Note: Total current for digital relay outputs O1-O4 cannot exceed 6A.
Note: It is forbidden to use a fuse with current exceeding 6 A! Higher current may permanently
damage the device and cause danger to the user and to the equipment!
2.2.1. 24 V AC power supply for external equipment
iSMA-B-FCU-HH is equipped with a 24 V AC, 7 VA power supply output to supply an external
equipment like sensors and actuators. This power supply uses a separate coil in the transformer.
24 V AC power supply terminal connection is labeled L2, N2.

2.3 Connecting the communication bus (RS485)
Figure 7 RS485 connection
2.3.1 RS485 grounding and shielding
This device can be exposed to electromagnetic field. Electromagnetic radiation can induce
electrical noise into both power and signal lines, as well as direct radiation into the FCU device with
negative results for the system. Appropriate grounding, shielding and other protective steps should
be taken at the stage of installation to prevent these effects. These protective steps include
grounding the control cabinet and the cable shield, installing protective elements for
electromagnetic switching devices, correct wiring, as well as proper choice of cable types and their
cross sections.
2.3.2 RS 485 network termination
Transmission line effects often present a problem for data communication networks. These
problems include reflections and signal attenuation.
To eliminate the presence of reflections of signal from the end of the cable, the cable must be
terminated at both ends with a resistor across the line adequate to its characteristic impedance.
Both ends must be terminated since propagation is bidirectional. In case of an RS485 twisted
pair cable this termination is typically 120 Ω.
iSMA-B-FCU /FCU Hardware
Version 1.1 www.gc5.pl Page 12 / 37
2.4 RJ12 Panel connection
RJ12 socket is designed for connecting external modules and LCD panel. The ISMA-B-FCU
device has two parallel sockets with the same pin configuration. Those sockets provide
communication in Modbus RTU protocol.
RJ12 socket provides also power supply dedicated for external LCD panels with maximum load
up to 2.5 W. Before connecting devices powered from RJ12 please calculate the power supply
load. Power consumption of the dedicated wall panel iSMA-B-LP with temperature sensor is 0.5
W, so the maximum number of panels on the bus is 5.
RJ12 pins are shown in the figure below.
Figure 8 RJ12 pin description
For short distance, up to 100 m, it is recommended to use the following cables for connection:
standard category 3, 4 wire or 6 wire telephone cable straight without crossing (for example
YTLYP 6x0.12). For longer distance, it is recommended to use twisted shielded Modbus standard
cable.
2.5 Mini USB Port
The iSMA-B-FCU device has a built-in mini USB port designed to manage controller firmware and
application, as well as for diagnostics.
This USB port also provides controller power supply for commissioning processes and for
application diagnostics. When the controller is powered up by a USB, all inputs and outputs are
operational (except for Triac Outputs which require external power supply).
2.6 Front panel LED functions
The ISMA-B-FCU device is equipped with 4 LED diodes for quick status check and diagnostics:
• Power LED lights up (green) after turning the power on.
• Communication LED lights up (orange) for 20 ms after sending each package through the main
RS485 port. As long as module receives/sends packages, the Communication LED blinks
continuously.
iSMA-B-FCU /FCU Hardware
Version 1.1 www.gc5.pl Page 13 / 37
• Extension Communication LED lights up (orange) for 20 ms after sending each package
through the extension ports. As long as the module receives / sends packages, the Extension
Communication LED blinks continuously.
• User LED is OFF as default, the function is programmable through LED_ALARM component; it
blinks very softly when there is a fault during the start-up of Sedona virtual machine.
• During device reset, when Switch 6 in DIP switch PROTOCOL is in ON position (default settings
restoration mode), Power LED blinks in 300 ms time intervals. After Switch 6 is switched OFF,
Power LED is lit permanently and the default settings are restored.
• When the device remains in bootloader status, the Power LED and the Communication LED blink
alternatively. The communication LED keeps its functionality and blinks also after
sending/receiving data packages.

4 ISMA-B-FCU device outputs
ISMA-B-FCU device is equipped with three types of outputs: 2 Triac Outputs,
5 Digital Outputs, and 4 Analog Outputs.
4.1 Triac Outputs
ISMA-B-FCU device is equipped with two Triac Outputs designed for heating and cooling thermal
valve actuators. Depending on controller model, Triac Outputs can be connected to actuators
with 230 V AC supply (for iSMA-B-FCU-HH) or to actuators with 24 V AC supply (for iSMA-B-FCUHL and iSMA-B-FCU-LL). In iSMA-B-FCU-HL, Triac Outputs are supplied with 24 V AC from a buildin transformer, whereas in iSMA-B-FCU-LL and iSMA-B-FCU-HH Triac Outputs are connected
directly to Power Supply terminals.
Triac Outputs can work as typical binary outputs (for Binary Temperature Control) or with PWM
modulation. PWM mode has two parameters:
• Duration time in seconds (this value depends on valve parameters)
• Fill out (percentage value of signal fill out).
The figure below presents the way actuators are connected to Triac Outputs (for
4 pipes mode).
Figure 17 Connection between Thermal Valves and Triac Outputs: a) iSMA-B-FCU-HH; b) iSMA-B-FCU-HL, and iSMA-B-FCU-LL
WARNING!
In case of iSMA-B-FCU-HH or iSMA-B-FCU-LL controller, the actuators connected to each Triac
Output may consume up to 0.5 A under constant load. In some cases the current can be higher
for a limited time, 1.5 A up to 30 seconds.
In case of iSMA-B-FCU-HL controller, the sum of power consumption of both Triac Outputs and
24 V AC output cannot exceed 0.3 A (7 VA):

ISMA-B-FCU device is equipped with three relay outputs, designed for connecting up to 3 speed
Fans. The way the Fans are connected (depending on the number of speeds) is presented in the
figure below. The common terminal for those outputs is connected directly to Power Supply “L”
terminal.
WARNING! Outputs O1-O3 and output O5 are protected by a built-in 6 A fuse. Total current for digital
relays outputs O1-03 and O5 cannot exceed 6 A.
WARNING! It is forbidden to use a fuse with current exceeding 6 A! Higher current may permanently
damage device and cause danger to the user and to the equipment!

version of the FCU controller.
WARNING! This digital output is equipped with a separate circuit with 10 A relay. This circuit
requires using external fuse protection up to 10 A. The current higher than 10 A may permanently
damage device and cause danger to the user and to the equipment!
Figure 19 Digital Output O4, exemplary Electrical Heater connection
4.2.3 O5 – CLG relay “Electrical Cooler”
ISMA-B-FCU device is equipped with a relay output, which in FCU application is dedicated to an
external Cooler. This relay output is internally connected to the power supply, therefore there is no
need to connect external supply. In iSMA-B-FCU-HH and iSMA-B-FCU-HL the output voltage in high
state is 230 V AC, and in iSMA-B-FCU-LL version the high state voltage is 24 V AC. Current
consumption cannot exceed 6 A. An exemplary way of connecting is presented in the figure below.
WARNING! Output O4 and outputs O1-O3 are protected by a 6 A fuse. Total current for digital relay
outputs cannot exceed 6A.
