On/Off Cool Hyster. On/Off Cool Hysteresis. Set the control
switching hysteresis for on-off control. This
determines how far into the “on” region the
process value needs to move before the out-
put turns on.

Time Integral Set the PID integral for the outputs. 0 to 9,999 seconds per
repeat
180 seconds

8006
Time Derivative Set the PID derivative time for the outputs. 0 to 9,999 seconds 0 seconds 8007
Dead Band Set the offset to the proportional band. With a
negative value, both heating and cooling out-
puts are active when the process value is near
the set point. A positive value keeps heating
and cooling outputs from fighting each other.

TRU-TUNE+ Band The range, centered on the set point, within
which TRU-TUNE+ will be in effect. Use this
function only if the controller is unable to
adaptive tune automatically.
0 to 100 0 8034
TRU-TUNE+ Gain The responsiveness of the TRU-TUNE+ adap-
tive tuning calculations. More responsiveness
may increase overshoot.
1 to 6 3 8035
Autotune Start an autotune.
While the autotune is active, the Home Sceen
will display Tuning 1.
When the autotune is completed, the mes-
sage will clear automatically.

No 8026
Autotune Set Point Set point that the autotune will use, as a per-
centage of the current set point.

Autotune Aggressive The aggressiveness of the autotuning calcula-
tions.
Under damped (99)

Peltier Delay A value that will cause a delay when switching
from heat PID mode to cool PID mode.

Remote Set Point Whether this loop will use a remote set point. No (59) Yes (106) No 7021
Remote Set Point Type Set what type of set point will be used. Auto (10 Manual (54) Auto 7022
Auto-to-Manual Power Select what the controller outputs will do when
the user switches control to manual mode.
Off: sets output power to
0% (62)
Bumpless transfer: main-
tains same output power,
if it was less than 75% and
stable, otherwise 0% (14)
