Remote type controller
Installation
It is advisable to set the microswitches before installing
the controller, see paragraph "Setting the microswitches"
on page 10.
The remote controller can be installed to a wall.
Proceed as follows to fit the controller.
1
Remove the controller lock screw
and remove the
cover.
2
Drill 2 holes in the wall where the controller shall be
installed, at the exact same position of the fixing slots
(5 x 8 mm) located on the control base (see figure 9).
3
Make the electric connections to the control terminal
board according to the wiring diagram of the selected
configuration.
4
By means of screws, fix the control base to the wall.
5
Reassemble the control cover part and make sure
the rotating knobs are in the same position as they
were upon disassembly. Secure the controller lock
screw back into place again.
6
Make the electric connections to the unit according to
the wiring diagram of the selected configuration.

ETTING
THE
MICROSWITCHES
1

(See figure 7)
To facilitate its re-installation, be careful not to
modify the position of the 2 rotating knobs on
the controller cover (operating mode selector
switch and thermostat) and of the
corresponding potentiometers fit on the
electronic PCB.
When installing the ECFWER6 controller on
units with a current consumption greater than
1 A, you must install an additional EPIMSA6
Master/Slave interface or EPIA6 Power
interface (see "Master/Slave interface and
Power interface" on page 11).
To facilitate its re-installation, be careful not to
modify the position of the 2 rotating knobs on the
controller cover (operating mode selector switch
and thermostat) and of the corresponding
potentiometers fit on the electronic PCB.

if the desired configuration does not include
the electric heaters control function and the
operating mode selector switch is turned to the
electric heater symbol, the fan coil will
continue to run with an automatic fan speed
and will regulate the air temperature by means
of the fan.
