The connection has preprogramed features for the following inputs: Common wire Connection for positive pressure mode. This may be a toggle switch connected. The supply airflow into the home increases by 25% from its existing setting with the exhaust airflow remaining constant. This setting continues for the entire duration the contact is switched on. When turned off, the unit will return to its previous airflow setting. Connections for CO2 sensors, air-quality sensors, humidity sensors etc. These contacts will initiate the unit s maximum CFM setting to increase air exchange. After disconnection, the unit will return to its prior airflow setting. Connections for momentary contact booster switches, which are typically located in bathrooms and kitchens. Press the booster switch for less than 3 seconds to initiate the unit s maximum CFM setting for a 20 minute duration. Press and hold the booster switch for more than 3 seconds to initiate the unit s maximum CFM setting for a 2 hour duration. After the set amount of time, the unit will return to its prior airflow setting. At anytime during a boost period, pressing the booster switch again will return the unit to its prior airflow setting.
