Johnson Controls A19ABC-12 SPDT Temperature Control With Well Thermostat 100°F/240°F 8"

The Johnson Controls A19ABC-12 SPDT Temperature Control with Well Thermostat is a small switch that is efficient in maintaining temperature in the HVAC system. It uses an 8” capillary bulb that is used to measure temperature and turn on a switch depending on your desired settings. The control has an auto change-over differential, which makes it possible to turn your heating or cooling system on or off when the temperature changes by a certain amount from the set point. This helps to avoid short cycling which in turn reduces the amount of stress on your HVAC system and possibly lower electricity bills
