Patent number: 11353225Abstract: A fan coil thermostat includes a controller that implements a control algorithm that includes an Auto fan speed mode. The controller is programmed to permit a user to manually select a fan speed setting using the user interface. In response, the controller initiates a timer, and automatically returns to the Auto fan speed mode once the timer expires.Type: GrantFiled: December 2, 2016Date of Patent: June 7, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Levi H. Geadelmann, Daniel J. Sullivan, Camel Zhang, Gary Yang, Angela Zhao

Patent number: 10731888Abstract: Fan coil thermostats can provide energy savings by, for example, not unnecessarily heating and/or cooling an unoccupied room or other space. Fan coil systems employing such a fan coil thermostat may be more energy efficient. A fan coil system may include a fan coil that is configured for fluid communication with a source of heated fluid and/or a source of cooled fluid, a valve that controls fluid flow through the fan coil, a fan that blows air across the fan coil and a fan coil thermostat. The fan coil thermostat may include a controller that implements a control algorithm that may include an unoccupied temperature setting. The controller may be programmed to permit a user to enter a user-chosen temperature setting. In response, the controller may initiate a timer, and may automatically return to the unoccupied temperature setting once the timer has expired.Type: GrantFiled: May 11, 2018Date of Patent: August 4, 2020Assignee: Honeywell International Inc.Inventors: Daniel J.

Publication number: 20170082311Abstract: Fan coil thermostats can provide energy savings by, for example, not unnecessarily running a fan for longer than necessary or at a higher speed than necessary. Fan coil systems employing such a fan coil thermostat may be more energy efficient. A fan coil system may include a fan coil, a valve that controls fluid flow through the fan coil and a fan that blows air across the fan coil. The fan coil thermostat may include a controller that implements a control algorithm that may include an Auto fan speed mode. The controller may be programmed to permit a user to manually select a fan speed setting using the user interface.

Patent number: 9157646Abstract: Methods and apparatus for automatically changing between heating and cooling in an HVAC system. In one example, an HVAC controller may monitor the temperature of an inside space of a building, and may switch the HVAC system to cooling when the temperature of the inside space rises above a high switch-point temperature, and may cool the inside space to at least below the high switch-point temperature. The HVAC controller may also switch the HVAC system to heating when the temperature of the inside space falls below a low switch-point temperature and may heat the inside space to at least above the low switch-point temperature. In some cases, after switching to heating or cooling, the HVAC controller may cause the HVAC system to heat or cool the inside space, respectively, to substantially the set-point temperature.Type: GrantFiled: September 13, 2010Date of Patent: October 13, 2015Assignee: Honeywell International Inc.Inventors: Amy L. Anderson, Gary Yang, Camel Zhang, Angela Zhao, Paul Wacker, Nicholas Dalsin

Publication number: 20120061068Abstract: The present disclosure describes methods and apparatus for automatically changing between heating and cooling modes of an HVAC system, sometimes using a single or common set point in both modes. In an illustrative but not limiting example, an HVAC controller may monitor the temperature of an inside space of a building, and may switch the HVAC system to a cooling mode when the temperature of the inside space rises above a high switch-point temperature, and may cool the inside space to at least below the high switch-point temperature. The HVAC controller may also switch the HVAC system to the heating mode when the temperature of the inside space falls below a low switch-point temperature and may heat the inside space to at least above the low switch-point temperature. In some cases, after switching to the heating mode, the HVAC controller may cause the HVAC system to heat the inside space to substantially the set-point temperature.Type: ApplicationFiled: September 13, 2010Publication date: March 15, 2012Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Amy L.
