Abstract
A thermostat includes a power stealing circuit selectively configured to provide power to the thermostat and to circuit(s) ancillary to the thermostat from power source(s) external to the thermostat, without requiring a common or neutral connection between the thermostat and the power source(s). Exemplary embodiments also are disclosed of a climate control system that includes such a thermostat. This thermostat can power-steal off of existing load wires (e.g., a W and/or Y terminal, etc.) and can provide power for a continuous backlight and/or other device (e.g., a remote sensor and/or low-power transceiver, etc.).

17. A method of providing climate control, the method comprising:
-
connecting a thermostat with a climate control system, the thermostat having a power stealing circuit selectively configured to provide power to the thermostat and to one or more climate control system circuits ancillary to the thermostat from a power source external to the thermostat; and operating the climate control system using the thermostat; the method performed without having to connect the thermostat, through a common or neutral wire connection, with the external power source. - View Dependent Claims (18)
