Dear Eva,
Type505 is a water source heat pump (also known as water-to-air heat pump), and Type668 is a water-to-water heat pump. Both of these components have been archived for the newer and more user friendly, normalized versions, Type919 and Type927. I would highly recommend upgrading this TESS HVAC Library to version 17.1. it is only about $60 to upgrade that library from your TRNSYS Distributor when you upgrade to TRNSYS 17. To answer your other question about the data files, this component and many other HVAC components implement the 'InterpolateData' routine ( 'DynamicData' in TRNSYS16). Please see the Programmer's Guide for information about formatting.
Best regards,
Matt Duffy

Dear Sirs,
I try to model ground source heat pump system. I use type 505 but it is not clear for me (I read the documentation too) the difference between this type and the type 668. If anyone can make some clarifications it will be very helpful for me.Thank you.Regards,Eva
