2-2.3.1 VAVMax Dierential Pressure Input
The Dierential Pressure Input is only available on the VAVMax (VM01) controllers. It is used to
measure and respond to changes in air velocity pressure, which is determined by how the VAVMax
controller has been configured. The pressure sensor is factory calibrated for optimum performance
and is an extremely sensitive electromechanical device. Therefore the following guidelines should be
observed to prevent irreparable damage to the pressure sensor:
Do NOT apply pressure from sources other than a pitot tube
Do NOT apply excessive static or dierential pressure when connecting or disconnecting air supply
hoses to the VAVMax controller
Do NOT drop the VAVMax controller
Listed below are the general operational parameters for the Dierential Pressure Input:
3000 Pa maximum static operating pressure
0 to +250 Pa dierential operating pressure
-10 to +300 Pa maximum rated dierential pressure
Accuracy rate of ±5FS
Only non-corrosive gases are to be used
