The A70 Series heavy-duty temperature-limit controls incorporate a vapor charged sensing element. A70G, A70H, and A70K have a four-wire, two-circuit contact block that contains two isolated sets of contacts. The contacts are designed to transfer at set point so that when the main contact opens, the auxiliary contact closes simultaneously. Typical applications include shutdown of a ventilation system and BAS alarm indication upon low or high temperature.
