?energy input by fluid of active layer to zone?

[Tomas Persson <tpe@xxxxx>]

Hi!
I have used the built in active layers of type 56 to model floor heating
(slab on grade). I have a problem with the output nr 59 (QALFL energy
input by fluid of active layer to zone) it gives negative values, much
larger than the power going into the floor calculated externaly from
input flow rate, input temperature, and output fluid
temperature from output 58 (TOFL fluid outlet temperature of active
layer)

What is output 59 supposed to calculate?
What can be wrong?

I use quite old versions of Prebid and Trnsys 15 (from 2000), due to the
fact that I started this project using these versions, and the fact that
I use Presim and that Presim is not updated for the latest
Prebid-version

Best regards Tomas Persson
