System Selection
Orion Controllers can be connected together with communication
wiring and devices to form complete systems solutions. Orion Con-
trollers can be confi gured into four main system types. The right
system for you depends on the number and type of controllers being
used. Each of these main system types have a series of options avail-
able that relate to what kind of operator interface(s) you wish to use
to program and monitor your Orion system. Several other options
are available depending on the system type and operator interface
you have selected. By selecting the right system and options, you
can build a complete HVAC controls system that will meet your
job requirements.
Using the Selection Chart
WattMaster has designed this publication in order to make it easy
to select the right Orion system type for your specifi c application.
Start by selecting a main system type from the selection chart below.
Proceed to the pages listed on the selection chart for information and
available options for that system type. After deciding what operator
interface and other options you want, proceed to the connections &
wiring section pages listed for that system type for detailed instal-
lation information.
