1. Introduction
The SCS family is an electronic superheat controller solution that is designed for refrigeration applications using
either a Pulse Width or Stepper type expansion valve. It is designed to be mounted within the refrigerated space
for ease of installation on existing equipment. SCS-PB is designed to operate pulse valves, while the SCS-SB
is designed to operate stepper valves. Each of the controller types include a coil outlet temperature sensor,
and connectors for the valve and pressure sensor compatible with Sporlan valves and pressure sensors and
a 110/120-220/240 VAC power connection.
2. Installation
Tools required:
• Mobile iOS device with Bluetooth LE capability and
either cellular or Wi-Fi connectivity
• Small flat screwdriver (for Pulse Valve connector)
• Wire cutters
• Two #10 (5mm) mounting screws
• Magnet or magnetized screwdriver
• Scotch-Brite™pad
1. The SCS should be mounted in a UV protected
location where the mounting location will be
between -22°F and 120°F (-30°C and 50°C). The
controller and connections should be hermetically
sealed so the controller can be installed in wet
environments. Take care not to mount the unit in
such a way that it would block any air curtains of
a refrigerated display case. Mount the unit in such
a way that the Bluetooth ID on the label is visible
for ease of connecting to the unit via Bluetooth.
The controller MUST be mounted on a flat surface.
Mounting the controller on a surface that is not
flat or bends may cause damage to the controller.
Recommended torque varies by material, 13 to 17
in-lbs (1.47 to 1.92 Nm) should be sufficient.
2. Mount the coil outlet sensor that is included with
the SCS on the outlet of the evaporator coil. See
Appendix C for details.
3. Mount the suction pressure sensor and connect
the transducer cable. See Appendix C for details.
4. Connect the valve. If using a stepper valve, connect
the M12 connection to the valve and tighten to 10-
14 in-lbs. (1.13 to 1.58 Nm). If using a pulse valve,
connect the DIN connector to the pulse valve.
Tighten the DIN connector mounting screw to 3.5
in-lb (0.40 Nm).
5. Connect the power wires. The power connection
does not come with any connectors, so the con-
nection to power must be made in compliance

Appendix C: Sensor Installation
Mount the Pressure Transducer
1. Locate or install a ¼” SAE access fitting on the
suction line near the outlet of the evaporator.
Mount it at 12 o’clock on a free-draining horizontal
line to decrease the possibility of oil trapping.
WARNING: Remove pressurized refrigerant from
the line before installing the fitting.
2. Install the transducer, tighten it to 8 ft-lbs, and
check for leaks. Do not use a gasket or a washer.
WARNING: For safety, ensure that the correct
Schrader core is installed in the access fitting
and use caution when removing Schrader cap/
installing transducer to avoid contacting escaping
refrigerant.
3. Connect the pressure transducer cable to the
transducer.
4. Route and secure transducer cable away from hot
surfaces and high power A/C voltage lines.
5. Ensure pressure range and type (gauge or
absolute) are configured properly in the controller,
See Section 3 - SETUP.
6. After startup, use a gauge set to verify proper
pressure reading through the controller. An
improperly installed Schrader core can cause
erroneous pressure readings.
7. Check for leaks after system is in operation.
Mount the Suction Outlet Temperature Sensor
1. Per Appendix B - Wiring Diagram, the temperature
sensor should be installed 10-14 inches (25-36
cm) from the heat exchanger, on a free-draining
horizontal line. Minimize the distance from the
pressure transducer.
2. Use Scotch-Brite™to clean the copper line at the
installation location. Removal of the oxides and dirt
will increase sensor accuracy.
3. Fasten the suction temperature sensor as oriented
in Figure 2. Mount the sensor on the suction
line after the heat exchanger, near the pressure
transducer.
4. Route the cable away from hot surfaces and high
power A/C voltage lines.
5. Verify that the controller is configured properly for
the temperature sensor used (2K, 3K, or 10K), See
Section 3 - SETUP.
6. Wrap temperature sensor and copper tube with
foam insulation to minimize ambient temperature
effects (Figure 3).
