Allen commented bees will not fill supers or draw comb in supers unless they are warm.
What is the low and high temp in the super for bees to be working?
Is the upper ventilation used only to control temperature during hot days
so hive does not becomes to hot, or is it also to reduce humidity.

Some greenhouses have automatic temperature control
by opening and closing ventilation. Maybe the same principle
in miniature could work on a beehive.
