Sporlan Temperature Control
Quick Reference Guide
SD-375/092012 Controller v. A
The Sporlan Temperature Control should be installed only by a qualified professional. All other system components (valves and sensors)
should be supplied by Sporlan to ensure compatibility and proper operation. There are no user-serviceable components inside the
Temperature Control. Opening the case will void the warranty.
1. INSTALLATION
Reference diagrams on the back of this
guide.
Maximum torque on screw terminals
is 3.5 in-lbs.
1. Mount the controller in a rain-tight,
protected location using the supplied
DIN rail. To leave enough working
space, the suggested mounting area is 10
inches high and 5 inches wide. The min-
imum depth is 3 inches.
2. Mount the temperature sensor, T1, per
the evaporator manufacturer’s
recommendation. Connect the sensor
wires to terminals 31 and 32. The
sensor is not polarized.
3. Mount the second temperature sensor,
T2 (optional). Connect the sensor wires
to terminals 29 and 30. The sensor is
not polarized.
4. Connect terminals 25 and 26 to a digital
input. A short or closed contact from an
external relay will enable pumpdown.
5. Connect the Sporlan electric valve wires
to terminals 5, 6, 7, and 8, matching the
colors shown in the wiring diagram.
6. Connect power wires to terminals 1 and
2. Power requirements are 24 volts AC
at 40VA, Class II transformer.
7. Remove the protective clear film cover
from the front of the Temperature Control.
Use caution when working around high voltage components.
Safety covers should be used for personal safety on high voltage panels.
Tools required:
• Small flat screwdriver for terminal
• Cordless screwdriver
• Phillips and flat screwdrivers
• Needle-nose pliers
• Wire cutters
• Two #8 x ½"self tapping screws to
mount DIN rail
2. SETUP
Once powered up, the controller will
display the firmware version and then
prompt for three system variables to be set.
The electric valve is closed upon startup,
and the system will not operate until
completing setup:
1. Set tSP, Temperature Setpoint. Press
and then turn the SELECT knob to
set the operational setpoint. Press the
SELECT knob again to save the value.
The next variable is displayed.
2. Set STEP, Valve Steps. Select the correct
number of steps for the valve being used.
Press the SELECT knob to save the
value. The next variable is displayed.
3. Set trud, Temperature Rise Valve
Direction. Select Open on Temperature
Rise (OPTR) or Close on Temperature
Rise (CLTR). Press the SELECT knob
to save the value.
Setup is complete. The Temperature
Control will begin controlling based on
default values, and is now displaying tSI.
The controller is now in the Process Values
Menu. Rotate the knob to view values.
3. OPERATION
For further system setup or system tuning,
adjust parameters through the Setpoint
Menu as described below. See the
Temperature Control installation and
Operation Manual for a complete list of
setpoint parameters and definitions.
1. Enter the Setpoint Menu: Hold down
the SELECT knob for 5 seconds.
Rotate the knob to enter the controller
password and press the SELECT knob
again. The default password is “111”.
2. To select a parameter, rotate the
SELECT knob to the desired parameter.
Press the SELECT knob to display the
current parameter value.
3. To change a parameter, rotate the
SELECT knob to the desired value.
Press the SELECT knob again to select
the value.
4. After all parameters are set, rotate the
SELECT knob to “ESC”. Press the
SELECT knob to save all changes.
Note: After 60 seconds of inactivity, the
Setpoint Menu times out and all
changes entered will be lost.
Note: Not all refrigeration systems
are designed alike. See the
Temperature Control Installation
and Operation Manual to adjust
the settings according to the
specic needs of the system.
