Free Indoor Digital Hygrothermometer included with each 1770 Dehumidifier The new Model 1770 replaces the model 1720 dehumidifier. It features: * Updated housing color * New LED status and service indicator tells you when the unit is running normally, sampling, defrosting and when it is in need of service Excess humidity in the air can cause homes to be smelly, musty and noticeably damp. Nobody wants to go there, play there, be there. Excess humidity can damage basement furniture and furnishings, cause wood to swell and fabric to rot. Stored items grow mildew and wall paneling peels. High basement humidity can lead to health threatening conditions too. Any basement with relative humidity regularly above 60% can become the perfect breeding ground for a variety of pathogens like mold, mildew and fungi. Common portable dehumidifiers are a weak answer - they don't perform well in cooler basement environments and you typically need more than one to treat your entire home. The solution - This Aprilaire Central Dehumidifier is designed specifically to control humidity inside the whole home as well as in crawlspaces and attics. Built-in duct collars alow for easy connection to the central HVAC system. This dehumidifier automatically and continually measures the true measure of moisture level, dew point. The unit operates to control humidity to the dryness set point that is either set on the unit or on the optional living space control. A built-in, automatic air cycling feature can be utilized to activate the HVAC fan to cycle the air throughout the whole home for proper balance for comfort. This dehumidifier also has a patented, built-in ventilation feature, which will allow fresh air to be brought into the home from the outside. In utilizing this feature, the dehumidifier will dehumidify the incoming air, if needed (based on dew point / dryness set point), as the outside air is first entering the home. The built-in ventilation feature is designed to be able to meet ASHRAE 62.2 Standard for Ventilation. The Aprilaire Model 1770 Whole-House Dehumidifier works throughout your entire home.
