NOTE: For more information about how parameter settings affect the controller’s operation, see Chapter Five, Control
Methods and Features.
Active if controller is a 3 phase
system which only has one
zone.
NOTE: The parameters available are
dependent on the controller’s
input/output configuration. The system
does not operate unless this prompt is
set to something other than
[[n no on ne e]] .
NOTE: Changing this parameter will
restart the system.

(Control Zone 1
only, 3 phase only.)
Select the load type
for Zone 1.
Active: Always.
Go to
[lrn|U] , set the controller to
[`req] . Wait 5 sec. for auto-
matic input of data for con-
troller. The display will go back

Read/Adjust
Shows the value for
baseline voltage and
allows manual

value.
Adjust to
match voltage phase
to phase for delta/

loads or phase to
neutral grounded wye
loads.
Active if [``In] is set to [`nna]
current or
[Uolt]
voltage.
Go to [lrn|a] , set analog input to
low limit and set the controller
to
[``lO] low limit. Wait 5 sec.
for automatic input of low data
for controller. The display will
go back to
[idle] when done.
Go to [lrn|a] , set the analog
input to high limit and set the
controller to
[``HI] high limit.
Wait 5 sec. for automatic input
of high data for controller. The
display will go back to
[idle]
when done.
