Abstract
A gas-powered water heater includes means for stepping down a line voltage from a receptacle remote from the tank, means for using the stepped down voltage to provide a low voltage, and means for using the low voltage to sense conditions pertaining to the heater and to control heater operation based on the sensed conditions. Using a plug-in transformer to provide power for microprocessor control makes it unnecessary to install a line voltage line to the heater.
