A11 Series low temperature cutout controls are available with Single-Pole, Double-Throw (SPDT) or Single-Pole, Single-Throw (SPST) contact action. Typical applications include the sensing of low temperature conditions to avoid overcooling or icing of hydronic coils, cooling coils, and liquid handling pipes. The controls are compact and sturdy, and have an adjustable temperature setpoint range with a fixed differential. The range adjustment screw is accessible at the bottom of the control, and at the top of the control when the cover is removed

A19PRC type electromechanical temperature controls are designed for use in many agricultural applications. A19PRC controls have rugged Noryl® plastic enclosures and are UL Listed as NEMA Type 4X and for use in National Electrical Code (NEC) Article 547 Agricultural Environments (ANSI/NFPA 70). See Figure 1 and Technical Specifications. Adjustable A19PRC type temperature controls have O-Ring sealed external setpoint adjustment knobs and range scales with oversized markings for easy readability in low light. The exposed portion of the liquid expansion sensing elements has been tested per Article 547 of the NEC.
