Bill Porter is an HVACR technician who became an inventor and a manufacturer because he found unitary heat pump wiring confusing, particularly for dual-fuel systems. He has been in the industry over 40 years. About 10 years ago, he decided to create a product that would help other technicians wire dual-fuel heat pumps with minimal guesswork, hassle, and callbacks. Porter said his universal wiring product is made with technicians in mind.
In the April 10 issue of The News, several readers noted that some of the wiring diagrams accompanying the article on “Electricity 101” were flawed. We salute their sharp eyes, and hope their letters help clear up any confusion this seemingly basic article may have caused. From a reader at Tringale Electric, Lexington, MA: “Concerning the diagrams, Figure 2 needs to be corrected in both A and B voltage drops due to the fact that the light, if it is a light, could not be arrived at these voltage drops. Assuming this is a light, I therefore question the values of the voltage in both diagrams. The only way these values could be arrived at would be to replace the light as shown with a single-pole switch. “
