The MD6-ES24VK outside air kit combines the MD6 with the ES24V to allow fresh, clean air to enter the building. The ES24V can command the central HVAC blower to help distribute fresh air through the existing duct work if necessary. It can be programmed to allow outside air to enter intermittently when the temperature is inside of your set temperature and humidity parameters. This prevents hot, humid or freezing air from flooding your house all at once, while still meeting code.
