Description
Johnson Controls A11B-1C Auto Reset Control Low Limit SPST, component that is used to safeguard HVAC systems from freezing conditions. This device works through sensing temperature, particularly in a range of 3-7°C and initiating actions to protect equipment when the temperature is low. The control output is a single-pole single-throw (SPST) that can handle a broad voltage of 120 VAC to 240 VAC. This is mainly used in heating, ventilation and cooling systems; it is applied especially in refrigeration systems, heat pump, and other air conditioning systems where precise working conditions must be met.
