VERSIONS
Check the table with the available configurations for any inter-

The basic version constists of a cooled-water water chiller.
/HP:
reversible heat pump
Besides the components of the MU ECHOS, the cooling circuit
is equipped with 4-way inversion valve and a second thermo-
static expansion valve. The hydraulic circuit consists of a pres-
sure switch valve, a bypass solenoid valve and a second vane-
operated water flow switch. These components are already
installed on the 6, 8 and 11 sizes and for the other sizes they
are supplied with in the kit). The electrical panel has a digital
input contact for summer/winter switching.
/LE:
motocondensing unit
Motocondensing unit: The unit is designed to operate with an
air-cooled evaporator therefore it does not have a heat exchan-
ger on the user side or a thermostatic valve (can be supplied in
the kit upon requeast). The unit is loaded with nitrogen instead
of refrigerant
/LE /HP
reversible motocondensing unit
The unit is designed to operate with a remote air-cooled eva-
porator/condenser therefore it does not have a heat exchanger
on the user side or a thermostatic valve suited for chiller opera-
tion mode(can be supplied in the kit upon requeast). The unit
has a fluid receiver sized for the split unit supplied by Blue Box
and the thermostatic valve for the heat pump operation mode.
The unit is loaded with nitrogen instead of refrigerant
/LC
motoevaporating unit
The unit has no heat exchanger on the source side in order to
allow connection to a remote air-cooled condenser. The unit is
loaded with nitrogen instead of refrigerant
/LC /HP

mode and no heat exchanger on the source side in order to
allow connection to a remote air-cooled condenser/evaporator.
The unit has a fluid receiver sized for the remote condenser
supplied by Blue Box.
The unit is loaded with nitrogen instead of refrigerant.
/LN
low-noise unit
The sizes 6, 8 and 11 with this outfit require the replacement
of the standard sound absorbing material with a multi-layer
acoustic insulation of high impedance.
The sizes from 16 to 48 require the installation of a sound-
proof cover on the compressor. This outfit can be combined
with all aforementioned versions of the unit
HYDRAULIC SYSTEM OPTIONS
The unit basic version has no circulation device or pump instal-
led (except for the 6, 8 and 11 sizes). All the outfits (except for
LE and LE/HP) can be equipped upon request with one of the
following hydraulic modules:
/ST 1P
Besides the standard components installed, the unit has a
circulation pump. This version is not suitable for the 6, 8 and
11 sizes .
/ST 1PS
Besides the standard components installed, the unit has an
inertial insulated storage tank and a circulation pump. The sizes
6, 8, 11 and from 16 to 48 of the HP version have the safety
valve and the expansion vessel fitted as standard.
This version is standard for the sizes 6, 8 and 11 while for the
other sizes it must be requested when ordering.

“BRINE KIT”ACCESSORY
It is applied if the evaporator output temperature is included
within +3°C and -8°C. It consists in a higher thermal insulation
of the exchanger and piping, a specific calibration of the low
pressure switches and of the anti-freeze alarm, and dimensio-
ning check of the mechanical thermostatic valve.
If it is not included in the set-up, the “Check condensation”
accessory must be added.
ELECTRONIC THERMOSTATIC VALVE
L’utilizzo di questo accessorio è particolarmente indicato sulle
unità che si trovano ad operare in condizioni di carico termico
molto variabile o di modalità di funzionamento variabili, come
nel caso della gestione congiunta di condizionamento e pro-
duzione di acqua ad alta temperatura. L’impiego della valvola
termostatica elettronica infatti permette di:
• massimizzare lo scambio termico all’evaporatore
• minimizzare i tempi di risposta alle variazioni del carico e di
condizioni operative
• ottimizzare la regolazione del surriscaldamento
• garantire la massima efficienza energetica
SELF-ADAPTABLE REGULATION LOGIC
This function allows the unit control to dynamically vary the
outlet water set point according to the stop and functional
cycles of the machine: in practice, by increasing and reducing
the water outlet temperature, the control avoids that compres-
sor start-ups are too close in time, decreasing the number of
peaks and protecting the unit components
REMOTE ON/OFF FROM DIGITAL INPUT
This function is standard on all units and consists in a remote
contact that allows to switch on and off the machine through a
signal that can be taken inside the building by a BMS (Building
Management System) system.

MU ECHOS A
SUMMER/WINTER SELECTION FROM DIGITAL
INPUT
This function is standard on all heat pumps. When the unit is
switched on, a functioning mode must be set, which can be
either the heat pump or the chiller one. Through this remote
contact, the functioning mode can be modified even inside
the building and without a direct access to the microprocessor
control.
FILLING SYSTEM WITH MANOMETER
This accessory allows the automatic load of the hydraulic sys-
tem, the adjustment of the correct working pressure, which
can always be verified by using the manometer, and enables
the continuous maintenance of such pressure, reintegrating
the missing water if necessary.
RS-485 INTERFACE
The growing diffusion of both domotic and BMS (Building
Management System) systems led to the integration of all the
system components under an only supervision. To respond to
this request, the unit can be equipped with a serial board that
allows the correct machine integration in the “building-sys-
tem”, by using MODBUS or CAREL communication protocols..
REMOTE CONTROL USER TERMINAL
Intended for a professional user, it consists in a faithful re-
production of the control panel, from where the unit can be
completely set and all its parameters visualised on the display.
Insertion of passwords, which enable different access levels,
are required to access the parameters.
The type of terminal depends on the control installed on the
unit
USER INTERFACE µAD
By using a simple and intuitive interface, this device allows to
carry out the following main functions:
• Switching on and off the unit
• The unit function mode switch-over from heat pump to
chiller and vice versa
• Enabling the sleep function
• The weekly timer thermostat function with automatic ON/
OFF management of the unit
• Displaying unit functioning conditions
SOFT-STARTER
Blue Box units adopt all the required functioning set-ups and
logics to minimise peak currents. The Soft-Starter accessory
allows a further 40% reduction of normal current peaks,
through an electronic control of the electric motor start-up.
COMPENSATION OF THE SET-POINT according to the external
air temperature
The unit microprocessor control can compensate the set point
in a dynamic way, on variation of the external air temperature.
The compensation can be positive or negative: with positive
compensation, on increase of the air temperature the functio-
ning set also increases. With negative compensation on in-
crease of the air temperature the set decreases. Compensation
can be made either on the summer set point or on the winter
set point (heat pumps).
By default, both summer and winter negative compensation is
set, but this configuration can be modified from the micropro-
cessor keyboard. Unless otherwise specified, default values are
indicated in the graphics below.

Maximum input current
Version ST1P o ST1PS
Maximum absorbed power
Maximum absorbed current
Maximum input current
Main power supply
Standard power supply
Optional power supply
The indicated data is valid for unit with standard power supply
(1)Electrical power that must be supplied by the mains to power the unit.
(2)Internal breakers tripping current. This value is never exceeded and must be used to size the line and its protections (refer to the electric diagram supplied with the unit).
(3)The maximum peak of the current is calculated considering the compressor start and the maximum power absorbed by all the other devices.
The value between parentheses refers to the units equipped with soft-starter (optional).
(4)To be asked for when ordering
The values and images inside the document are indicative and can be modified by the manufacturer without prior notification.
For further information refer to the specific documentation. The reproduction of this material, even partial, is prohibited.
