MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting the unit, read carefully “Safety and Precautions”and
follow these steps. Choose a smooth solid wall surface for installation.
Follow these steps:
1. Make sure that the controller is switched off.
2. Unscrew the front cover and open the enclosure. Mind the wires that connect the
LEDs with the printed circuit board.
3. Fix the unit to 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. Insert the cables through the cable glands and do the wiring according to the
wiring diagram (see Table 1) while adhering to the information from section
“Wiring and connections” above.
4.1 Connect the power supply line (terminals L and N).
4.2 If applicable, connect the analogue / modulating inputs (terminals Ain1 &
GND / Ain2 & GND) to an external potentiometer or HVAC sensor with an
analogue / modulating output (0—10 VDC / 0—20 mA / PWM / digital (0
or1))

4.3 If applicable, connect the tacho inputs (if the connected motor features
tacho, these are used for feedback and control).
4.4 Connect the analogue output(s) (Aout1, GND & Aout2). e controller can
be used to control one or two motors simultaneously, so only one or both of
these outputs can be connected, depending on your application.
4.5 If applicable, connect the Modbus RTU communication cables.
4.6 If your device is ECMF8-EW version, connect the Ethernet cable (Ethernet
connection is the default setting).
4.7 Connect HVAC sensors, potentiometers or other slave devices to the RJ45
socket and/or Power over Modbus (PoM) terminal block (see Fig. 3).
5. Put back the cover and secure it with the screws. Tighten the cable glands.
6. Switch ON the main supply after all connections are done and checked.
7. Connect your installation to SenteraWeb and download the required application
specific firmware.

First, connect all required products. 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.
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. For status indication, see Table 2.
Table 2 LED indications
Green Normal operation
Blinking Yellow Off level activated for input 1, 2 or both.
Blinking Red Communication with external sensors is lost.
Safe operation depends on proper installation. Before start up, ensure the following:
■e main supply is connected correctly.
■Do not short-circuit the terminals or the input and output wiring.
■During operation, the unit must be closed.
■Switch ON the main supply after all connections are done and checked.
■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!
TRANSPORT AND STORAGE
Avoid shocks and extreme conditions; stock in original packing.
WARRANTY AND RESTRICTIONS
