Figure 4-1: Communications Loop Overview
Each Zone Manager (HVAC unit) has a separate Local communications loop for
associated Zone Controllers and any Constant Volume units used.
Each Local loop must have a unique cluster address. It is typical for each Local loop to
have a sequential cluster address (e.g. 1, 2, 3, etc.).
Note: No controllers should be connected to the Network communications loop.
