It depends on personal preferance,an air conditionner is going to remove humidity or water from the home,as water contains heat.

I would shut off the humidifier.The 40% setting depends on where in the world your located,say nevada is dry and hot so you may want a humidifier.Where florida is hot and humid so you would want to dehumidify or get rid of the humidity.

Lower the setting to 20% or just turn it off.

My Aprilaire 600 is dripping

Hello, check to make sure that the drain line is not blocked, this could cause the water to back up in the humidifier and leak, also make sure the water panel is clean and free of any mineral deposits.

Keep running

You should have a #50 relay hooked up to the main blower assembley to turn the 24 volts on and off with the blower to the humidistat. Alot of humidifiers sold do not tell you about the #50 relay. They assume that you are a hvac pro and you aready know about.
Good luck
