1. A thermostat for controlling activation of a system for conditioning air, said thermostat comprising:
- activating circuitry connected to said system for conditioning air for activating said system for conditioning air;
a controller connected to said activating circuitry, said controller generating a control signal for said activating circuitry so as to cause said activating circuitry to activate or deactivate said system for conditioning air; and
short circuit protection circuitry connected to said controller, said short circuit protection circuitry indicating to said controller when a short circuit condition has occurred so that said controller sets the control signal to deactivate said activating circuitry for a predetermined period of time.

Abstract
An electronic thermostat having a short circuit protection feature has a controller which sends control signals to circuitry used for activating and deactivating a system for conditioning air. Short circuit protection circuitry monitors the circuitry within the thermostat and indicates to the controller when a short circuit has occurred. When a short circuit is detected, the controller sets its control signal to deactivate the system for conditioning air for a predetermined period of time.

12. A method for controlling a system for conditioning air comprising the steps of:
-
normally activating the system for conditioning air by a control signal sent from a controller when a sensed temperature varies from a setpoint temperature; detecting a short circuit condition in circuitry associated with the system for conditioning air; and setting the control signal from the controller so as to deactivate said system for conditioning air when a short circuit is detected. - View Dependent Claims (13, 14, 15)
