2. MODULATING TEMPERATURE CONTROLLER KIT
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.
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
which must not be removed.
- 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

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)

M1 DC inverter fan motor
S1 grill safety micro-switch
Y1 water solenoid valve (230V/ 50Hz 1A output
voltage)
L-N electrical power supply 230V/50Hz
BO boiler consent output (free contact max 1A)
CH chiller consent output (free contact max 1A)
CP presence input sensor (if closed, the fan coil unit
is placed in standby)
*If after switching the power on the board detects
the probe, start-up occurs in normal conditions
with the minimum water temperature when
heating (30°C) and maximum when cooling
(20°C).
The board also has a function when there is no
probe, in such cases the fan stop minimum and
maximum 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 board:
- connect the grounding cable to the unit structure (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) *;
N.B.: should the board not be fitted in the factory, the
fan motor must be rotated 180° due to the length of
the standard fan coil cable.
- on the two GRID block terminals (ref. L) there is a
bridge which must not be removed.
- For other versions, remove the bridge and connect the
two terminals originating on the grill safety microswitch;
N.B.: should the two brown terminals on the unit be
too short, replace them with those included in the kit
packaging.
- connect the water probe connector H2 (ref. F) on the
unit.
The water temperature probe controls the temperature
inside the batteries and determines when the fan
starts according to pre-set parameters (minimum
operation in winter and maximum in summer). Check
that they are correctly inserted into the compartment
on the battery.
- make the electrical connections, tidy the cabling;
- 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 on-board controller with speed selector and ON/OFF
key, room thermostat adjustable from 5 to 40°C, winter
summer selector and minimum winter temperature function
(30°C) and maximum summer temperature (20°C) is suitable
for fitting on board the unit and has a 230V - 1A output for
controlling a solenoid valve.
