[Equest-users] stumped re. excessive heating

[Chris Jones]

I used Botota for the weather file.  For system 
UMA 102, I changd the cool control to Warmest and 
Heat Control to coldest and changed the reset 
priority to Temperature First.  The heating 
energy is cut in half.  Do that on all the 
systems and you man chop all the heating in half.

The danger of self-sizing with program default is 
you don't know what or why the results don't appear correct.
