Controls using DC Analog Input/Outputs

(Standard Low Voltage Multi conductor
Wire)
Before installing any connecting wiring between the unit
and components utilizing a DC analog input\output signal,
refer to the Dimensions and Weights chapter for the
electrical access locations provided on the unit.
• Table 10, p. 47 lists the conductor sizing guidelines that
must be followed when interconnecting the DC binary
output devices and the system components utilizing a
DC analog input/output signal to the unit.
