openstudio dehumidifying with humidistat shows no effect

Hello everyone! I am trying to make an HVAC system that keeps a relative humidity at 60%. The building is in a very humid climate therefore I need dehumidifying. I tried to proceed as described in link However when I simulate it, the humidity is still at 90-100%

I proceeded like this:

  1. I created a scedule set to a constant value 60, with 'scedule type' set to 'percent'
  2. I created a 'Setpoint Manager Single Zone Humidity Maximum' at the outlet node of the cooling coil
  3. I set the control variable in the cooling coil to 'Temperature and Humidity Ratio'

What am I doing wrong?
