Dual Output with PID Control
Only available on the SOLO Basic units with alarms. When used in a dual output mode the output for Alarm 1
is reassigned as Output 2. Output 2 and Alarm 2 will share the same common in this configuration and should
be taken into consideration when planning unit wiring.
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

. Use the
.
or
,
button to select
h1C2
for controlling a dual heating / cooling loop or
C1H2
a dual cooling / heating loop. The
h1C2
setting will
assign the heating control to Output 1 and the cooling control to Output 2 and
C1H2
will assign 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. To adjust the control cycle for Output 1 access the regulation mode again by pressing the
;
button for less
than three seconds. Press the
•
button repeatedly until the parameter
o1-H
or
o1-C
appears if heating or cooling is assigned to Output
1. Use the
.
and
,
buttons to set the time period in seconds for
the control cycle of Output 1. Press the
;
button to save the value.
To adjust the control cycle for Output 2 press the

button repeatedly
until the parameter
o2-H
or
o2-C
appears if heating or cooling is
assigned to Output 2. Use the
.
and
,
buttons to enter the cycle
period in seconds for Output 2. Press the
;
button twice to save the
value and return to the controller main screen.
5.Optional regulation parameters can be programmed for dual output
control. If this is desired, access the regulation mode again by pressing
the
;
button for less than three seconds. Press the
•
button repeat-
edly until the parameter
Coef
appears. This value allows the control
selected for Output 2 to have a different proportional setting than the
control selected for Output 1. The Output 1 proportional band setting is
multiplied by the
Coef
value to create a proportional band setting for
Output 2. 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 affected by the proportional control value. If
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.

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 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
. Press the
;
button to save the selected value. The same process can be followed for
out2
on units with alarms configured for dual output. Refer to Section 12-7 or 12-8.

Control Setup
Please choose the desired control mode and follow the instructions in that section. For example, to control
heat in an oven, the Heating Loop with PID Control could be used by following the steps in 12-2. For a cooling
operation like a freezer one could use Cooling Loop with ON / OFF Control in section 12-5.
To change the control mode, it is recommended to do a factory reset before setting up the new control mode.
Please see section 10 of this document for instructions on how to complete a reset to factory defaults.
