[TRNSYS-users] Type 60c outlet temperature

[David BRADLEY]

Barto,
   It is not really possible to diagnose the problem without looking at 
the project. I would recommend using an online plotter to look at all of 
the temperatures and flow rates of all the flows going into and coming 
out of the tank. If for some reason all of the temperatures in the 
system are over 60C (including the temperature of the tempering water) 
then Type953 would not be able to temper the outlet flow. It could also 
be that you are seeing higher than 60C temperature at the mixing valve 
when there is no flow through the valve.
   If you are not able to sort out the problem using Type65 as a 
debugging tool then you should send your project to your distributor so 
that they can have a look at it.
Kind regards,
  David
