[TRNSYS-users] problem with control signal of type 668

[David BRADLEY]

Eva,
  Quite a long time ago, there was a bug in Type668 that caused there to 
be a power output even when the device was off. However, this was fixed 
in 2005. You should contact your distributor and make sure that you have 
a more recent version. Also, Type668 has two control signals; one for 
heating and one for cooling. Make sure that both are switched to OFF.
Best,
  David
