Dear TRNSYS users,

I found that non-standard component Type540 (solar collector with
capacitance) predicts collector temperatures lower than ambient
temperatures at no-flow conditions. As the component does not consider the
LW exchange with the sky, this result is impossible. I think that the
problem comes from using TIN=XIN(1) as the temperature of the first node
(TBAR(1)=TIN) when the fluid is not in movement.
