• Most suitable model can be selected from the variations of wide temperature range with either adjustable or fixed differential. Narrow differential is further advantageous. • Sensing elements are air sensed and liquid sensed type depending on control media. Also, sensing element can be selected from remote or direct type depending on application. • Single pole double throw contacts allows use for either heating or cooling application, with large contact rating as well. • Adjusting mechanism is driver adjusting type as standard on delivery, but a knob assembly and a concealed plate are also supplied as standard accessories.

Models “set high” The dial indicates the high switch point (훿 – close, 훿 – open). The low switch point (훿 – open, 훿 – close) is obtained by deducting the differential from the high switch point. Arrow mark indicates a direction of switch action on temperature increase.
