Publication number: 20210190348Abstract: A system for detection of equipment connections to a thermostat. The thermostat may have one or more terminals with a one-to-one connection to one or more loads respectively of heating, ventilation and/or air conditioning equipment, and one or more terminals with a one-to-one connection to electrical power. One or more detectors may be connected one-to-one to each of the one or more terminals, respectively, for connection to the one or more loads, and the one or more connections to the electrical power. Each detector may be connected to a processor. Each detector may be configured to provide a signal to the processor relative to a corresponding terminal indicating a status of a connection of the terminal to a load or to the electrical power.Type: ApplicationFiled: December 18, 2019Publication date: June 24, 2021Inventors: Jiri Sapak, Mohammad A.

Patent number: 11031200Abstract: A relay assembly that includes a relay, a bypass switch and a controller. The relay includes an electromechanical switch with an open state and a closed state. The bypass switch is operatively coupled in parallel with the electromechanical switch of the relay, and also has an open state and a closed state. The controller is operatively coupled to the relay and the bypass switch, and is configured to switch the bypass switch from the open state to the closed state, then switch the relay between the open state and closed state, and then switch the bypass switch back to the open state. In some cases, the bypass switch includes a TRIAC. The controller may be configured to maintain the bypass switch in the closed state for less than 100 milliseconds before switching back to the open state.Type: GrantFiled: September 21, 2018Date of Patent: June 8, 2021Assignee: Ademco Inc.Inventors: Ever Hernandez, Tracy Lentz, Jean Rouillard

Patent number: 10480805Abstract: A surge protection circuit for an electronic device such as an HVAC controller. In one example, the surge protection circuit may include a first voltage clamp, a second voltage clamp, a resistor, and an output port. The first voltage clamp may provide a first clamping voltage between a power input terminal and a common terminal. The second voltage clamp may provide a second clamping voltage that is less than the first clamping voltage. The resistor may be connected in series with the second voltage clamp, and the series connected resistor and second voltage clamp may be connected in parallel with the first voltage clamp. As such, a surge current at the power input terminal may be split between the first voltage clamp and the second voltage clamp. The amount of surge current that is provided to the second voltage clamp may be set by the value of the resistor.Type: GrantFiled: November 20, 2017Date of Patent: November 19, 2019Assignee: Ademco Inc.Inventors: David Mulhouse, Mohammad Aljabari, Tracy Lentz, Petr Adamik, Tarik Khoury, Steven J.

Patent number: 9803882Abstract: An electronic device may include a housing and a printed circuit board, where the housing has a front cover and a back cover that at least substantially enclose the printed circuit board. In some instances, the back cover may include an outer shell and one or more inward extending walls that extend inwardly toward the printed circuit board. In some cases, the inward extending walls, the outer shell, and the printed circuit board define two or more internal pockets within the housing. The pockets may, in some cases, separate one region of the printed circuit board from another region of the printed circuit board. In some instances, the one or more inward extending walls may be configured to provide support to a back side of the printed circuit board, which may be particularly useful when a touch screen display is mounted on a front side of the printed circuit board.Type: GrantFiled: March 14, 2014Date of Patent: October 31, 2017Assignee: Honeywell International Inc.Inventors: Tarik Khoury, Petr Adamik, Tracy Lentz, Steven J.
