A cooling thermostat line voltage is a type of thermostat that is used to regulate the temperature of a space. It works by measuring the temperature of the air and then activating a cooling system when the temperature rises above a certain threshold. The cooling system then brings the temperature back down to the desired level. This type of thermostat is often used in commercial and industrial settings, as it is reliable and can be easily adjusted to meet the specific needs of the space. It is also an energy-efficient way to keep a space at a comfortable temperature, as it only runs when necessary. The thermostat line voltage is an important part of any cooling system, as it helps to ensure that the temperature is kept at the desired level.
