Here, you select how long the installation will work with each
demand, if there are several simultaneous demands.
If there is only one demand, the installation works with that
demand.
If 0 minutes are selected, this means that the demand is not
prioritised, but will instead only be activated when there is
no other demand.

VVM S320 will wait before it returns to heating mode when
the cooling demand has ceased or vice versa.
