: Advanced Installation and Configuration Instructions
Installation Settings > Equipment > Humidifier > DeHum for Fan Coil or Furnace
When this feature is wired and set up along with AC Overcool Max, it allows multiple modes of cooling operation, including temperature only
demand, dehumidification demand, and both. When the DH or DHUM terminal on the equipment is energized, it will slow down the variable speed
blower to increase latent capacity of the evaporator coil, while reducing sensible capacity.
Installation Settings > Thresholds > Cool Dissipation
Cool Dissipation Time is default on, but the feature should only be used in very dry climates, such as Phoenix or Las Vegas. For the rest of the country,
the fan should not to run at all after the cooling cycle is over. Setting the Cool Dissipation Time from Auto to 0 will allow the moisture on the
evaporator coil to run down into the drain pain and leave the system. If the fan were to continue running, much of that moisture would re-evaporate
back into the home.
The graph on the right illustrates humidity going back into the home after a cooling cycle as the fan blows air across a wet evaporator.
