[TRNSYS-users] problems when simulate example

[David BRADLEY]

Ware,
  The example is intended to show you some ways of using Type42; it is 
not a very good example of a realistic device heating a tank. If you add 
the output of the controller to the online plot so that you can see the 
Type42 "heat pump" control signal you'll notice that the heat pump is on 
continuously through the length of the simulation; it does not have 
enough capacity to return the tank to its set point temperature. The 
fluctuations in tank temperature are the result of the varying water 
draw on the tank.
kind regards,
  David
