Assembly, set-up and connection of on-board control panels
010 LCD 2T, MB 010 2T, 010 LCD 4T, MB 010 4T
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
twoterminalsoriginatingonthegrillsafetymicroswitch*;
- connect the water probe to the H2 connector on the
device.

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
heatingorcoolingautomatically,excludingnormalmanual
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 1.5 mm² cross-section
(0.75 mm² if two wires are connected to the same
terminal block) can be inserted in the 4 spring-loaded
terminal blocks (ref. A) for connection of the wall-mounted
controller WALL LCD. 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.

The wall-mounted remote control WALL LCD is an
electronic thermostat (fitted with an optional temperature
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 MB 010 2T or MB 010 4T.
- Install the wall-mounted remote control WALL LCD
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.

Rigid or flexible wires with a 0.2 to 1.5 mm² cross-section
can be inserted in the spring-loaded terminal blocks for
the serial connection. If the wires have wire end ferrules
with a plastic collar, the maximum cross-section reduced
to 0.75 mm².
For correct and safe connection, carry out the following
operations:
- Strip back the wires by 8mm as shown below;
- if the cable is rigid the end of the wire can be inserted
easily, whereas with flexible cable it may be easier to
use a long pointed pair of pliers to insert correctly.
- 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. C) with a screwdriver and remove
the conductor.

electronics for remote control MB 010 2T or MB 010 4T
using a suitable two-core cable for serial connections RS485
keeping the power supply cables separate.
- Chase out the wall in order to minimise the length of
the leads;
- complete the line with the supplied 120 Ω heating
element;
- do not make "star" connections;
- The RS485 cable connection is polarised, respect the
"A" and "B" indications on every periphery connected
(for connecting, it is preferable to use a shielded two-
core cable with a minimum thickness of 0.35 mm2);
- connect the + and - power terminals on the wall
mounted terminal block, 5V DC, to one of the boards
MB 010 2T or MB 010 4T, respecting polarity.

When fitted on board the machine it allows for managing the
motor,with modulated speed; motorregulation canbemade
using an analogue 0-10V DC input with 25 kΩ impedance.
For board MB 010 E control outputs these impedance values
must be considered, especially when controlling more than
one unit in parallel.
It has a 230 V output to pilot the solenoid valve.
Slide the blanking 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;

- fix it with the two fixing screws (ref. E);
- connect the grounding cable to the unit structure using
the fixing screws (the minimum force that must be
applied for tightening screws must be around 2N);
- on the two GRID block terminals (ref. I) there is a bridge
that allows SLI and RSI versions to work without a
microswitch.
- For other versions, remove the bridge and connect the

The 10V input, if the S1 input which the grill safety micro
switch is connected to is closed, activates solenoid valve Y1
and regulations fan revolutions.
The speed "ramp" provides for linear regulation from the
minimum value (400 rpm) to the maximum value (1,400 rpm)
for voltage values ≥ 1.1V÷10 V DC.
The motor is off when values are lower than 1V DC.
The Y1 solenoid valve is activated for power values > 1V
DC and switches off then the power drops below 0.9V
DC.
