[TRNSYS-users] error type 665 with high heat power of performance data

  Type665 just reads performance data from an external file. There is no 
restriction on the size of the heat pump that can be modeled. If you 
have the data file for the mitsubishi PEADRP125JA entered correctly then 
Type665 will read it. If that model of heat pump has a variable speed 
compressor in it then Type665 is not an appropriate model to use. 
Type665 models an on/off device whose compressor speed is not able to 
modulate and would possibly therefore use more power under low load/duty 
cycle conditions.

kind regards,
