Main Control Method
The Main Control Method Window (Figure 35 below) is located
on the left of the Relay Confi guration Screen (Figure 34, page 21).
Figures 36 through 43 will walk you through the confi guration steps
in this window. As you select items, the corresponding fi elds that
you need to fi ll out will become available. Fields that do not pertain
to the confi guration at hand will be greyed out.

● Not Confi gured – Select this if this relay will not be used.
● Above/Below Options – These options work with the Hi
Limit and Lo Limit Setpoints. See Figure 35.
• On Above / Off Below • On Above / On Below
• Off Above / On Below • Off Above / On Below
● Follow Active/Inactive Binary Input Options – If one
of these options is selected, you must then go to the Binary
Input to Follow fi eld (see Figure 44, page 25)—and select
which Binary Input this Relay Output will be associated
with. If the Follow Active Binary Input is selected, this relay
will energize when the selected Binary Input is Active. If
the Follow Inactive Binary Input is selected, this relay will
energize when the selected Binary Input is Inactive. For
example, if the Main Control Method is “Follow Active
Binary Input” and the Binary Input chosen is confi gured
“N/O Contact (Closes for Active)”, then this relay will
be energized when 24 VAC is applied to the binary input
and the N/O contact closes (Active). If the Binary Input
chosen is “N/C (Opens for Active)”, then this relay will be
energized when 24 VAC is removed from the binary input
and the N/C contact opens (Active).
• Follow Active Binary Input • Follow Inactive Binary Input
● Follow Relay Output – If this option is selected, you must
then go to the Relay to Follow fi eld (Figure 45, page 25)
and select another relay that this relay is to follow. For
example, if you are confi guring Relay #1, you can confi gure
it to energize whenever Relay #2 (based on its logic)
energizes.
