CAV installation and wiring.
Note:
For optimal measuring results, measuring points with turbulent air flow should be avoided. Preferably,
measuring should be performed at a distance of 2 duct diameters before bends and branching and at 6 duct
diameters after bends and branching.
Supply air duct
1. Install IRIS damper or similar device with known K-factor into the supply air duct.
2. Connect tube from the IRIS damper or similar device to +.
3. Connect the tube from supply air duct after IRIS damper to -.
Extract air duct
1. Install IRIS damper or similar device with known K-factor into the extract air duct.
