This page is dedicated specifically to finding an average outlet.
After an average outlet is found, that outlet can be set to each
specific ideal velocity that was calculated for all speeds/modes
on previous pages.
Finding the Average Outlet
1. Ensure all zone dampers & outlets are fully open.
2. Jumper or set thermostat to cooling speed.
3. Energize Fan Coil.
4. Using the following chart, fill in outlet location and outlet
velocities. HE outlets should go in the HE column (A) and 2”
outlets in the 2” column (B).
5. When all outlet velocities are recorded, pick a column (A or
B) with the most outlets.
6. Total all velocities in the selected column.
7. Then divided by the number of outlets in the selected col-
umn. This equals the average velocity
of the selected column.
_______FPM or knots ÷ ___ Number of outlets
= _______FPM or knots Average Velocity
8. Now that the average velocity of the selected outlet type
has been determined, from the column chosen select one out
-
let that is closest to the average velocity.
9. The average outlet is outlet #____
10. Now that the average outlet has been found, set this outlet
to the determined “velocity per outlet” that was calculated in
the preliminary system information section above.
11. This will have to be done for all speeds/modes.
