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. “
One other way to wire multiple zones is with the use of zone valves. A zone valve is a motorized solenoid valve with an end switch. The thermostat for each zone is wired through a 24-V transformer to the zone valve. A mechanical end switch is wired to the thermostat terminals of the boiler operating controls. When choosing a transformer for zone valves, make sure that the VA (volt amps) rating of the transformer is sufficient to run the zone valves attached to it.
