Re: [TRNSYS-users] solar collector

[David Bradley <bradley@tess-inc.com>]

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
