Up to 45 actuators can be controlled and operated with the hand control unit.
Up to 21 devices can be added to each group.
Devices can also be contained in several groups, for example, a group for the first floor can be created in which 8 devices are, another group for the upper floor in which again 8 devices are and a third group in which all devices are contained. In this way, different times can be set for the individual floors, but the third group can still be used to operate all the devices together.
