3.2 Livezi Connect variable airflow multizone controller
The Livezi Connect control system is a variable air volume (VAV) system with a 24 volt AC
supply.
The Livezi Connect control modules (3) monitor the temperature for each zone from the
sensor mounted in each zone touchpad (5). The zone dampers (4) open and close depending
on whether or not the air being supplied by the HVAC plant (1) & (2) will assist the zone in
maintaining the set temperature.
