Johnson Controls A70KA-1 Low and High Temperature Limit Controls M/R Open-High 6" Capillary Control 100/170°F

The Johnson Controls A70KA-1 is a High-limit safety control suitable for use in HVAC systems. It also has the ability to turn off the system if the temperatures go high, which is a range of 100°F to 170°F in this case. This is a single-stage control where the sensing element is vapor charged and is used to detect temperature variation or switch when the limit is attained. It is a manually reset control which implies that the control will have to be switched on after a shutdown. It has a long lasting construction with rolled steel frame and aluminum flange for the frame. The 6” capillary tube is used in placing the sensor at any desirable place in the HVAC unit to accurately measure temperature.
