Abstract
A control for a gas fired pool heater is configurable to operate at either a first voltage or a second voltage higher than the first voltage. The control includes an input voltage measurement circuit and an automatic voltage select circuit. The input voltage measurement circuit is configured to be operable for measuring an input line voltage to determine whether the gas fired pool heater unit is connected with the first voltage or the second voltage. The automatic voltage select circuit is configured to be operable for configuring the control for the correct input line voltage as measured by the input voltage measurement circuit.
