I know that when cooling down a room it dehumidifies it , but what about heating ?

Humidification or dehumidification only occurs when moisture is either added or removed from the room or air. In cooling mode, moisture removal is seen as water (condensate) flowing off of the cooling coil. In order to remove moisture in this situation, the temperature of the air must be lowered to a point where the water in the air can't be suspended as a gas and therefor converts to liquid (called the saturation temperature). In heating mode, you are not acheiving the saturation temperature therefor you are not dehumidifying the air. Instead, you are allowing the air to hold more moisture - but not adding any. Therefore, you are reducing the relative humidity of the air.
(Relative humidity is the amount of moisture in the air as compared to how much the air can actually hold at different temperatures and moisture contents)

Cool Mode will make your room colder. The fan mode simply takes the current air form your room, filter's it, and blows it back out. Dehumidifying dries the air and takes the moisture out. Like a humidifier adds water molecules to the air and makes it sticky. For example, some days outside it's really hot and dry and others it's muggy and hot and sticky. The muggy/foggy hot air is very humid. Dehumidifying takes the stickiness out.

I believe heat causes a room to dehumidify more so than air conditioners.
I've noticed even when a room is heated by a fireplace the humidity drops in a room, I can tell this because it makes me feel ill like I'm drying out.

They are all correct about the heating of air decreasing the relative humidity. However, the airconditioner goes one step furthur. Whether the AC is in heating mode or cooling mode (assuming a car air conditioner) - you will still be running the actual airconditioner, which means you will be cooling the existing air (which will cause moisture to condense out) and then reheat it, which furthur reduces the humidity.

Assuming an air tight room, by raising the temperature, you are decreasing the relative humidity. As you make the air warmer, it has more capacity to hold water vapor. So in that way, you are dehumidifying the air not by taking any water vapor out but by increasing the capacity of the air to hold water vapor

No, not directly. When you heat the room, the ability of the warm air to hold moisture (which is the measurement of humidity) increases, so humidity will naturally decrease. But it does not actually remove humidity from the air in the same way as cooling does.

Depends if you have a humidifier on the unit.
