Hi,
        
 this is my way in order to enrich the moisture.
         
        
 In the first position (MEMJET), we apply a fixed resistance of 6 Kohm.
         
        
 In the second position (MEMJET + NTC), we apply to normal NTC air temperature sensor, a fixed resistance of 1.5 Kohm.
         
        
 Of course the value of resistance is settable. I call it "fixed" because, after many test, are the best values. By.
