In other words the system may or may not be ventilating or dehumidifying while the fan is running Common reasons for operating the fan continuously are continuous filtration and air recirculation With the fan in the off or program mode the fan will operate only when needed by other functions of the system The fan will remain off unless the system is dehumidifying and or ventilating The fan always runs during dehumidification it also always runs during ventilation To completely turn the system off use the ON OFF button as described earlier 5 2H Damper Operation and Setting Ventilation The damper setting controls the ventilation function of the system It has no control over the dehumidification function In order to provide ventilation the damper must be open on and the fan must be running The controller takes care of these two functions automatically so whenever the damper is open on the fan is running This is true even if the fan has been set to the off mode The ventilation indicator will be lit whenever the unit is ventilating There are three damper operation modes on off denoted by OF and program denoted by Pr With the damper in the on mode the damper will be open and the fan of the system will be operating in order to introduce fresh air into the space Use this mode for continuous fresh air ventilation The fan is always on when t
