Starzone 4000 Master Control Panel

Figure 2.1 Master Control Panel

The heart of the Starzone 4000 system is the Starzone Master controller

(SZM-4000). Each AHU that is to be zoned will have its own SZM-4000

Master control panel and each panel can operate independently or be

networked together via a 3-wire, RS485 communication bus back to a

central PC.

To make servicing the SZM-4000 Master easier, the controller has two

parts: a motherboard, which has all the connectors for field wiring, and an

electronic daughter board which plugs into the motherboard.
