Heat Recovery Actuator

@MingboPeng

Having some trouble with the Heat Recovery… it is not recovering any energy.

Looking at the .idf file, it appears that it is specifying the wrong node as the actuator in the Outdoor Air Controller… I think it should be Node 176 not 173.

If I specify this node and rerun the .idf, the energy improves (although admittedly the On-site Thermal Sources output still says 0 for Air to Air heat recovery, which is puzzling to me).

Have I stumbled onto a bug in how the actuator is specified or have I configured my heat recovery set up incorrectly somehow?

@MingboPeng Wondering if there was any thoughts on this. Seem to frequently have issues with HR in ironbug. Not sue if this particular theory is a red herring or if there is something else off in my HR configuration.

May have answered my own question. I had the DesignReturnAirFlowFractionofSupplyAirFlow set to 0, once I disconnected it the HR worked.
