Zone Manager Wiring
Correct wiring of the Zone Manager is critical to proper system operation. If components
are wired to the wrong inputs, the system will not operate correctly or will not operate at
all. Correct wiring of the 24VAC power is extremely critical. If voltage greater than
24VAC is applied to the terminal, it will damage the board beyond repair. All 24VAC
wiring must be connected so that all ground wires remain common. Failure to comply
with this will also result in damage to the board. See Figure 4-7. Also see Section 2 of
this manual for more detailed wiring instructions and procedures.
