BEFORE INSTALLATION
ECFWEB6 INSTALLATION INSTRUCTIONS
Built-in type controller
Installation on the support and on the fan
coil
It is advisable to set the microswitches before installing
the controller, see paragraph "Setting the microswitches"
on page 10.
The controller can be installed on both sides of the unit
using a support and a cover plate.
Proceed as follows to install the controller.
1 Unscrew the four screws hidden behind the hatches
at the end of the grid and remove the fan coil cabinet
(See figure 6).
2 Remove the blank plastic tabs from one of the two
slots of the support to be able to reach the "fast-on's"
of the controller (see figure 4). (The supplied cables
with fast-on's will need to pass through one of the
slots of the support, depending on whether the
controller is to be installed on the right hand or left
hand side of the unit).
3 Feed the cables of the probes if any, in one of the
slots of the support and secure the support and
controller together using the two screws supplied.
(See figure 10, it illustrates the installation of the
support and controller when the controller is to be
installed on the right hand side of the unit. If the
controller is to be installed on the left hand side of the
unit, the support is to be turned by 180° compared to
the drawing).
4 Complete all electrical connections according to the
wiring diagrams.
5 Once the electrical connections have been
completed, it is advisable to execute the
autodiagnosis procedure to verify functioning of all
outputs before you finish installation of the controller
(outputs of the fan at various speeds, of the valves
and electric heaters if installed): Refer to the
paragraph "Installing the air and water temperature
probes" on page 11.
6 Assemble the controller-support unit on the fan coil
using the bayonet fittings (see figure 11).
7 Install the air temperature probe (black) and water
temperature probe (white) (see figures 13 unto 20)
following the instructions given in the paragraph
"Installing the air and water temperature probes" on
page 11.
8 Fit the cabinet back in place fix it with the four screws
and then insert the correct cover plate, as illustrated
in figure 12.
■ All field wiring and components must be
installed by a licensed electrician and must
comply with relevant local and national
regulations.
■ Before obtaining access to terminals, all
power circuits must be interrupted.
The controller has been specially designed for
FWV and FWL units; if used to control other
units, make sure its operation limits are
respected.
1 Support
2 Blank tabs
Ensure that all terminals required for the
electrical connections foreseen in the
configuration chosen (valve, electric heater,
external contacts, ...) can be accessed, even
after the support has been installed (see the
correct wiring diagram). If this is not the case,
remove the protective blank tabs from the
base of the support first.
