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.

Feedback warning system using inducer pulse width modulation signal

A system faults to a return air sensor integrated within a heating, ventilation, and air conditioning (HVAC) unit. The system transmits a signal to a remote sensor. The system determines that a return signal is not received from the remote sensor. The system obtains a temperature reading from the return air sensor. The system determines whether the temperature reading satisfies a temperature setting stored in the memory. In response to determining that the temperature reading does not satisfy the temperature setting, the system enables heating or cooling of the HVAC unit until the temperature setting is satisfied. In response to determining that the temperature reading satisfies the temperature setting, the system disables heating or cooling of the HVAC unit.

System and method for faulting to return air sensor

The present disclosure relates to a control system for a heating, ventilation, and/or air conditioning (HVAC) system. The control system includes a user interface configured to receive a first input indicative of a first expected operating range of a first parameter in a first zone and to receive a second input indicative of a second expected operating range of a second parameter in a second zone. A first set point for the first parameter is within the first expected operating range and a second set point for the second parameter is within the second expected operating range. The control system includes a controller configured to manage operation of the HVAC system and to provide a first alert in response to the first parameter being outside of the first expected operating range and a second alert in response to the second parameter being outside of the second expected operating range.

Zone monitoring systems and methods for a zoning system

A system includes two stage HVAC equipment and processing circuitry configured to receive a call for conditioning and, in response to the call for conditioning, execute a recovery mode algorithm. The recovery mode algorithm is configured to determine an elapsed time between the call for conditioning and an ending of a recent cycle and compare the elapsed time to a threshold time period. The recovery mode algorithm is also configured to, in response to the elapsed time being below the threshold time period, determine a first stage up time based on a first function corresponding to the elapsed time being below the threshold time period. The recovery mode algorithm is also configured to, in response to the elapsed time meeting or exceeding the threshold time period, determine a second stage up time based on a second function corresponding to the elapsed time meeting or exceeding the threshold time period.

An outdoor unit for a building HVAC system includes one or more sensors configured to measure temperature and pressure values. The unit also includes a user interface coupled to the outdoor unit. The user interface is configured to display information to a user. The unit includes a controller including a processing circuit. The processing circuit configured to record the temperature values and the pressure values via the sensors and cause the user interface to display temperature values and pressure values.

The present disclosure relates to a thermostat including a control base configured to couple with and support a portable thermostat, wherein the control base is configured to determine a measure of an environmental condition of a local environment of the control base and communication circuitry of the control base configured to communicate the measure to facilitate control of an HVAC system.

Portable thermostat systems and methods

A controller for a heating, ventilation, and/or air conditioning (HVAC) system is configured to detect an input voltage received as a power supply by the HVAC system, determine the input voltage exceeds a threshold value, and identify a voltage variation event based on determining that the input voltage exceeds the threshold value.

The present disclosure includes a heating, ventilation, and air conditioning (HVAC) system having a zone control panel suitable to control operation of equipment and/or devices in the HVAC system. The zone control panel may include an electronic display to facilitate user interaction with the HVAC system. For example, the electronic display may be used to view, configure, and/or modify operation of the zone control panel and/or other devices implemented in the HVAC system. Further, the zone control panel may use the electronic display to reproduce user interfaces from the equipment and/or the devices. As such, the zone control panel may centralize presentation of relevant information and/or present the relevant information in a familiar manner.

HVAC zone control panel electronic display systems and methods

A non-transitory computer-readable storage medium for a heating, ventilation, and/or air conditioning (HVAC) system includes instructions that, when executed by a processor, cause the processor to receive an input indicative of a user location, perform a verification that the user location is within a determined distance from the HVAC system, and control access to system settings of the HVAC system based on the verification.

Remote access control of HVAC system

A system includes a two stage heat exchanger and a processor. The processor is configured to receive a call from a thermostat and execute, in response to the call, an adaptive staging algorithm. The adaptive staging algorithm is configured to determine, in response to a recent cycle of the two stage heat exchanger being a first stage cycle, a first stage up time of the two stage heat exchanger as a first function of a first value, the first value corresponding to the recent cycle being the first stage cycle. The adaptive staging algorithm is also configured to determine, in response to the recent cycle of the two stage heat exchanger being a second stage cycle, a second stage up time of the two stage heat exchanger as a second function of a second value, the second value corresponding to the recent cycle being the second stage cycle, where the first and second values are different.

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.
