The actuator types FlowCon FN.0.2, FN.0.2-
BUS
and
FN.0.4
are electrical actuators.
•FN.0.2 is 24V modulating.
• FN.0.2-BUS is 24V modulating with Modbus or
BACnet communication.
• FN.0.4 is 24V 3-point floating and 2-position.
Fitting and Re-tting
Do not connect power to the actuator unless
the actuator is already fitted on the valve
and NEVER install the actuator in closed
position - this may damage the valve. Actu-
ator is supplied in open position to ensure
easy commissioning of the system.
Mount the actuator on the valve and finger
tighten the connection union. Do not use addi-
tional tools.
In case the actuator will have to be removed, it is
recommended for FN.0.2 and FN.0.4 to electri-
cally open the actuator by activating DIP switch
#6 for easier removal.
For FN.0.2-BUS set DIP switch #1-6 to OFF and
wait until the LED indicator is blinking green.
Hereafter, disconnect power and finger loosen
the connection union. Again, no need for addi-
tional tools. Please make sure that the actuator
is electrically opened, before re-fitting it on the
valve.
Orientation
Upside-down installation is allowed along with
the standard horizontal and vertical installation.

Start-up Sequence
When power to the actuator is turned on, the
actuator will automatically calibrate to determine
closing point. Hereafter it will proceed to normal
operation mode (according to control signal).
For FN.0.2-BUS, bus address configuration is
required and must be done immediate after first
power on. Calibration mode and then normal op-
eration mode will follow thereafter.
Auto Cycle Sequence
Auto Cycle can be activated during commission-
ing. It prevents the valve from jamming when
the valve is not moved for a longer period of
inactivity. For FN.0.2 and FN.0.4 Auto Cycle is
activated by moving DIP switch #1 from OFF to
ON. The actuator will then perform 50% stroke
cycle every 3 weeks if not stroke movement has
occurred.
For FN.0.2-BUS Auto Cycle is activated and cy-
cle time configured via the bus (Modbus register
136 and BACnet AV.10; 0= not activated).
Override
For FN.0.2 and FN.0.4 electrical override is acti-
vated by moving DIP switch #6 from OFF to ON.
Then the valve will open fully. During override
mode the LED indicator will blink red and green.
When DIP switch #6 is moved back to OFF, the
actuator will re-calibrate and thereafter go into
normal operation mode. Electrical override is
performed with power supply on.
When performing the manually override proce-
dure on the FN.0.2-BUS, set DIP switches 1 to
6 to OFF and the spindle will fully retract, and
the LED will rapidly blink green. In this state the
valve can be manually close or opened using a
magnet.
To extend actuator spindle and fully close the
valve, briefly swipe the magnet along the right-
hand side of the actuator (top view and wires
downwards). LED indicator is blinking yellow
during this ‘manual spindle adjustment’ mode. To
retract the actuator spindle and open the valve
fully (mounting position), again briefly swipe the
magnet along the right-hand side of the actuator.
LED is blinking rapidly green to indicate ‘mount-
ing position’ mode. Manually override can be re-
peated as often as necessary.
Flush Mode (FN.0.2-BUS)
The automatic Flush Mode is activated and
cycle time configured via the bus (Modbus reg-
ister 132 and BACnet AV.35; 0= not activated).
In Flush Mode, the valve is temporarily fully
opened independent of the control signal to al-
low easy system flushing.

The valve functions are set on DIP switches found under the connection cover. PCB mounted electri-
cal components will not be directly exposed when DIP switches are to be set. Factory setting for all
switches is OFF.

Re-Calibration
FN.0.2
Re-calibration can be achieved in one of 2 ways:
1. Forced individual actuator re-calibration can also be performed by flipping DIP switch #6
from OFF to ON and back to OFF on the relevant actuator.
2. Forced concurrent re-calibration for all modulating actuators is electrically possible. Within 60
sec. provide the following electrical control signal sequence to the grey wire: 10V-2V-10V-2V-
10V-2V to achieve re-calibration.
After re-calibration the actuator will go into normal operation mode.
FN.0.2-BUS
For FN.0.2-BUS change MSV.1 to 2 (BACnet) or register 138 to 1 (Modbus).
After re-calibration the actuator will go into normal operation mode.
FN.0.4
Forced individual actuator re-calibration can also be performed by flipping DIP switch #6 from OFF
to ON and back to OFF on the relevant actuator.
After re-calibration the actuator will go into normal operation mode.

BUS programming of
FlowCon FN.0.2-BUS
When using FN.0.2-BUS actuator and BUS
communication, setting on the Green/GreEQ in-
sert MUST BE be 5.0.
In this instruction default values are underlined.
Please see FlowCon FN.0.2-BUS Modbus Data
Point List or BACnet PICS for more detailed in-
formation.
Initiate by setting Baud Rate (register 105 or
MSV.7). Set actuator DIP switches 1-6 to write-
able mode, i.e. 1-1-1-1-1-1-1 and set MAC Ad-
dress via bus communication (register 104 or
AV.28) and proceed by selecting your PICV
valve in register 110 or MSV.8:
Reg. 110 MSV.8 Selected valve
0 1 (generic linear)
1 2 Green.0
2 3 Green.1
3 4 Green.2
4 5 Green.1HF
5 6 GreEQ.0
6 7 GreEQ.1
7 8 GreEQ.2
8 9 (generic EQ%)
9 10 user-valve
And select your PICV control mode in register
103 or MSV.13:
Reg. 103 MSV.13 Selected control mode
0 0 (linear)
1 1 Equal%
Set Operating Mode in register 200=0 or
MSV.4=1 and provide Control Signal in register
400 or AV.1 (0% to 100%).
Condition of the FN.0.2-BUS
through BUS
Check the Current Flow (not measured) in
register 402 or AI.7.
Status Information is available in BI.3 and
Error Information is available in BI.4, BI.5,
BI.6 and BI.7. This is combined for Modbus in
register 318 and 407.
Service Commands and resetting is avail-
able in register 138 or MSV.1
