Description
The Johnson Controls A19AAD-5 Remote Bulb Temperature Control is a effective and easy-to-use device that can help control the temperature in different applications. It employs a remote sensor bulb that is connected through a 6-foot capillary tube to a control unit. The sensor bulb is filled with a liquid that increases or decreases in volume with temperature change. This expansion or contraction is carried by the capillary tube to the control unit that switches either your heating or cooling equipment depending on the setpoint to maintain the temperature range within the given 30° F – 50° F.
