You will need a zone controller if you want to turn a single zone HVAC system into a multiple zone system. The zone controller will connect to the HVAC system and control it. The HVAC system sees the zone controller as just one thermostat so it just does what it is told. The Zone controller's job is to take the request from all the connected thermostats and serialize and package the requests to the HVAC system.
