Abstract
An electrical system for controlling the operation of a heat exchanger unit, thermostat therefor and methods of making the same are provided, the system having a first electrical power source, the system having an electronic control logic unit operatively interconnected to the first power source to operate the heat exchanger unit in relation to data selectively entered into the electronic control logic unit and being maintained by the electronic control logic unit as long as the electronic control logic unit is receiving electric power, the system having a second electrical power source for supplying electrical power to the electronic control logic unit to maintain the data thereof when the first electrical power source ceases to supply electrical current to the electronic control logic unit even for a relatively long period of time, the second electrical power source comprising a capacitor unit.
