Abstract: A thermostat is provided that receives one or more inputs from at least one heating system of a climate control system, and initiates an appropriate action in response to the input. The thermostat can turn off a heat pump providing substandard heat and responsively turn on a fuel-fired auxiliary furnace. The thermostat may discontinue further operation of the auxiliary furnace upon receiving an operating error signal associated with the auxiliary furnace, and responsively turn on the heat pump to provide for continued heating. The thermostat may also discontinue operation of the fuel-fired furnace and turn on a circulating fan in response to an input signal indicating a furnace high-temperature or a carbon monoxide presence.

Abstract: A thermostat is provided that comprises a touch-sensitive transparent membrane adapted to be affixed over a display, where the transparent membrane has a plurality of membrane switches. The thermostat comprises a microprocessor in communication with the plurality of membrane switches, and has a memory for storing a program for controlling the operation of the climate control system. The thermostat further comprises a display device responsive to the microprocessor for displaying a first screen having at least a first user-interface icon associated with at least one membrane switch, where in response to the user touching the membrane switch associated with the first user-interface icon the display device displays a second screen having at least a run user-interface icon and a schedule user-interface icon.

Abstract: A thermostat is provided comprising a first connector for connecting to an air conditioner, a second connector for connecting to either a conventional heater or a heat pump reversing valve, and a selection means for selecting from at least a first mode of operation and a second mode of operation. The first mode of operation is configured to establish cooling by providing an on signal to the first connector and to establish heating by providing an on signal to the second connector. The second mode of operation is configured to establish cooling by providing an on signal to the first and second connectors, and heating by providing an on signal to the first connector but not the second connector. When the second mode is selected and the second connector is connected to conventional heating, the thermostat detects when both the conventional heating and air conditioning are operating simultaneously during cooling.

Abstract: A thermostat for controlling a climate control system is provided that comprises a network interface for establishing an internet connection with a website of a remote service provider, and a microprocessor for controlling the operation of a climate control system. The microprocessor is in communication with the network interface for establishing an internet connection and receiving user-specified information from a remote service provider that maintains a user-profile of information requested by the user. The thermostat further comprises a display device responsive to the microprocessor for displaying user-specified information received via the network controller from the remote service provider.

Abstract: A digital thermostat having a plurality of user input buttons, a display, a battery, a real time clock, a memory and a processor that is capable of receiving initial time and date information and storing the information in memory. The initial time and date information is then provided to the real time clock for maintaining the current time in the thermostat. The user is prompted by the program to select and enter a time zone setting, after which the current date and local time is automatically set and shown on the thermostat display.
