Description
The Johnson Controls A40EA-4 Pneumatic Temperature Control is a durable device that is helpful for controlling the temperature of HVAC equipment. It is a bulb and capillary type that operates through the change of heating or airflow depending on the set criteria of the surrounding temperature. The temperature range of the product is between 50°F and 90°F and the product automatically resets the temperature by switching the heater and cooler on as required. The accuracy is enhanced by the fixed 4°F differential, which reduces energy wastage through rapid cycling. Due to its NEMA 1 enclosure which protects internal components and also guarantees durability in various environments, this product is suitable for commercial and industrial uses in HVAC systems.
