  • Device and method for recording air conditioning system information
    Patent number: 8117862
    Abstract: HVAC apparatus is configured to include a control system with a controller which may be connected directly to a personality module for transferring information stored in the controller related to historic operating conditions of the apparatus to the module, or information may be transferred to the controller from the module to configure the controller for operation of the apparatus at selected operating conditions of temperature, pressure and blower motor speed, for example. The personality module includes a memory circuit and a connector for releasably connecting the module to the control system of the apparatus for transferring information between the module and the controller.
    Type: Grant

  • Thermostat with energy saving backlit switch actuators and visual display
    Patent number: 7299996
    Abstract: An air conditioning system thermostat includes a visual display and plural switch actuators, respectively backlit by an electroluminescent lamp and LED light sources mounted on a circuit board disposed in a thermostat housing. A control circuit causes at least one switch actuator to be illuminated continuously and the light sources for the display and the remaining switch actuators are illuminated in response to actuation of any one of the switch actuators. Switch contact elements mounted on the switch actuators and the circuit board provide advantageous positioning of the LED light sources for the switch actuators. An energy savings switch actuator allows the control circuit to directly assume setback temperature settings in response to a first actuation and a second actuation resets the thermostat to the initial user set temperature settings.
