unable to reach humidity setpoints

edit

I was doing analysis where my main motto was to limit the Humdity inside the room in any case 40-65. So Accordingly I had gone through all the example files and could set humidity limits that I want inside the zone.

I used the following options:

in sizing zone: for my zone set point 28 and 50% RH, the dew point (16.64) and corresponding Humidity ratio are used as supply air temperature and supply air humidity ratio.

1) Humidity set point 2) De Humidity set point

3) Humidistat

4) Humidifier (electric)

5) setpoint manager: single zone: humidity:Minimum (for this I kept the setpoint node at Humidifier outlet node and the placement of humidifier is just before cooling coil and used Humidification set point)

6) setpoint manager: single zone: humidity: Maximum (for this I kept the setpoint node at Cooling Coil outlet node and the placement and zone control node is respective zones nodes)

Please see the attached images

2)C:\fakepath\Humidistat.jpg

3)C:\fakepath\West Zone RH.jpg

Despite adding all the humidity controls (within my knowledge), humidity inside the zone is falling out of the range and can be seen from the figure. How to avoid this? Where Did I go wrong?

Any suggestions?
