Description
The Johnson Controls A19ACA-34 Remote Bulb Temperature Control is a reliable device that helps to control specific temperatures in HVAC systems. The control unit has a fixed, non-variable differential, thus the temperature difference between activation and deactivation is fixed. The control device reacts when the temperature goes higher or lower than the set range of temperature. For instance, the heating apparatus will only commence when the temperature drops below 35°F and stop when it rises to 40°F. A single-pole double-throw switch allows the control to switch heating or cooling equipment depending on the temperature change.
