N-S5 Test
The ‘TEST’ function allows structured testing of the VAV- / CAV-box to be
carried out.
When the function is started it first checks the system supply pressure
and then runs to a defined typical value of volumetric flow with the help of
a preselected Test-Sequence. The Trend window is opened so that the
test results can be checked and stored.
For the purpose of carrying out reviews, the Test-Sequence recorded
from the installation can be read from the hard disk, displayed on the
screen and printed out.
