in response, receive a set of model parameters from the remote controller; read the parametrized model from the memory; read an additional sensor signal from the first sensor; compute an actuator setting signal from the additional signal using the parametrized model and the set of model parameters; and transmit the actuator setting signal to the first actuator.
