Hei Mirjam,
Latin and botany - a sure way to lure me.
First of all: Congrats to your new plant! I don't really have experience with Cycas revoluta, but my parents have a Cycas plant. It stands in the living room in a rather shady place at 18-25°C, in the summer even warmer. My mom waters it, and only the most robust and easy-care plants survive her gardening skills.
I did a quick web-research for you, and
this site seems rather sound and helpful. The gist is: Your new roommate likes direct sun or at least a bright place and regular water. It gets better along with some dryness than with too much water; but avoid dryness when new leaves are developing. Some mild fertilizer is appreciated in spring and summer. It tolerates a wide range of temperatures, so normal room temperatures should not be a problem. You ought to avoid cold draughts, though.
General rules that hold for all plants are: Too much fertilizer is harmful, and the warmer a plant stands, the more light it needs. Never ever water them by a fixed schedule ("every Monday and Thursday") but always by their need - water them, when the surface of the soil has become dry.
If you have any more questions, don't hesitate!
Cheers!
