    Abstract: Systems and methods are disclosed for validating the installation and operation of a fault detection and diagnostic module that monitors a component of an HVAC system. A remote diagnostic server is in operative communication with the HVAC system, and with the fault detection and diagnostic module. A user device communicates data to the remote diagnostic server that defines an association between the fault detection and diagnostic module and the HVAC system. The remote diagnostic server initiates an installation validation by sending a command to the HVAC system that causes the monitored component to initiate an event that is expected to be reported by the fault detection and diagnostic module. For example, a fan motor is turned on. If correctly installed, the fault detection and diagnostic module senses the event, and reports the event to the remote diagnostic server, which confirms the association. The remote diagnostic server sends a message to the user device indicating the result of the validation.

    Abstract: Improvements to an HVAC thermostat include a sleep-enhancing feature which regulates the target temperature of the HVAC system according to a temperature profile which complements the natural changes in body temperature of a person during sleep. The timing of the temperature profile is advanced to cause room temperature to decrease before the natural decrease in body temperature is expected to occur, thereby helping lead a person into sleep without the use of pharmaceuticals or other artificial sleeping aids. The temperature profile causes room temperature to increase towards the end of the sleep period, thus avoiding disruptions of sleep when body temperature is lowest or during REM stages of sleep when the human body's ability to thermo-regulate is diminished. The rate of change of the target environment temperature is controlled to further enhance the quality and duration of sleep.

    Abstract: An HVAC system includes an indoor unit, an outdoor unit, a thermostat, and a remote control device. The indoor unit comprises a first variable speed drive (VSD) to control a speed of HVAC rotary components within the indoor unit, and the outdoor unit comprises a second VSD to control a speed of HVAC rotary components within the outdoor unit. The thermostat in communication with the indoor unit and the outdoor unit comprises a communication interface, and a system controller in communication with the communication interface. The remote control device transmits a signal to the system controller to alter the speed of the HVAC rotary components, where the HVAC rotary components operate at a high speed mode which is above the preset speed limit of the respective HVAC rotary component to achieve an enhanced cooling mode.
