[TRNSYS-users] Using operators within the Equation Component

Javier,
   There are a number of operator arguments available. Please check the 
TRNEdit manual for a full description (section 7.3.9 if you are using 
TRNSYS16, section 6.3.9 if you are using v17). What I would recommend 
you do is to use the GT() and LT() functions to set a multiplier that 
has a value of 1 or 0. This multiplier can then be used in an equation 
that sets both Q_aux and Q_need.
Best,
  David
