Description
Johnson Controls A19AAC-4C Bulb Temperature Controller, a multifunctional appliance mainly applied in HVAC systems to maintain temperature with high accuracy. It uses a sensing element that is filled with liquid and whose volume changes with temperature. This expansion or contraction activates the control output, which is SPDT, and enables it to turn heating or cooling equipment on or off. This controller is intended to control temperatures within a certain range of 0°F to 80°F with a differential of 5°F. It has a high voltage range capacity of 120VAC – 240VAC so that it is fit in different electrical networks. The sensing element is 6 feet long so that it can easily be placed in any position as required.
