Range Default Appears If
sp;ll
[SP.LL] Limit
Set Point Limit Low
Clamp the operational limit low maximum
setting to this value.
-1999.000 - 9999.000 -1999.000 always
[`L;it]
[ L.it] Limit
Integrate
In a limit state the controller will turn off
the outputs, terminate an active profile
and freeze PID and TRU-TUNE+
®
calcula-
tions.
[``no] No
[`YES] Yes No always

[`h;Ag]
[ h.Ag] Loop
Heat Algorithm
Set the heat control method.
[`oFF] Off
[`Pid] PID
[on;of] On-Off PID always
[`C;Ag]
[ C.Ag] Loop
Cool Algorithm
Set the cool control method.
[`oFF] Off
[`Pid] PID

[`C;Cr]
[ C.Cr] Loop
Cool Output Curve
Select a special cool output curve to
change the responsiveness of the system.
[`oFF] Off
[`Cr;A] Curve A
[`Cr;b] Curve B Off Cool Algorithm is set to
Off.
[t;tUn]
[t.tUn] Loop
TRU-TUNE+
® Enable
Enable or disable the TRU-TUNE+
®
adaptive tuning feature.
[``no] No
[`YES} Yes No Cool Algorithm or Heat
Algorithm is set to PID.
[t;bnd]
[t.bnd] Loop
TRU-TUNE+
®
Band
Set the range, centered on the set point,
within which TRU-TUNE+
® will be in ef-
fect. Use this function only if the controller
is unable to adaptive tune automatically.

able is set to Yes.
[`t;gn]
[ t.gn] Loop
TRU-TUNE+
® Gain
Select the responsiveness of the TRU-

More responsiveness may increase over-
shoot.

Autotune Aggressiveness
Select the aggressiveness of the autotun-
ing calculations.
[Undr] Under damped
[Crit] Critical damped
[ouer] Over damped Critical Cool Algorithm or Heat
Algorithm is set to PID.
[`UFA]
[ UFA] Loop
User Failure Action
Select what the controller outputs will do
when the user switches control to manual
mode.
[`oFF] Off, sets output power
to 0%
[bPLS] Bumpless, maintains
same output power, if it was
less than 75% and stable,
otherwise 0%
[MAn] Manual Fixed, sets
output power to Manual
Power setting
[USEr] User, sets output
power to last open-loop set
point the user entered
Off always
Note: Some values will be rounded off to fit in the four-character display. Full values can be read with other interfaces.
If there is only one instance of a menu, no submenus will appear.
