R. All zones served by a SlimZone control module should have the same basic load characteristics
(i.e., do not put 4 zones on an east exposure, and the 5th zone on a southwest exposure).
S. All references to typical dampers refer to Enerstat model dampers.
T. Zones 14-19 adhere to the same schedule and act as a single call for equipment. Although they
are separate physical zones they act as a single zone when communicating with the SZP
Control module. It is recommended that when considering the layout of your zone system,
zones 14-19 should be assigned to areas of low priority.
