摘要： The present disclosure includes a thermostat for controlling HVAC equipment of a building based on occupancy of the building. The thermostat includes an occupancy sensor configured to detect a presence of an occupant. The thermostat includes a processing circuit. The processing circuit can receive occupancy data for one or more points in time from an occupancy sensor. The occupancy data indicates the presence of an occupant at the one or more points in time. The a processing circuit can train an occupancy model based on the occupancy data, wherein the occupancy model predicts a probability of the presence of the occupant

摘要： An air conditioner includes a controller that controls an inverter on the basis of an instruction received by a receiver. The controller includes: a rotational speed acquisition unit that acquires a specific rotational speed corresponding to a combination of an air volume and an air speed; a correction value acquisition unit that acquires a specific correction value by determining an operation mode, presence or absence of a power saving mode, and presence or absence of a sleeping mode; and a selection unit that selects three-phase operation when the specific rotational speed is lower than a threshold calculated by adding the specific correction value to a fixed value, or selects two-phase operation when the specific rotational speed is higher than or equal to the threshold.
