It is recommended that the evaporative cooler thermostat should be of a low voltage. High-voltage cooler thermostats result in greater temperature swings that are prevented if the evaporative cooler thermostat used is of a low voltage. Also, low-voltage thermostats are more accurate as compared to line-voltage thermostats. The use of an evaporative cooler thermostat is also recommended for the automatic opening and closing of the evaporative cooler. There are different varieties of evaporative control systems available in the market that contain a low voltage evaporative cooler thermostat and also a fan delay whose function is to turn the blower on only after the pads are wet.
Evaporative coolers are one of the most efficient means of saving energy, especially in areas where the humidity levels of the surrounding air are low. The efficiency of energy saving can be further enhanced with the use of a low-voltage evaporative cooler thermostat. Cooler thermostat control is highly recommended for an efficient saving of energy. It also prevents uncomfortable swings in the temperature and will help in maintaining the desired level of temperature that provides comfort. The evaporative cooler thermostat automatically cycles the evaporative cooler unit and maintains the optimum level of temperature. This prevents an unnecessary dissipation of energy caused due to wasteful running of the evaporative cooler.
