[TRNSYS-users] Problems in using the Creating Equation

[h8304506@hkusua.hku.hk]

I want to generate a time dependent signal using the "Equa".  However, I get the
following error message:


* Equa:Tin ->Inlet fluid temperature [íu]                                       
                                                   

 ***** ERROR *****        TRNSYS ERROR #  98
 UNRECOGNIZED VARIABLE NAME OR BAD DATA CARD
 TIN                                                                            
                                                                              I
am using some intermediate valuables to generate Tin
(Tin=To+Ta*sin(360*time/period+phase)).  There is no input for the "Equa".  All
the intermediate valuables are set to some values in the "Equa".  Is there
anything wrong?  Please advise.  Thank you!
