In my project there is an absorption chiller supplied by district heating. The building itself is also heated by district heating. The two district heat quantities (one for heating, one for cooling) are metered separatly.
Would it be right to enter the two meter to Portfolio Manager? If both account for heating, that wouldn't make sense. has anyone of you a solution?
Thanks!

The energy usage should be based on whatever is coming from outside the property, so if there are two separate steam meters then both would be included, even if some of the steam is used for cooling equipment rather than heating.
If one of these was a submeter to the other, then only the main utility level meter would be included.
From your description of separate meters, both would be included in Portfolio Manager.
