1. DESCRIPTION OF THE UNIT
Horizontal systems can be made by excavating a field where
the plastic pipes will be laid to a depth of around 1-1.5 metres.
Excavation is however costly due to the considerable amount of
soil handled. To reduce costs, rather than excavating the loop
field, trenches can be dug for laying the heat exchange pipes.
In this case, the geothermal loop will be long and narrow.
Currently the most widespread trench systems are slinky loops,
either 2-pipe or 4-pipe circuits, laid at a depth of around 2.5-3
metres. In this case, as the loop is laid near the surface, PE 80
pipes can be used, diameter DN25 or DN32.
The amount of heat that can be drawn using these types of
solutions ranges from 10 to 15 W/m2, and even higher if there
is surface water.
These values are however also affected by variations in air temperature. On average, the geothermal field should be two to
three times larger than the surface area being heated.
Brine-to-Water heat pump
The MTD heat pumps, optimised for geothermal systems, are
reverse-cycle units that operate in heating, cooling and domestic hot water production modes, using a three way valve (accessory) installed outside of the unit.
The MTD heat pumps can be combined with traditional or radiant systems.
The latter, by working at lower water temperatures, ensure higher overall efficiency and are a very popular solution for new low
energy consumption constructions and systems that exploit
renewable energy sources.
Installation is very simple: integration of the hydronic unit on the
system and source circuits means the unit only needs to be
connected to hydronic system and power supply before starting
operation.
Ground source solutions
Ground source heat pumps exploit the energy accumulated by
the ground, a vast source of heat.
The temperature just a few metres underneath the surface
remains constant throughout the year, without the same fluctuations as air temperature.
This means heat can be drawn from the ground in winter so as
to supply a heating system at an efficiency of around 400% or
higher, or give heat back in summer for cooling, maintaining
high efficiency that remains constant all year round.
The same principle can be exploited for domestic hot water production.
Heat is exchanged with the ground via polyethylene pipes that
are either laid horizontally in the ground a few metres under the
surface, or vertically if there is limited space around the building.
This is a closed loop with heat carrier fluid made up of water
and glycol, to prevent the liquid from freezing.
COMPOSITION OF STANDARD UNIT
Structure
Load-bearing base and structure made from suitably thick hot
galvanised steel plate. All parts painted with polyester power
coat.
Panelling
External casing made from suitably thick hot galvanised steel
plate, painted with polyester power coat, designed to allow total
access to inside components. All the panels are covered with
high density soundproofing material. Soundproof panelling made
from special open-cell cone-shaped sandwich panels on the outside with filler material on the inside, total thickness 35 mm.
Compressors
Hermetic rotary scroll compressors, complete with sump heater,
electronic thermal overload protection with centralised manual
reset, and two-pole electric motor.
High density rubber soundproof covering.
Vertical loop
A vertical geothermal loop allows the heat pump to draw energy
from a source at a virtually constant temperature all year round,
with considerable benefits in terms of reducing running costs.
This solution requires a small piece of land.
The yield per linear metre of loop in the ground is 50 W/m; this
value is used as the reference for standard ground, as
described in standard VDI4640. A geologist should always be
contacted to verify ground conditions.
Drilling depth is usually around 100 metres (this keeps pumping
power down, increasing system efficiency, while deeper bore
holes depend on the equipment available locally).
The loops used are double U-bend pipes, PE 100, diameter
DN25, DN32 (most common) and DN40.
Depending on heating or cooling capacity required and capacity
of the ground, a series of geothermal loops may be used,
always leaving a space of 8-10 metres between loops to avoid
thermal interference.
The heat yield of the loop and good operation significantly
depend on the type of grout used.
Once the PE pipe has been placed in the bore hole, the hole
must be filled from the bottom up using a product that guarantees high thermal conductivity and low hydraulic conductivity.
Grout generally consists of mixes of cement and bentonite,
where necessary added with silica or quartz sand to increase
thermal conductivity, or commercially-available premixed products. This also prevents any interference with underground
aquifers that the loop/loops may cross.
Utility-side and Source-side heat exchanger
Braze welded AISI 316 steel plate heat exchanger. The heat
exchangers are lined on the outside with a layer of closed-cell
neoprene to prevent condensation. When the unit is not operating, the heat exchangers are protected against no flow conditions by a water differential pressure switch. The unit is also
ready to operate using non-freezing mixes and with an electric
heater for frost protection.

2. ELECTRONIC CONTROLLER
The NADISYSTEM electronic controller is based on an innovative and efficient approach to building air-conditioning.
Energy is only consumed when necessary and the energy
sources are used based on availability, efficiency and cost, giving priority to renewable sources, where available.
The first significant advantage of introducing a single integrated
control system is optimisation of energy savings through coordination between the different system components, eliminating
inefficiencies in communication, simplifying installation and
reducing the number of controllers.
NADISYSTEM ensures dynamic control of water outlet temperature according to real needs in the building and the outside air
temperature, optimising comfort and reducing wasted energy.
The remote keypad supplied with the unit can be used to freely
set the room temperature, humidity, operating mode, domestic
hot water production and operating times for each zone.
The NADISYSTEM control system for residential applications
gives high operating flexibility by controlling the secondary circuits, that is, activating zone pumps and valves depending on
the room temperature set on the remote keypad, and by controlling mixing valves to ensure the correct water temperature in
radiant systems according to the climate conditions set for each
circuit.
There are 15 different types of pre-configured system for quick
and easy installation, with the possibility to manage up to 5
remote keypads for controlling thermal load in likewise zones.
The advanced PRANA controller also allows integration of solar
panels for the domestic hot water production, giving priority to
direct solar energy, if available, and increasing the use of
renewable sources while also managing traditional sources,
such as electric heaters or boilers.
The controller can manage up to four 4 heat pumps connected
in cascade to increase capacity in applications with multiple
occupied areas, such as hotels, schools, apartment blocks,
offices and shopping centres.
The units are managed in master-slave mode, with the master
unit responsible for processing the information and sending it to
the slave units.
This ensures fine control over the capacity delivered, without
decreasing performance, and more precise system sizing.
NADISYSTEM can determine how many cascaded units are
needed to guarantee domestic hot water production, all or just
one, according to requirements.
The controller also balances compressor operating hours based
on time logic, activating the units in rotation, and where necessary excluding any units that are momentarily out of service,
without interrupting operation of the cascade as a whole.
NADISYSTEM also allows easy service, being interfaceable to
supervision systems for remote maintenance by specialist technicians, as well as remote control of certain functions, such as:

