1 SYSTEM DESCRIPTION
OPEN HYBRID MEM-ECO
systems are built-in, “modular” sys-
tems for heating and cooling rooms and for the production of
domestic hot water. They can be "assembled" on the basis of
the system needs requested by the customer.
The basic
OPEN HYBRID MEM-ECO
structure consists of:
– Enclosure frame, fully recessed for outdoors, or in cabinet
for indoors. This must be ordered and installed before the
"components" are requested.
– Basic appliances/components (to be installed inside the
built-in housing structure):
– Hot water storage tank in stainless steel with a capacity
of 150 litres.
– 25, 30 or 35 kW hot water on-demand condensing boiler
– Main electrical panel.
– 8 litre hot water expansion vessel
– Relief valve and pump.
– Pipes for connecting all the appliances which make up
the system.
– A bag containing nuts, bolts and screws, the technical
data plate and the assembly instructions.
– Single column solar panel assembly complete with all the
water circuit elements needed for operating a solar ther-
mal circuit if installed (optional).
– Thermostatic mixer (optional)
– 12 litre solar thermal expansion vessel (optional)
Additional appliances/devices to complete the basic/mini-
mum structure:
–
Sime
SHP M ECO
heat pump to be selected on the basis of
system requirements
– MRM Remote Control to manage the entire system.
In the basic configuration,
OPEN HYBRID MEM-ECO
systems
provide hot water at a maximum delivery temperature of 60°C
and return temperature of 50°C, but they can also be integrat-
ed with the following optional kits:
– High temperature kit: to manage system terminals such as
radiators, fan convectors.
– Solar kit: to use the SIMESOL 182 solar panel to produce
domestic hot water maximising the use of alternative ener-
gy and limiting boiler usage.
m
WARNING
– With this appliance the USE OF THE EXTERNAL
SENSOR IS COMPULSORY for the boiler to work
with a sliding temperature (delivery temperature
varies automatically on the basis of the external
temperature detected), for the activation of the an-
ti-freeze function and to calculate the convenience
of the energy sources.
– Commissioning of the
Open Hybrid MEM-ECO
system
must be carried out by qualified technicians.

1.1 Operation
1.1.1 Domestic hot water
The 150 litre hot water storage tank in STAINLESS STEEL is
made exclusively from renewable sources with the following
priorities:
1
Solar Thermal Energy (if present);
2
Heat pump.
The domestic hot water prepared in the storage tank always
remains in the boiler before being used. The boiler burner is
activated by the MEM only if the inlet temperature does not
reach the setpoint set by the user.
– Weekly programming from the MEM display for the prepa-
ration of the domestic hot water and therefore of the stor-
age tank.
– The solar thermal system (if present) can prepare the 150
litres of hot water in the storage tank at the maximum tem-
perature of 90°C. The actual energy ratio depends on the
solar rays which the solar collector is subject to. The solar
thermal pump is managed by the MEM on the basis of the
storage tank-collector and implements the ANTI-FREEZE
COLLECTOR, COOLING COLLECTOR).
– The heat pump can prepare 150 litres of hot water in the
storage tank up to the maximum temperature of 50°C.
Preparation by the heat pump only occurs in periods in
COMFORT mode. To allow for preparation when also in RE-
DUCED mode, act on the specific parameter.
– The amply dimensioned plate heat exchanger allows the
heat pump to operate with high COP values also for the
preparation of domestic hot water in addition to reduced
restore times. Management by the MEM includes activation
of the heat pump only when the storage tank is almost com-
pletely depleted of hot water in order to reduce the number
of start-ups to a minimum and to allow the heat pump to
operate at low temperatures (high COP).
– The actual preparation temperature of the storage tank by
the heat pump is calculated dynamically by the MEM on the
basis of the efficiency conditions (external temperature +
delivery temperature).
– The MEM manages the heat pump domestic hot water pri-
ority on the basis of some modifiable parameters:
–Priority in the summer (COOLING or DOMESTIC HOT WATER
with maximum time to be set). Default priority COOLING
– Priority in the winter (HEATING or DOMESTIC HOT WATER
with maximum time to be set). Default priority DOMESTIC
HOT WATER for no more than 30 minutes.
– The ANTI-LEGIONELLA function, if enabled, includes prepa-
ration of the storage tank at a temperature of 55°C (main-
tained for approximately 2 hours) once a week for bacteria
sanitisation.
1.1.2 Heating
– The heating request is made by means of the dry contact
(for example, a safety limit microswitch, etc..).
