Hüseyin,
If you are allowing the temperature of the space to float then there
are no energy demands on the space. If you set a heating and/or cooling
set point temperature such that the temperature of the space is limited
and will not fall below the heating set point or rise above the cooling
set point then you will start to see energy demands: the energy required
to maintain the space between the bounds that you have defined.
kind regards,
David
