[EnergyPlus_Support] Unbalanced exhaust air flow warning

Hello Everyone,

I get the following warning:

    ** Warning ** In zone F006 there is unbalanced exhaust air flow.
    **   ~~~   **  During Warmup, Environment=SOFIA ANN HTG 99.6% CONDNS 
DB, at Simulation time=01/21 00:00 - 00:15
    **   ~~~   **   Unless there is balancing infiltration / ventilation 
air flow, this will result in
    **   ~~~   **   load due to induced outdoor air being neglected in 
the simulation.

There is an exhaust fan in zone F006 which I modeled using the 
Fan:Zoneexhaust. There is no infiltration or ventilation in the zone, so 
no outdoor air. To balance the exhaust air I use a ZoneMixing object 
which takes the necessary amount of air from another zone where fresh 
air is supplied by means of mechanical ventilation. The mechanical 
ventilation, exhaust fan and zonemixing use the same availability schedule.

Is there anything else that has to be done in order to get rid of this 
warning?

Thank you,
Miroslav
