Input/Output Summary

The following lists all possible bi- nary and analog inputs and out- puts available for the classroom unit ventilator applications. Some of the points listed may be mutual- ly exclusive and some are optional. (See Table 8: Input and output

summary)

Table 8: Input and output summary

Most binary inputs and outputs are wired from the factory based on unit configuration and options. If the generic inputs and outputs are to be used, wiring connections are made at the 1/4” quick-connect ter- minals provided.

Analog inputs from a wall-mount- ed zone sensor, humidity sensor, CO2 sensor, or a generic device

must be wired to the 1/4” quick- connect terminals provided. Most other analog inputs will be wired from the factory.
