Addendum t (Change the exception to 9.2.1.1)
Addendum u (Addendum adds dew-point and dry-bulb temperature as a shutoff control type in Tables 6.3.1.1.3.A and 6.3.1.1.3B and adds the required high-limit values for this type of control.)
Addendum x (Broadens the requirement for off-hour controls for HVAC systems. Revise Sections 6.1.3-i and 6.2.3.2 and add a new Section 6.2.3.3.5.)
Addendum y (Change Section 6.3.3.2.1 Part-Load Fan Power Limitation.)
Addendum z (Revise the Exception to 6.2.1)
