The damped outdoor temperature is
calculated from the current outdoor
temperature and a time constant which
takes into account the cooling
characteristics of an average building.
Note:
Remember to take account of the
plus/minus signs in front of the
temperatures.
The
average
outdoor temperature is the
criterion used for the heating curve. It is
calculated as follows:
