Installation Guide

Note: If the ΔT becomes less than the Min Delta Temp, the AFMScontroller will abort Learning Mode.
This is to insure that the controller does not receive unusable learning samples. 10°F or more Min Delta
Temp is recommended.
2.
Leave Auto Start Delta Temp set to the default, or adjust it if needed.
Note: When the ΔT reaches the Auto Start Delta Temp, Learning Mode will start. Learning Mode will
complete if the ΔT remains greater than the Min Delta Temp for the entire duration. An Auto Start Delta
Temp that is at least 10°F more than Min Delta Temp is recommended.
3.
Leave Time Between Samples (Seconds) set to the default, or adjust it if needed.
Note: Most often, Time Between Samples (Seconds) can be left on the default (60 seconds). You might
increase the value if the damper Stroke Time (Seconds) (found under Configure > Damper) is longer than
that of a typical unit, or if the damper actuator requires extra time to respond.
4.
For Auto Learn Enable, select ON.
5.
Select Save.
Note: See the Date of Last Learn and the OAT When Learned once Learning Mode has run automatically.
Alternative to Running Learning Mode
While not ideal, the damper characterization data can be calculated and entered manually. This should only be done
if — in the allotted time for setting up the AFMS — the ΔT is unlikely to remain greater than the Min Delta Temp for
the duration of Learning Mode. See Manually Entering Damper Characterization Data on page 14 for
guidance.
