I assume the Standard must be followed when the User’s Manual contradicts it.

90.1 – 2010, Standard

9.4.1.3 (b)           “….reduce lighting power of each luminaire by a minimum of 30% when there is no activity for no more than 30 minutes.”

90.1 – 2010, User’s Manual

9.4.1.3 (b)           “….reduce lighting power to 70% or less of maximum when there is no activity for 30 minutes or longer.”

The Standard requires auto-control to reduce light power at 30 minutes or before.

The User’s Manual requires auto-control to reduce light power after 30 minutes.