– The medium-low temperature heating circuit can reach a
maximum delivery temperature of 55°C with only the heat
pump operating. It is possible to reach a temperature of
60°C (return 50°C) with the combined heat pump - boiler
operation.
– The 30 litre inertial storage tank acts as a thermal flywheel
(needed by the heat pump) and hydraulic separator allow-
ing operation with any flow rate processed by the system.
Thanks to the specific design, the inertial tank always guar-
antees the best possible working conditions for the heat
pump making it work at the minimum temperature made
available by the system (no mixing of the return water inside
the inertial storage tank).
– The delivery setpoint can be set by the user at a fixed value
or it can be calculated dynamically by the MEM on the basis
of the external temperature and the selected climatic curve.
– System safety thermostat (50°C fixed calibration with the
option of deactivating the parameter) to protect the radiat-
ing system at low temperatures.
– In every operating condition, the MEM control unit calcu-
lates the heat pump COP (external temperature + delivery
temperature) and therefore whether the boiler or the heat
pump is most appropriate and it controls the subsequent
activation. If the most appropriate source is not sufficient to
cover the system needs, the other source can be activated
at the same time for the minimum energy needed to reach
the setpoint (this function can be set by the specific param-
eters). This way AND (simultaneous) operation is possible of
the sources allowing the heat pump to be activated even in
conditions in which it would normally be switched off as the
power output is less than the system requirements.
– The power modulation of the heat pump and the boiler is
always controlled by the MEM at the minimum level neces-
sary to meet the set system setpoint (there is no increase in
the generator setpoint in relation to the system if not nec-
essary).
–The defrost function of the heat pump is controlled by the MEM
eliminating almost all temporary comfort loss and compen-
sating the energy withdrawn from the system or the boiler.
– Using the MEM parameters, it is possible to set gas and
electrical energy costs to allow the dynamic calculation of
the financial advantage of using each individual source. If
this data is not available, the energy convenience will still
be calculated (primary energy equivalence).
– The high efficiency and high flow-head modulating pump
is able to guarantee the necessary flow rate to the system
adjusting the number of revolutions (and therefore the con-
sumption) on the basis of the instantaneous absorbed pow-
er of the system.
– Option of installing a HIGH TEMPERATURE KIT for an addi-
tional heating circuit with delivery temperature up to 80°C.
This circuit is used exclusively by the boiler as the temper-
atures are too high for the heat pump to operate. If the re-
quest is made for the boiler to operate together with the
high and low temperature circuits, the boiler generates with
a high temperature setpoint while the low-temperature cir-
cuit is adjusted by means of a distribution valve before mix-
ing inside the puffer to obtain the set temperature.

8
1.1.3 Cooling
– Setting the summer mode (cooling) from the remote display
or remote contact (option of installing a summer/winter se-
lector for the user's convenience - not supplied).
– The cooling request is made by means of the dry contact (for
example, a safety limit microswitch, etc..).
– Heat pump operation only in cool mode.
– Fixed system setpoint set by the user.
– Humidistat input (dry contact) for a second setpoint which
can be set by the installer for dehumidification (reduction)
or to prevent the formation of condensate in the radiating
system (increase).
– The power modulation of the heat pump is always controlled
by the MEM at the minimum level necessary to meet the set
system setpoint (there is no reduction in the heat pump set-
point in relation to the system if not necessary).
– 30 litre puffer and pipes with insulation present. The install-
er must complete the insulation of the connection points as
indicated in the installation manual.
1.1.4 Anti-freeze function
–Protection activated by the MEM with activation of the pumps,
valves and generators on the basis of the temperatures de-
tected by the sensors (electrical power is required). It is es-
sential that there is a correctly installed external sensor.
1.1.5 Anti-blocking function
– Function controlled by the MEM with the activation of all the
active organs after a period of inactivity to prevent blocking
(electrical power is required).
1.1.6 Photovoltaic function
– Function managed by the MEM to increase the amount of
auto-consumption of the electrical energy produced by a
photovoltaic system if installed.
1.1.7 Automatic filling function
– If system pressure drops with the subsequent intervention
of the low pressure alarm, it is possible to refill simply be
pressing a button on the display.
1.1.8 Automatic degassing function
– Function to be activated by the installer or technical per-
sonnel to allow rapid degassing of the air inside the system
during commissioning
– In any case, the system must be made according to the di-
agrams present in the installation manual and goose-neck
fittings are to be avoided.
– If they cannot be avoided, the installer must ensure that
there are bleed devices in the top sections.
