What exactly is the problem statement of this homework assignment?

Where are you located?

Is there any reason you can't do something as simple as:

if temperature is low
  then heater on
  else heater off
repeat

So put it on a server and post a link.  Before you ask 2000 people to look
at your work, make sure it is presentable and in a reasonable format.  Make
sure every part in the schematic has a designator so we can talk about it
easily.  Make sure labels are readable and not overlapping other things,
etc.  Use a reasonable file format.  Many people won't be able to read your
schematic if it is in the proprietary format of your EE CAD tool.  Exportin=
g
it to PDF would be a good idea.  Remember that JPEG isn't good for line art=
..
Don't just take a screen snapshot.  Do it right.

When someone asks questions, answer ALL of them as asked, whether you think
they are relevant or you understand their purpose or not.
