HVAC MONITORING
This application uses two pressure sensors (two SmartBug modules) to report the differential pressure output
on HVAC filter systems or for any filter clogging application.
1.
Make sure the slave device is configured and connected.
2.
Select the
HVAC Monitoring
window and click on the
Enabled
checkbox to enable HVAC.
3.
Place the two modules (with a pressure sensor each) on two sides of any air filter.
4.
Click the
Calibrate now
button to calibrate the master and slave pressure sensors to the same level.
Two pressure sensors can show different pressure sensor readings, even when placed on the same
altitude. The calibrate button ensures that the master and slave pressure have an initial differential
pressure value close to zero Pascals. This ensures accurate differential pressure monitoring for HVAC filter
monitoring type applications.
