The SCCI Interface provides the SCC4 (modulating
boiler control) with the capability of receiving an
external Set Point as a 4-20mA signal through an
Energy Management Systems or Building Management
Systems (EMS/BMS). In addition, the SCC4 can be
shutdown by the EMS/BMS system.

• The signal must be a two-wire 4-20mA.
• A system sensor must be installed to the SCC4.
• The External Set Point must be set up correctly (See SCC4
documentation). These settings will allow the SCC4 to read and
monitor the system temperature and also monitor the 4-20mA input
to remotely adjust the set point to the desired value.
• The SCCI Interface can source the current for the 4-20mA input
signal. It provides an excitation DC current. If using the SCCI
Interface to source the power, attach the (+) side of the EMS/BMS
signal to the SCCI Interface terminal marked +. Attach the (-) side
of the EMS/BMS signal to the SCCI Interface terminal marked
SIGNAL.
• If the EMS/BMS or other equipment signal sources the current
(provides the excitation voltage), attach the (+) side of the 4-20mA
input to the SCCI Interface terminal marked SIGNAL. Attach the
(-) side of the 4-20mA input to the SCCI Interface terminal marked
GND.

• The SCCI Interface connects to the SCC4 using an RS485 (phone plug).
• When having to use the RS485 to connect to Extensions, use the extra RS485 (phone plug).
• The control, SCCI Interface and two Extensions can be connected in series using the RS485.
