DX Dehumidify. Similar to DX cooling, the output for dehumidification is determined by the difference between the setpoint and the average return humidity from each of the Modules in the System if more than one Module is present. The deadband is used to engage both compressors incrementally with increasing demand. Each Module in the System is assigned an equal division of the deadband a percentage of relative humidity. Both compressors in a Module are engaged when the assigned division of the deadband above the setpoint is reached. If the average return humidity reaches the setpoint plus the entire deadband, all of the compressors will be engaged until the humidity drops below the setpoint plus the deadband. Unlike DX cooling, the compressors in each Module are normally set to work as a single unit instead of separately. The use of one or two compressors per Module is based on the Dehum.
