A system comprises a primary unit and a plurality of secondary units each having a unique unit number. The primary unit is configured to communicate a command to each secondary unit with instructions to reply during a time window. The primary unit is also configured to receive a reply communication indicating the secondary unit's unique unit number from at least one of the secondary units, and determine an address to assign to the replying secondary unit based at least in part on the received unique unit number.

An integrated device in an HVAC system is configured to modify an environmental condition of a building. The integrated device includes a valve configured to regulate a flow of a fluid through a conduit and an actuator. The actuator includes a motor and a drive device. The drive device is driven by the motor and coupled to the valve for driving the valve between multiple positions. The integrated device further includes a processing circuit coupled to the motor. The processing circuit is configured to detect device identifying information for the valve or the actuator and to detect the integrated device location within the building.

An air conditioner unit may include a housing, an outdoor heat exchanger, an indoor heat exchanger, a compressor, a sterilization light assembly, and a controller. The housing may define an indoor portion and an outdoor portion. The housing may further define an exhaust outlet downstream from the indoor portion to exhaust air therefrom. The sterilization light assembly may be disposed within the indoor portion. The controller may be in operable communication with the indoor fan and the sterilization light assembly. The controller may be configured to initiate a sterilizing operation. The sterilizing operation may include directing activation of the indoor fan to motivate air through the indoor portion, detecting activation of the indoor fan to motivate air through the indoor portion, and directing activation of the sterilization light assembly to transmit an ultraviolet light emission within the indoor portion based on detected activation of the indoor fan.

This disclosure aims to provide a technique for improving the accuracy of prediction. A first trained model for inferring labels for measurement data is generated based on a first data set. The first data set includes: combined data that are a combination of first measurement data, which are related to a first air conditioning apparatus, and labels set for the first measurement data; and second measurement data related to the first air conditioning apparatus.

A system and method for determining HVAC set points are provided. A present season is determined. An allowable temperature comfort range for each occupant in a room in a space is also determined. For each room, an energy saving set point temperature is calculated for the space based on the allowable temperature comfort range for that room. A set point temperature for the space is determined based on the energy saving set point temperatures for each of the rooms in the space. The set point temperature is provided to a thermostat or HVAC system to regulate temperature in the building.

A control system for a HVAC system for a structure and including a blower that flows air over an indoor heat exchanger. The control system may include a first input device, a first sensor, and a processor in electronic communication with the first input device, the first sensor, and the blower of the HVAC system. The first input device may be operable to accept a zoning mode selection. The first sensor may be sensor operable to measure a first temperature at a first location within the structure. The processor may be programmed to determine a cooling or heating demand on the HVAC system based on an input temperature and the first measured temperature. The processor may be further programmed to adjust an air flow rate produced by the blower based on the demand on the HVAC system and the zoning mode selection.

A humidifying device includes an air inlet, an internal air passage through which air taken in from the air inlet passes, a first thermometer that measures a temperature of the air taken in from the air inlet, a first hygrometer that measures a humidity of the air taken in from the air inlet, a cooler installed in a path of the internal air passage, and a cooling control unit that controls the cooler. The cooling control unit changes a cooling intensity of the cooler in a case where values measured by the first thermometer and the first hygrometer are out of a predetermined range.

An air conditioning appliance includes a heat exchanger disposed within a housing. A compressor is in fluid communication with the heat exchanger. The compressor is operable to circulate refrigerant through the heat exchanger. A fan is disposed within the housing. The fan is operable to flow air over the heat exchanger. A circuit board is disposed within the housing, and a heat sink is mounted to the circuit board. The heat sink positioned such that the fan flows air over the heat sink during operation of the fan. A temperature sensor is disposed at one or both of the heat sink and the circuit board. A controller is in operative communication with the temperature sensor. The controller is configured to receive a signal from the temperature sensor corresponding to a temperature measurement and to activate an alert at least partially in response to the temperature measurement exceeding a temperature limit.
