The Johnson Controls A28AJ-25 is a two-stage temperature control system that is suitable for HVAC applications that require precise temperature control and when there are stricter control ranges. This long-lasting solution involves a remote sensor bulb which is attached to a control device through a 6-foot capillary line. The copper bulb which is credited for possessing a high heat transfer rate is placed in the area that needs temperature control. This model is unique as it has a fixed temperature difference of 3°F between the two levels. It works with power supply of 240V and essential for HVAC used in commercial freezers, cold storage and other areas that require strict temperature control.
