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.

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
