  • Method for sensing welded contacts on a switching device
    Patent number: 9897656
    Abstract: A method for sensing a welded relay contact when breaking both sides of a power line on a HVAC device including the steps: applying a first signal to one of a pair of switching devices; electronically sensing a second signal, with a sensing device, whether the other of said two switching devices is welded closed; and sending a third signal from the sensing device indicative of whether the other of said two switching devices is welded closed.
    Type: Grant
    Filed: April 30, 2014
    Date of Patent: February 20, 2018
    Assignee: Carrier Corporation
    Inventors: Jeffrey P Lothamer, Daniel L Kelly

  • REMOTE SENSOR CONFIGURATION
    Publication number: 20140172350
    Abstract: Embodiments are directed to receiving, by a device, an identification of a coupling configuration associated with at least one sensor via a user interface, sensing, by the device, a sensed parameter associated with the at least one sensor, calculating, by the device, a translated parameter based on the sensed parameter, and mapping, by the device, the translated parameter to a temperature.
