The updated Universal Products Quick Reference Guide is a free, pocket-sized reference card containing information about the Universal Products line of replacement products, including the company's thermostats. Specifications are given for each universal replacement product, as well as a cross-reference to the company's older products and competitive models. Products include universal gas valves and ignition modules, including spark modules, silicon carbide igniter replacements, and the nitride igniter upgrade kit. The reverse side of the guide shows the 90, 80, and 70 series electronic programmable and nonprogrammable thermostats. According to the manufacturer, thermostat selection is made easier through color-coding, sell-up feature sets, and complete specifications and terminal lists for each thermostat in each series.
