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
the
;
button to return to the controller main screen.
3. Press the
;
button for less than three seconds to access the
parameter
hts
. Use the
,
and
.
buttons to enter hysteresis
for output #2, the heating control. This is the amount the PV must go
below the SV before the controller output turns on. Press the
;
button to save the selected value. Press the
'
button to access the
parameter
Cts
. Use the
,
and

button twice to save the selected value and return to the controller
main screen.
4. Optional regulation parameters can be programmed for additional dual loop control. 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
dead
appears. Use the
,
and
.
buttons to enter a deadband zone value
around the setpoint where the output is not on. The PV must go beyond the deadband range in order for either
the heating or cooling output to turn on. Press the

Manual Control
1. Access the Initial Setup mode by pressing and holding the
;
button for three seconds. Press the
'
button repeatedly until the parameter
Ctrl
appears. Use the
,
and
.
buttons to select
manu
for
manual control. Press the
;
button twice to save the selected value and return to the controller main screen.
2. Press the
'
button to access the parameter
out1
. Use the
,
and
.
buttons to set a value
between
)0
and
10)0
to control output #1 directly. If the controller has a discrete output, a value of
2)0
turns the output on 20% of the time. A value of
10)0
would turn the output on 100% of the time. A manually
controlled analog output value is a percentage of the analog signal. For example, if the controller has a 4-20mA
current output, a setting of
)0
would mean that the output would be 4mA. The output would be 20mA with a
setting of
10)0
. Both types of manually controlled outputs are off with a value of
00
. Press the
;
button
to save the selected value. For dual output control, press the
'
button to access the parameter
out2
. Use
the
,
and
.
buttons to set a value between
)0
and
10)0
to control output #2 directly. Press the
;
button twice to save the selected value and return to the controller main screen.

Dual Cooling / Heating Loop with PID Control
1. Access the Initial Setup mode by pressing and holding the
;
button for three seconds. Press the
'
button repeatedly until the parameter
Ctrl
appears. Confirm the default value
Pid
is selected for PID
control. Press the
'
button to access the parameter
s-hC
. Use the
.
button to select
h2C1
for
controlling a dual cooling / heating loop. This parameter sets the cooling control to output #1 and the heating
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
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
Clpd
appears. Use
the
,
and
.
buttons to set the time period in seconds for the cooling output. Press the
;
button to save
the value. If the temperature controller’s output #2 is discrete, press the
'
button repeatedly until the param-
eter
hCpd
appears. Use the
,
and
.
buttons to enter the cycle period for output #2, the heating output.
Press the
;
button twice to save the value and return to the controller main screen.
5. Optional regulation parameters can be programmed for additional dual
loop control. 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 heating control to have a different proportional setting than the cooling
loop. The cooling loop proportional band setting is multiplied by the
Coef
value to create a proportional band setting for the heating 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.

'
button to access the parameter
ti00
. Use the
,
and
.
buttons to enter a time in hours / minutes for step 00. Follow this procedure until the desired
number of temperature and time parameters are completed. Press the
'
button to access the parameter
psx0
. Use the
,
and
.
buttons to select the last step to be completed by the Ramp /Soak pattern. For
example, if
psx0
is set to
4
, steps 00 through 04 will be executed in the pattern.
3. Press the
'
button to access the parameter
CYC0
. Use the
,
and
.
buttons to select the number
of additional times the Ramp / Soak pattern will be executed. For example, if
CyC0
is set to

, the Ramp /
Soak pattern will execute a total of four times. Press the
;
button to save the selected value. Press the
'
button to access the parameter
lin0
. Use the
