Abstract: In an aspect, an HVAC system includes an inducer motor to provide combustion airflow, and a pressure sensor to measure an output airflow pressure of the inducer motor. The HVAC system may initiate the inducer motor, and receive a pulse width modulation (PWM) signal from the inducer motor, wherein the PWM signal indicates a PWM signal of the inducer motor corresponding to a predetermined airflow pressure of the inducer motor and measured by the pressure sensor. The HVAC system may compare the PWM signal to a baseline value, and control the inducer motor based on the comparing of the PWM signal to the baseline value. The HVAC system may also generate a status notification of the combustion airflow of the HVAC system in response to the comparing the PWM signal to the baseline value.

Abstract: A heating, ventilation, or air conditioning (HVAC) system includes a headless thermostat device and an adapter unit. The headless thermostat device includes one or more circuits configured to receive a control input from a user device via a local wireless network and generate a control signal for HVAC equipment based on the control input. The adapter unit includes one or more circuit configured to receive the control signal from the headless thermostat device via the local wireless network and provide the control signal to the HVAC equipment for operation of the HVAC equipment in accordance with the control input.

Abstract: The present disclosure provides systems, apparatuses, and methods for monitoring building efficiency by a heating, ventilation, and air conditioning (HVAC) system. In an aspect, an HVAC unit including a memory and a processor coupled with the memory is disclosed. The processor may be configured to establish a current building efficiency state value of a current run cycle of the HVAC system. The processor may also be configured to determine an building efficiency state deviation value based on a difference between an average building efficiency state value of a set of previous building efficiency state values and the current building efficiency state value. The processor may further be configured to determine whether the building efficiency state deviation value satisfies a building inefficiency threshold. The processor may also be configured to provide an indication including an inefficiency status to a device associated with the HVAC system based on a determination that the current building efficiency state satisfies the building inefficiency threshold.

Abstract: A temperature control system receives, from a remote user device associated with a user, a user designation designating a temperature sensor from among a plurality of temperature sensors. The temperature control system selects, in response to receiving the user designation, the temperature sensor as a primary temperature sensor for controlling an ambient condition. The temperature control system receives a primary temperature measurement from the primary temperature sensor, and performs a primary temperature control based on the primary temperature measurement. The temperature control system may further receive secondary temperature measurements from secondary temperature sensors, and perform a secondary temperature control based on the secondary temperature measurements.
