ALC

In the context of thermostats, the abbreviation "ALC" stands for Automatic Limit Cooling. ALC is a function or mode present on some thermostats that provides indoor cooling or air conditioning control. This function allows the user to set the maximum temperature at which cooling starts to maintain a comfortable temperature in the room.

When the room temperature rises above the set value, the thermostat automatically starts the cooling system (such as air conditioning) and starts cooling the air to keep the temperature below the set limit. In this way, the ALC function helps to maintain a consistent and pleasant temperature in the interior, thus ensuring comfort and efficient use of the cooling system.

The abbreviation "ALC" can have different meanings depending on the manufacturer and model of the thermostat, but it generally refers to the cooling control function based on the automatic setting of the temperature limit.
