(Optional) Calibrating with an Autozero Module
This section is for fume hoods with an external pressure sensor and an Autozero
module. If the DP Transmitter is slightly out of adjustment, you can compensate for that
within the controller.
1. Set REPORT to AIRFLOW IN.
2. Set CAL AIR to YES.
When calibration is completed, this point will automatically change back to NO.
AVS FAILMODE
AVS FAILMODE is a point that describes how the Venturi Air Valve will respond if the
Air Velocity Sensor (AVS1) fails.
Set AVS FAILMODE to the desired value.
AVS1 failure and AVS FAILMODE values.

1.
Set REPORT to

2.
Do one of the following:
– For a single Fume Hood wired to an LRC:
Set AO2 RANGE to the maximum expected flow for the fume hood, plus
approximately 10%. For example, if the maximum flow is 900, set it to
1000.
– For two to six Fume Hoods wired to an LRC using a Fume Hood
Averaging Module:
Set AO2 RANGE to the maximum expected flow for the largest fume
hood, plus approximately 10%.
The AO2 RANGE point must be set to the same value for all fume hoods
connected to the Fume Hood Averaging Module.
⇨ AO2 is now active and a proportional 1 to 10V signal can be read on
AO2.
3.
Set AO2 DEADBAND to the desired value.
