When a UIO on a VAVMax or a MicroMAX controller is configured as a Thermistor input type, it is

designed to be used with Innotech SEN Series Detectors. The sensing range and accuracy for the SEN

Series Detectors is as follows:

• Nominal sensing range: -5°C to 60°C

• Accuracy ±3.5%FS (R25°C = 10kΩ)

3-3.3.2 Universal Inputs / Outputs

The VAVMax and MicroMAX controllers are equipped with two Universal Inputs/Outputs which can

be configured with MAXCon software to be used as inputs or outputs. Each Universal Input/Output

has a signal terminal (+) and a reference terminal (–). The types of inputs and outputs that can be

configured and the respective range for each is shown are Table 3-11 below.

It is not recommended to use the Pulse Counter on these controllers for accumulation as these controllers are not

equipped with battery backup or flash RAM. The MAXIM II, MAXIM III, and MAXIM 1010 controllers are better suited

for such situations.
