Thermostat having short circuit protection

摘要

An electronic thermostat (7) has a controller (9) which sends control signals to circuitry (11,13) used for activating and deactivating a system for conditioning air (5). Short circuit protection circuitry (15) monitors the circuitry within the thermostat (7) and indicates to the controller (9) 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 (5) for a predetermined period of time.
