appears. Confirm the default value
Pid
is selected for PID
control. Press the
'
button to access the parameter

.
Confirm the default value
heat
is select-
ed for controlling a heating loop. Press the
;
button to return to the controller main screen.
2. Press the
'
button to access the parameter
r-s
. Verify that the default value
run
is selected. Press
the
;
button to return to the controller main screen.
3. Refer to Section 12-1 of this Quick Start Guide to set up the PID control parameters.
4. If the temperature controller’s output #1 is discrete, access the regulation mode again by pressing the
;
button for less than three seconds. Press the
'
button repeatedly until the parameter
htpd
appears. Use
the
,
and

There are four groups for storing PID parameters,
pid0
(PID0) -
pid3
(PID3). Press the
;
button for
less than three seconds and press the
'
button repeatedly until the parameter
pid0
appears. Use the
,
and
.
buttons to select which group to use for storing the PID parameters. Press the
;
button to
confirm the setting. The groups
pid0
-
pid3
can be individually set up with different SV values to be used
in the control process. If the group
pid4
is selected, the controller will automatically select the most useful
PID parameters based on the current temperature setting and the SV value set in each PID group.
The parameters for PID can be auto-tuned using the
At
parameter. Access this parameter by pressing the

control to output #2. Press the
;
button twice to save the value and return to the controller main screen.
2. Press the
'
button to access the parameter
r-s
. Verify that the default value
run
is selected. Press

5. Optional regulation parameters can be programmed for a second
control output. If this is desired, access the regulation mode again by
pressing the
;
button for less than three seconds. Press the
'
button repeatedly until the parameter
Coef
appears. This value allows
the cooling control to have a different proportional setting than the heating
loop. The heating loop proportional band setting is multiplied by the
Coef
value to create a proportional band setting for the cooling loop
control. Use the
,
and
.
buttons to change this value if desired.
Press the
;
button to save the selected value. Press the
'
button to
access the parameter
dead
. Use the
,
and
.
buttons to enter a
deadband zone value around the setpoint where the output is not effected
by the proportional control value. As long as the PV remains within the
deadband zone the output is not affected by the proportional control. The
integral and derivative controls ignore the deadband setting and may
cause the output to be on within the deadband zone. Press the
;
button twice to save the value and return to the controller main screen.
