It provides a yearly time clock program with 15 daily routines (800 switching events), a weekly schedule and allowance for 100 special days. Additionally, the unit can control up to 300 participants in 30 macro groups, that can be triggered using a single command. In this way each time controlled switching event can cause a series of actions. The switching times can be modified with the free PZM 2.0 software without using ETS.
