I'm trying to use heat recovery, sensible when using IdealLoadsAirSystem, but it doesn't work. Does anyone know what can be wrong?

In the fields for the ZoneHVAC:IdealLoadsAirSystem object, you need to specify both a sensible heat recovery effectiveness and a design specification outdoor air object name so that you have outdoor air exchange for the heat recovery to act on.

If you are doing this in OpenStudio, there is a measure posted in this question on the forum to edit these objects in your model.

Thank you very much for your answer! I have done both now, but it's still not working...

can you be more specific about what isn't working? Have you tried including output variables for your ideal loads system objects to see the energy flows?
