Hi Fred

I don't know if it works well without a cooling map, but if you need to use
the heating mode only, you can use the default cooling file in the
"SampleCatalogData" folder to fill in the gap.

Subject: [TRNSYS-users] Type 668 Heat Pump Performance Issues

TRNSYS Users, 

I am using a type669 heat pump in heating mode only and I have entered a
performance map for the heating side. 

If I am using type668 in a heating mode only way, do I need to input a
corresponding cooling map?

In other words, are both a heating and a cooling map required for proper
operation of a heat pump in heating only mode?

What I am seeing in my output is that the heat pump heats the load side, but
does not draw any heat from the source side. 

Please advise,

Fred
