[TRNSYS-users] solar collector

[David Bradley]

Fillipo,
   Your collector pump is on whenever it is both 
a weekday and daytime regardless of whether the 
temperature of the collector outlet is hotter 
than the temperature of the tank (the output of 
Type2b isn't used in your CntrSignal equation block.)
Cheers,
  David
