This control is designed for use on hot water heating systems. It has a coiled element that is immersed directly into the boiler water. This feature gives an unusual speed of response to rapid changes of water temperature thereby preventing thermal lag.
This control has single-pole, double-throw switch action, offering terminals that have open-on-rise switch action as well as close-on-rise switch action. It may be used as a high limit control, low limit control, circulator control, or as a combination low limit and circulator control
