Dear Experts.
We get convergence problem in Type 56. According to our investigation source
of error is sudden increase of ventilation flow in our schedule and
ventilation air temperature about 3 K lower then room air temperature.
We would like to keep this control schedule and the same time avoid
convergence problem.
So far we have increase indoor air heat capacity in zones (five times), it
help a bit.
Do you have any other ideas what we could do?
Should we change something in Control Cards?
Best,
Karol
