Assembly
Assembly, set-up and connection of on-board control panels ECA644, ESE645,
ECA647, ESE648
The controllers have two independent clean contacts
for controlling a refrigerator unit, a boiler and a presence
input. The 2 tube versions have a 230V output to power
the summer and winter solenoid valve whereas the 4-tube
versions have two independent 230V outputs for controlling
a summer solenoid valve and a winter valve.
The 10 kΩ water temperature probe positioned in the
compartment on the battery regulations the minimum level
when heating (30°C) and the maximum level when cooling
(20°C).
The board also has a function when there is no water
probe, in such cases the fan stop thresholds are ignored.
Slide the control panel into its housing in the upper part
of the device and fix it with the two fixing screws (ref. A).
To install the connection box:
- open the box (ref. B);
- lock the lower tooth into its hole (ref. C) on the side of
the device;
- hook the upper part of the box to the side (ref. D);
- fix it with the two fixing screws (ref. E);
- connect the grounding cable to the fan coil body (ref. M)
using the fixing screws (the minimum force that must be
applied for tightening screws must be around 2N);
- connect the fast connector of the MOTOR to the other
on the board (ref. I) *;
- on the two GRID block terminals (ref. L) there is a bridge
that allows SLI and RSI versions to work without a
microswitch.
- For other versions, remove the bridge and connect the
two terminals originating on the grill safety microswitch*;
- connect the water probe to the H2 connector on the
device.
The water temperature probe controls the temperature
inside the batteries and determines when the fan starts
according to pre-set parameters (minimum operation
in winder and maximum in summer).** Check that
they are correctly inserted into the compartment on
the battery.
- Connect the electrics, tidy cables and fix them with
the three clevises supplied (ref. G);
- close the box with the 4 screws (ref. H);
- refit the vanity plate on the side of the unit;
- tighten the upper screws on the control panel;
- place the screw head covers in their housing on the
control panel;
* For versions with hydraulic connections on the right,
refer to the relevant paragraph
** The regulation also works without a water probe
connected

There are two dip switches on the controller circuit board
for configuring unit operation as per requirements.
- The night-time heating operation logic is modified by
using dip switch C:
- in the ON position, the fan is always off, and heats the
room using radiation and natural convection, as with
traditional radiators; in the off position it operates as a
normal fan.
- By positioning dip switch B to ON, when cooling, the
fan operates at the minimum speed even after having
reached the set point, to allow for more uniform
operation of the temperature probe and to avoid
layering in the air. With the cursor in the OFF position,
the functions are cycled (4 minutes ON, 10 minutes
OFF).
On closing the contact connected to the CP input (ref. A)
the panel is placed in stand-by mode.
If the contact is open the unit is active, if the contact is
closed it is deactivated when a key is pressed the
symbol flashes.
The input cannot be connected in parallel to that of other
electronic boards (use separate contacts).

- To position the temperature probe (ref. A):
- pass the probe through the hole on the shoulder (ref. B)
- insert the probe into the lower hole (ref. C)
- fix the probe on the relevant hook (ref. D)
By regulating these settings, the system can select either
heating or cooling automatically, excluding normal manual
selection. This setting is particularly suitable for 4-tube
versions. This regulation system can only be activated by a
qualified and authorised installer. To activate this function,
press the summer/winter key (ref. A) for 10 seconds until
both the cooling (ref. C) and heating (ref. B) symbols come
on together. To return to the cooling only or heating only
setting, press and hold the summer/winter key (ref. A) for
10 seconds until the cooling (ref. C) and heating (ref. B)
symbols switch off. Press the key again to select winter
mode. Check the heating symbol is working (ref. B) (on
when set point is higher than ambient temperature, both
are off when the set point is lower. Press the summer/
winter key once to select summer mode. Check the
cooling symbol is working (ref. B) (on when set point is
lower than ambient temperature, both are off when the set
point is higher). This selection is saved even if the power
is turned off.

Rigid or flexible wires with a 0.2 to 1 mm² cross-section
(0.75 mm² if two wires are connected to the same terminal
block) can be inserted in the 4 terminal blocks (ref. A) for
connection of the wall-mounted controller EDA/EDB649
- EWG/EWW649. If the wires have wire end ferrules with
a plastic collar, the maximum cross-section is 0.75 mm².
Strip 8 mm of the wire, then if the wire is rigid, you can
insert it easily whereas, if it is flexible, it is advisable to use
long nose pliers.
Push the wire completely in and check that it is anchored
by pulling it gently.
To disconnect the cables, press the
corresponding white indent (ref. A) with a
screwdriver and remove the conductor.
