Johnson Controls A19ABC-2 SPST Temperature Controller Adjustable Differential 20°F-80°F 6' Capillary 3.5"-14"

The Johnson Controls A19ABC-2 is a Flexible Temperature control switch that enables the adjustment of temperature in HVAC systems. This device has both surface and panel mountings making it easy to install in any location. An essentialfeature is the variable differential range of 3.5°F to 14°F. This allows the users to choose the range of temperature variation before the switch is thrown. For instance, if the switch is set 5 ° above the target temperature at 70 °, the cooling equipment will be engaged once the temperature starts to rise to 75 ° and the other way around, the cooling equipment will be turned off if the temperature is below 70 °.
