Specicaons
EZvav specicaons are subject to change without noce.
Inputsandoutputs
All inputs and outputs are factory programmed and applicaon specic. No eld conguraon is required. For details on input and
output connecons, see the topic Applicaon drawings on page 29. For a detailed lisng of input and output objects, see the topic
BACnet objects on 44.
Analoginputs
Analog inputs represent BACnet analog input. Not all input are applicable or required for all models.
