Patent number: 11635222Abstract: A damper controller may be configured to send damper control commands to open and close an outdoor air damper to provide free cooling as necessary to satisfy a temperature setpoint inside the building. In some cases, the damper controller may initiate a damper fault test to determine if a damper fault is present. The damper fault test may be based, at least in part, on an outdoor air temperature input, a discharge air temperature input, a commanded damper position, and a damper fault temperature threshold. If a damper fault is determined, the damper controller may send an alert indicative of a detected damper fault. In some cases, the damper fault test results may be weighted to reduce the false positives alerts.Type: GrantFiled: June 9, 2021Date of Patent: April 25, 2023Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Lubos Sikora, Adrienne Thomle, Cory Grabinger, Miroslav Mikulica, Jan Prostejovsky

Patent number: 11474592Abstract: A system that maintains power consumption of a network to a predefined limit. A plurality of elements such as components, nodes and modules may be connected in a daisy chain configuration. Power may be inserted to one or more of the elements which may proceed down the chain to be consumed by the one or more elements. However, there a limit as to the total amount of energy that may be consumed at the same time. Thus, power to the elements may be scheduled so that the limit is not exceeded by at any one time. At the same time, communications may proceed through that chain from element to element. An example of the present system may be a power over a network (PoE).Type: GrantFiled: September 17, 2019Date of Patent: October 18, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Jiri Bazant, Ivo Chromy, Miroslav Mikulica

Patent number: 11466884Abstract: An actuator may include a drive motor, an actuatable output, and a sensor for sensing a first sensed parameter in or around the actuator. The first sensed parameter may have a first sensed parameter value that can change with time. The actuator may also include electronics that may identify a first identified value representative of the first sensed parameter value and increment a first counter value when the first identified value falls within a first range of values, and increment a second counter value when the first identified value falls within a second range of values.Type: GrantFiled: March 12, 2020Date of Patent: October 11, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Miroslav Mikulica, Lubos Sikora, Frantisek Krivanek, David Zeman

Patent number: 10989431Abstract: An actuator is designed to control airflow in HVAC systems by opening and closing a damper. A slippage detector may be secured to a damper shaft to measure movement of the damper shaft. This measured movement may be compared to the expected movement of the damper shaft as indicated by the movement of a rotatable output of the actuator.Type: GrantFiled: December 11, 2018Date of Patent: April 27, 2021Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Miroslav Mikulica, Ondrej Ficner, Ivo Chromy

Patent number: 10935264Abstract: A system having a mixed air box with inputs of return air from a space or spaces of a building, and of outside air. The mixed air box may have an output of discharge air to the space or spaces of the building. The air from the output may be return air that is conditioned with cooling, heat, or outside air. A damper may be situated at the input of outside air to the mixed air box. A temperature sensor may be positioned at the input for outside air and at the output of discharge air. A cooling mechanism may be at the output of the discharge air. The temperature sensor may be downstream from the cooling mechanism. An economizer may have connections with the damper, the temperature sensor and the cooling mechanism.Type: GrantFiled: March 2, 2020Date of Patent: March 2, 2021Assignee: Honeywell International Inc.Inventors: Miroslav Mikulica, Cory Grabinger, Lubos Sikora, Adrienne Thomle, Jan Prostejovsky

Publication number: 20180313559Abstract: An economizer controller with sensor calibration. A controller sensor may be used to measure a parameter. At the same time at the same location of the measurement with the controller sensor, a measurement of the same parameter may be made with a precision sensor. The difference between the two measurements may be saved to a controller memory as an offset. The offset may be used to compensate future measurements of the same parameter by the controller sensor. Additional offsets at various magnitudes may be obtained between the precision and the controller sensors for compensating subsequent measurements by the controller sensor. Measurements with the compensated sensor may be used for calibrating sensors in other economizer controllers, for example, at remote locations in the field.Type: ApplicationFiled: June 28, 2018Publication date: November 1, 2018Inventors: Cory Grabinger, Adrienne Thomle, Miroslav Mikulica
