Johnson Controls A28PA-2 2-STAGE TEMP. CONTROL NEMA 4X 2-STAGE TEMP. CONTROL NEMA 4X

2-STAGE TEMP. CONTROL NEMA 4X

The A28PA-2 2-STAGE TEMP. CONTROL NEMA 4X is a Johnson Controls brand and has been tested and validated by an independent, accredited testing laboratory in accordance with the International Electrotechnical Commission (IEC) standard IEC 62391.

Temperature Controller, A28PA-2 2-STAGE TEMP. CONTROL NEMA 4X, Single Stage controllers are designed for one heating or cooling source only. For use on HVAC systems that operate at very low voltages naturally or by applying low voltage power (24 VDC to 120 VAC). They feature a high-to-low power setting and a high/low temperature range switch.

The 2-Stage Temp. Control NEMA 4X is a 115V, PWM temperature control that can be used in temperatures between -22°F and 194°F (up to 95°C) for optimal temperature performance in controlled environments such as freezers and refrigerators.

The A28PA-2 2-Stage Temp Control NEMA4X is a powerful, compact starter/booster heater with solid-state microprocessor control for reliable, energy efficient heating operations. Operation is programmable based on simple input of set point temperatures and required outputs. Also features a built-in electronic controller over-temperature protection system and solid state relays, which means it is ideal for use in a wide range of applications

The Johnson Controls A28PA-2 2-Stage Temp Control Nema 4X is a low-voltage contactor (one coil, two terminals) capable of controlling moderate loads such as heaters and pumps. This contactor's output can be used in series with other contactors to control various loads in large heating and air conditioning systems.

The A28PA-2 is an explosion protected, two stage temperature control that provides digital control over gas fired circulators. The first stage operates at low temperatures for efficient heating and the second stage operates at high temperatures for effective condensing. This controller is NEMA 4X; consisting of an aluminum enclosure with stainless steel hardware. Maximum ambient temperature is 122 degrees F (50 degrees C).

A Series 2-Stage Temperature Control is a compact, NEMA 4X rated unit designed to provide independent temperature control in two separate spaces. It is ideal for laboratory, pharmaceutical, process manufacturing, commercial/retail and other applications that require precise temperature control.

The Johnson Controls A28PA-2 two-stage temperature control has both automatic and manual modes. It offers an easy installation, with no programming necessary. This nema 4x weatherproof control comes backed by a 2 year warranty

The Johnson Controls 2-Stage Temp. Control is designed for applications where it is desirable to control the temperature in both heating and cooling. It also offers the unique feature of selectable high/low setpoint for additional control capability, and can be used with packaged air-conditioners for true air conditioning capability.

The Johnson Controls A28PA-2 2-stage temp. control NEMA 4 is a type of thermostat, and is often used in the simple control of two-stage heating and cooling units. The device includes a 2-position switch and a pilot light for indicating proper operation.

The Johnson Controls A28PA-2 2-Stage Temp Control NEMA 4X provides protection against accumulation of ice on the evaporator coil. The low ambient sensor with manual reset cuts off power to the compressor if cooled air reaches 35 degrees F below the dewpoint chilled air temperature. This ensures ice does not build up on the evaporator coil and damage or destroy it.

NEMA 4X PREVENTS ELECTRICAL FAILURE, INSULATES AGAINST MOST POWER FACTOR CORRECTIONS, AND SHUTS DOWN A MOTOR IN THE EVENT OF A SHORT CIRCUIT. NEMA 4X STANDS FOR CORROSION RESISTANCE, LIKE ITS COATING OF ENAMEL-GRADE ALUMINUM ELECTROLYTIC FINISH.
