The P70 Controls for low pressure applications are designed primarily for low pressure cut-out control, pump-down control, and capacity control on commercial refrigeration and air conditioning applications. These controls are available in several pressure ranges and are compatible with most common refrigerants. They may also be used on other non-corrosive fluid applications. Ammonia-compatible models are also available.

• All-steel case and cover built to provide long lasting, rugged protection for internal components
• Sight-set calibrated pressure adjustment - displays a visible pressure scale, fully adjustable through the range without removing the cover
• NEMA 1 enclosure, no adjustment knob
• Ammonia compatible

Johnson Controls A19DAC-1 Gray Baked Enamel Cold Rolled Steel Hot Water Johnson Controls A19 series temperature controls are designed to cover a broad range of uses for heating and general purpose requirements. Controls have SPST contacts which open on temperature increase or they may be supplied in SPDT contact action. Various control ranges are available to cover working temperatures from -30 to 550 deg F. Closed tank fittings and bulb wells are available for immersion applications. These controls are designed for open low and open high applications. Where critical or high value products are to be maintained within a specific temperature differential, a 1-control should not be applied to function as both an open low and open high control. In these applications, a separate backup control with alarm contacts should be wired to indicate when the back-up control operates.,

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
