These temperature controls are suitable for indoor heating, cooling, and refrigeration applications and have enclosures that meet NEMA 1 for use indoors. These controls can be used with optional, closed tank fittings and immersion wells for immersion applications. They're compatible with two-stage systems. Two-stage systems have two output levels, allow for more energy efficiency than single-stage systems, and cause less extreme changes in temperature. These temperature controls have a capillary tube and sensor that monitor and regulate the temperature of the ambient air, a liquid, or a gas at a distance away from the control. The sensing element is not affected by changes in barometric pressure or cross-ambient conditions to ensure accurate temperature regulation.
