Two main goals (with some intersections)

1. HVAC revision with focus on:

       1.1 radiator #205
   
       1.2 pump #184 and #268
   
       1.3 (thermostatic) Valve #182
   
       1.4 solar collector #293
   
       1.5 heat exchanger #274
   
       1.6 geothermal field, open issue for it
   
       1.7 hydraulic resistance, open issue for it
   
       1.8 hydraulic separator, open issue for it
   
       1.9 pipes, open issue for it 
   
       1.10 active walls, open issue for it

For all new opened issues, check Annex 60 for similar models.

2. Annex 60 integration

       2.1 Weather model #181
   
       2.2 valves (see 1.3) 
   
       2.3 pump (see 1.2)
