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.

Continuous modulation circuit board for connecting remote thermostat
(only for models ESE645 - ESE648)
LED Indications (Ref. A) (only for models ESE645 - ESE648)
The circuit board for remote control is for all functions of
the fan coil system from the wall-mounted remote control
EDA/EDB649 - EWG/EWW649.
A remote control can be connected to a maximum of
30 fan coils that will be controlled in broadcast mode
(simultaneous commands to all fan coils).
It can be installed on all versions, the board has a green
LED that indicates the operational state and any anomalies.
The main operational parameters, the set point and the
room temperature are transmitted from the wall-mounted
remote control EDA/EDB649 - EWG/EWW649 to all
terminals connected to the network, allowing unified
operation.
Refer to the instructions for this control for use of the fan
coils.
The 10 kΩ water temperature probe positioned in the
device battery regulations the minimum level when heating
(30°C) and the maximum level when cooling (20°C).
Green LED: Indicates that the unit is
operational. Flashing indicates an anomaly. LED off: unit is off or has no power.
Segnalazioni d'errore
Error Display
Communication error. The circuit board expects continuous information exchange on the serial line
with the wall-mounted control EDA/EDB649 - EWG/EWW649. If this exchange is lost for more than
5 minutes, an error warning is displayed and the unit deactivated.
6 flashes + pause
Problem with fan motor (e.g. blockage caused by foreign objects, faulty rotation sensor). 2 flashes + pause
Water temperature probe fault for 2-tube versions (H2).
In this case, ensure that the probe installed is 10 kΩ. 3 flashes + pause
Cold water temperature probe fault for 4-tube versions (H4).(Only for ESE648) positioned on the
main battery. 5 flashes + pause
GRID contact open Continuous rapid
flashing
Water demand detected by probe H2 insufficient (above 20°C when cooling, below 30°C when
heating). Stops the fan until the temperature returns to a suitable level to satisfy the demand*. 1 flashes + pause
Only for board ESE648 (4-tube machines): cold water demand detected by probe H4 insufficient
(above 20°C). Stops the fan until the temperature returns to a suitable level to satisfy the demand*. 4 flashes + pause
* If after having powered the board the water probe is
detected, start-up takes place with the minimum and
maximum water temperature thresholds.
The board also has a function when there is no probe, in
such cases the fan stop thresholds are ignored.

easily, whereas with flexible cable it may be easier to
use a long pointed pair of pliers to insert correctly.

probe which can be remotely installed in one of the fan
coils connected to it) with the possibility to control one
or more units (up to max. 30) fitted with an electronic
controller for remote control ESE645 or ESE648.
- Install the wall-mounted remote control EDA/EDB649
away from doors and/or windows and from heat
sources (radiators, fan coils, hobs, direct sunlight), on
internal walls and around 1.5m from the floor.
The wall-mounted remote control is inside the pre-
assembled package, therefore prior to affixing to the wall,
the two parts should be separated by unhooking the two
protruding teeth on the rear (A).
Use the base of the controller (ref. B in diagram) to trace
the fixing points on to the wall (use two opposing holes).
Then proceed with the following operations:
- drill holes in the wall;
- pass the cables through the window on the base;
- fix the base of the controller to the wall using suitable
screws and wall plugs;
- make the electrical connections then close the
controller taking care not to crush the conducting
wires.

and amber display that contains the AUTO function (step
ventilation adjustment).
The E4T643 thermostat can be set from 5 to 40°C,
has a winter and summer selector and 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). It is suitable
for installing on board and has a 230V output for controlling
a solenoid valve.
It can furthermore control the 4 tube versions, any resistance
outputs or the full flat actuator for mobile grills via a relay fitted
to the board.
The board also has a function when there is no H2 probe,
in such cases the fan stop thresholds are ignored.
