DESCRIPTION:The resource theory of quantum thermodynamics has been a very 
 successful theory and has  generated much follow up work in the community.
  It requires energy preserving unitary operations  to be implemented over 
 a system\, bath\, and catalyst as part of its paradigm. So far\, such unit
 ary  operations have been considered a &ldquo\;free&rdquo\; resource of th
 e theory. However\, this is only an idealisation  of a necessarily inexact
  process. Here\, we include an additional auxiliary control system which c
 an  autonomously implement the unitary by turning &ldquo\;on/off&rdquo\; a
 n interaction. However\, the control  system will inevitable be degraded b
 y the back-action caused by the implementation of the unitary\,  which can
 not be perfectly implemented. We derive limitations on the quality of the 
 control devise so  that the laws of thermodynamics do not change\; and pro
 ve that the laws of quantum mechanics allow  for a sufficiently small back
 -reaction so that the implementation of thermodynamic resource theoretic  
 operations can be achieved without changing the paradigm\, in addition to 
 finding limitations for  others.  <br><br><br><br>
