PRODUCT DESCRIPTION
e TCMF8-WF/EW are universal fan speed controllers with Modbus RTU
communication and an integrated internet gateway. Multiple AC fans can be regulated
via the two TRIAC outputs (phase angel control). Via Modbus RTU communication
one or more HVAC sensors or potentiometers can be connected to this controller.
Application specific firmware is required. is firmware can be downloaded via
SenteraWeb. Typical applications are destratification, air curtain control, heat
recovery unit control, etc. ese TCMF8 versions have a built-in internet gateway to
connect to SenteraWeb.

MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting the TCMF8-DM, read carefully “Safety and Precautions”
and follow these steps. Choose a smooth solid wall surface for installation.
Follow these steps:
1. Switch OFF the main power supply.
2. Unscrew the front cover and open the enclosure. Mind the wires that connect the
potentiometer with the printed circuit board.
3. Fix the unit onto the wall or panel using the provided screws and dowels. Mind the
correct mounting position and unit mounting dimensions. (See Fig. 1 Mounting
dimensions and Fig. 2 Mounting position.)
4. Pay attention to the following instructions in order to minimize the operating
temperature:
►Respect the distances both between the wall / ceiling and the device and
between two devices as shown in Fig. 2. In order to ensure sufficient ventilation
of the controller, clearance on every side has to be maintained.
►When installing the device, please keep in mind that the higher you install it,
the warmer the device will get. For example, in a technical room the correct
installation height can be of great importance.

5. Insert the cables through the cable glands and do the wiring according to the
wiring diagram (see “Wiring and connections“) while adhering to the information
from section “Wiring and connections”.
►Connect the AC fans (terminals U2, U1 and PE);
►Connect the supply voltage (terminals L, N and PE);
►Connect the sensors via the RJ45 socket or via the Modbus terminal block.
►If applicable, connect the analogue input signal(s)
6. Put back the cover and secure it with the screws. Tighten the cable glands.
7. Switch on the power supply.
8. Connect your installation to SenteraWeb and download the required application
specific firmware.
9. Switch ON the main supply after all connections are done and checked.
*Not respecting the above listed rules can reduce service life and relieves the manufacturer of any responsibilities.

Download and Install Sentera Solution Firmware
e TCMF8 controller requires application dedicated firmware, which can be
downloaded from the Sentera website: Select your application via www.sentera.
eu/en/solutions.
First, connect all required products including the Sentera internet gateway. en
connect your installation to www.senteraweb.eu. Enter the solution code and click
“Link to solution” to download the selected firmware into the connected devices.
After the download there is the possibility to use the installation stand alone or to
keep the internet gateway connected.
Tact switch
Press and hold the tact switch for at least 5 seconds to reset the unit to its default
values:
■default Connection Type: Ethernet
■default Connection mode: DHCP
■default Modbus communication parameters: 19200 Bps, 8 bits, even parity, 1 stop
bit (8,E,1)
■default gateway host page: 192.168.1.123

Reset buttons
1. Left button - for Wi-Fi reset
In case of connection problems or in order to clean the memory of the Wi-Fi module,
press and hold for 4 seconds until the blue LED (LED2) lights up (see Fig. 5). After
this, the password inside the memory (to connect to a Wi-Fi Access point) has been
erased and the default IP address 192.168.1.123 is restored. Now you can restart the
installation procedure as explained in the User Guide that can be downloaded from
the Sentera Website.
2. Right button - for developers only!
e ‘Program’ button (see Fig. 5) is only needed to restart the microcontroller of
the unit for development or debug purposes, such as to enter bootloader mode to
reprogram the module. You should NOT press this button in any other cases!

VERIFICATION OF INSTALLATION
After connecting the unit to the main supply, the green LED on its cover should light
up to indicate that the controller is supplied.
Safe operation depends on proper installation. Before start up, ensure the following:
■e main supply is connected correctly.
■ere is sufficient air flow around the unit.
■Minimum voltage is selected based on the fan parameters - the entire fan
regulation range must be within its operating voltage.
■Maximum load current is according to the device selected, make sure the current
drawn by the fan does not exceed the current rating of the device!
■During operation, the unit must be closed.
■If the unit does not work according to the instructions, the wiring connections and
settings need to be checked.
ATTENTION Disconnect main power supply before all servicing and maintenance. High Voltage on
the internal circuit!
ATTENTION High temperatures may occur during operation. Allow to cool before maintenance!
ATTENTION Drawing excessive current from the fan controller will cause the internal circuit
to overheat and fail.
TRANSPORT AND STORAGE
Avoid shocks and extreme conditions; stock in original packing.
