[TRNSYS-users] Controller Type2b seems to generate error in flat plate collector outlet temperature

[Hooman Azad]

Dear friends

Please check my simple circuit. A 150 kg tank is supposed to be maintained
at 60 degrees all year. A flat plate collector has been employed. When you
run the simulation (file FPC1), you see some sharp rises of collector outlet
temperature, as high as 400 degrees, which are obviously wrong. 

If you remove the type2b controller and, for example, control the pump with
type14h (file FPC2), the sharp rises disappear. It seems type2b is
responsible for the errors in the first case. Thank you very much for your
kind help.
