Devices and methods are provided for generating and/or displaying a graphical user interface used to control an energy-consuming system, such as a heating, ventilation, or air conditioning (HVAC) system. Such an electronic device may include, for example, a processor that generates the graphical user interface and an electronic display that displays the graphical user interface. The graphical user interface may include a menu formed from discrete display elements that, owing to the way in which the discrete display elements are shifted into and out of view on the screen, appear to be spatially related to one another.

The present disclosure relates to a heating, ventilating, and air conditioning (HVAC) unit that includes a plurality of lifting lugs coupled to the HVAC unit. The HVAC unit also includes a cable that is threaded through each of the plurality of lifting lugs and coupled to an exterior of the HVAC unit.

An air conditioning device includes a first indoor unit and a second indoor unit interlocking with a safety device as a countermeasure against refrigerant leakage. An installation assistance system for the air conditioning device determines interlock release states of the first indoor unit and the second indoor unit based on information on the air conditioning device, and outputs a determination result. The information on the air conditioning device is information indicating whether or not the first indoor unit and the second indoor unit are short-circuited with the safety device through an interlock line.

An air conditioning system has an air conditioner, which includes an outdoor unit and an indoor unit that configure a refrigerant circuit, and a controller, which controls the running of the air conditioner. The controller does not allow operation of the air conditioner to start in a case where a signal from a ventilation unit that includes a ventilation fan for ventilation and ventilates a target space or a refrigerant leak sensor that detects refrigerant leakage in the target space is not input to the controller. Because of this, even in a configuration where an air conditioner and a ventilation unit are installed independently of each other, operation of the air conditioner can be performed in a state in which there is reliably established a countermeasure such as the ventilation unit being operated when the refrigerant has leaked, and safety and security with respect to refrigerant leakage are reliably ensured.

A climate control system for an animal house having a plurality of climate control outputs such as heaters or ventilation fans has a control unit that regulates operation of climate control outputs. The control unit has a plurality of input terminals and a plurality of sensing devices, each of the plurality of sensing devices located in a different portion of the animal house and connected to one of the plurality of input terminals of the control unit with a connector to provide a signal to the control unit which is used to control the climate in the animal house. Each sensing device includes a thermal resistive sensor and an indicating LED configured to be selectively turned on by the control unit to indicate when the sensing unit is connected to the control unit.

A system and method is provided that facilitates testing a building control system. The system may include at least one rack including: a housing; a terminal panel; and a plurality of slidable field panels mounted in the housing in side-by-side relation. The terminal panel may includes a plurality of connection terminals that are wired to respective component terminals of a plurality of components mounted to the field panels. Each field panel may be configured to independently slide at least partially out of a front side opening of the housing via a plurality of slides mounted to each field panel and to the housing. The system may also include at least one story board including: a schematic illustration mounted to a frame that depicts components of a heating, ventilating, and air conditioning (HVAC) system; and a plurality of instruments mounted to the frame at locations on the illustration adjacent the depicted components of the HVAC system, which instruments receive inputs from and provide outputs to the building control system through wires connected to the connection terminals of the at least one rack, so as to mimic aspects of an HVAC system in order to test the configuration of the building control system in the at least one rack.

To enable easy access and lead wire routing during maintenance, without causing ventilation hindrance. An electrical component box 14 is provided on the side of the outer surface of a lateral plate 113 of an outer shell 11 of a body unit, and a cable storage part 15 for storing a drawing section of a lead wire 143 drawn from the electrical component box 14 and guiding the drawing section in a predetermined direction is disposed on the side of the inner surface of the lateral plate 11.

A smart-home device may include wire connectors that couple to an inductive power coil and a load, one or more solid-state switching elements having a first operating state in which they create a connection between the wire connectors and a second operating state in which the connection is interrupted. The smart-home device may cause the switching element(s) to operate in the first operating state to power the load; detect an anomaly from measurements from power monitoring circuitry; cause the switching element(s) to operate in the second operating state for at least a first time interval; and after the expiration of the first time interval, cause the one or more switching elements to operate in the first operating state and determine whether the anomaly is still present.

Disclosed are exemplary embodiments of apparatus and methods for facilitating installation and/or connection of controllers such as thermostats. In an exemplary embodiment, an apparatus for facilitating installation and/or connection of a controller in a climate control system generally includes a communication device configured to execute software instructions to receive user input describing a wire arrangement where the controller is to be installed for use in the climate control system. Based on the user input, the communication device identifies a configuration of the climate control system and specifies wiring connections between the wire arrangement and controller.

Various arrangements for installing or configuring an electronic device are presented. The device may determine which wire connectors of a set of one or more wire connectors have a wire attached. A user inquiry may be output based on the electronic device identifying the wire connector with which the wire has been connected. The electronic device may be operated based on the response to the user inquiry and the electronic device identifying the wire connector with which the wire has been connected.