3. OPERATING CHARACTERISTICS
TEMPERATURE CONTROL
The water temperature delivered to the heating and cooling circuit is calculated by the controller and depends on the selected
cooling and heating compensation curve.
A building’s thermal requirements do not remain constant
throughout the day or the year, but rather increase or decrease
based on the outside air temperature.
It’s therefore a waste of energy to keep the water at a constant
temperature. Delivering water at different temperatures to the
terminals based on the outside air temperature achieves high
seasonal efficiency ratios and brings considerable savings in
running costs.
The compensation curve in heating and cooling mode can be
adjusted to allow correct heat pump operation according to the
system (radiant panels, radiators, fan coils).
Example: Selecting heating curve 1.4 with an outside air temperature of -5°C gives a water temperature of +55°C.
Dedicated compensation curves can be set for each zone,
depending on the type of terminal unit, or alternatively a fixed
point temperature can be selected.
A function called “room temperature influence” is available to
quickly adapt the water temperature by modifying the compensation curve when the indoor conditions change, for example
when there are more occupants in the room.
This function is only available in heating mode.
In cooling operation during summer, the controller calculates
the dew point using temperature and humidity probe on the
remote terminal, which determines an increase in the water
temperature to deliver to the radiant system and activation of
the dehumidifier (one dehumidifier contact only for all zones).

SYSTEM PUMP OPERATION
When reaching the system water temperature set point, the
compressor stops and the system pump is activated periodically, so as to minimise energy consumption and ensure correct
measurement of the water temperature.
The pump on and off times can be set using a parameter,
according to the type of system.
In systems with fan coils, the time between one sniffing cycle
and the next should be reduced in order to avoid excessive
cooling of the water, in heating operation, and if and if the system water content is equal to the minimum value shown in the
paragraph on “Minimum and maximum system water content”.

SOURCE PUMP OPERATION
The BWR unit’s electronics can manage condenser or evaporator operation precisely and reliably, controlling the flow of water
through the heat exchanger by modulating operation of the
ground source pump.
The condensing/evaporating pressure is read by a dedicated
sensor installed on the unit; the electrical signal is then sent to
the electronic controller that, based on the configuration parameters, modulates operation of the ground source pump by
adjusting power supply voltage.
DOMESTIC HOT WATER PRODUCTION
The controller manages domestic hot water production using a
3-way valve installed outside of the unit, deviating the flow of
hot water to the DHW storage tank, which must be suitably
sized according to the type of usage.
Production is enabled when the water temperature inside the
DHW storage tank (probe BT8) is less than the DHW set point.
The production of domestic hot water is guaranteed in both
summer and winter, according to the operating limits shown in
this manual.
If heat pump operation is expected outside of the limits, consider using a supplementary source of heat, managed directly by
the controller.
An electric heater should be installed inside the DHW storage
tank to ensure the temperature does not fall below 10°C in the
event of extended periods of heat pump inactivity (standby).
LEGIONELLA PREVENTION FUNCTION
The Legionella prevention function ensures the elimination of
the Legionella bacteria that reside in domestic water storage
tanks.
The temperature and duration of the Legionella prevention
cycles to eliminate bacteria are typically:
• 2 minutes > 70°C
• 4 minutes > 65°C
• 60 minutes > 60°C
The Legionella prevention cycles are managed directly by the
controller, enabling the heater in the domestic hot water storage
tank domestic, with the possibility to set the duration, temperature, day and time.
AUXILIARY RESOURCES
The controller can manage devices outside of the heat pump,
such as electric heaters or boilers.
The auxiliary device can be used to replace or supplement heat
pump operation, as selected by parameter.
In the first case, the external device is activated to replace the
heat pump during operation outside of the limits shown in paragraph 6, “Operating limits”, or alternatively if the compressor
shuts down due to a fault.
In supplementary operation, the external device is activated at
the same time as the compressor so as to satisfy the building’s
thermal demand, based on the trend in water temperature, as
shown in the graph.

If the radiant system also needs to meet cooling demand,
humidity control is guaranteed by activating the dehumidifier
contact, while calculation of the dew point, measured by the NTHC controller, ensures the correct water outlet temperature
defined by the cooling compensation curve, thus avoiding formation of condensate on the floor.
Remember to suitably insulate the pipes in contact with the air,
if air-conditioning in used inn summer.

FROST PROTECTION
The frost protection function is active even when the heat pump
is OFF.
DOMESTIC HOT WATER FROST PROTECTION STORAGE
The domestic hot water frost protection function is only active if
an auxiliary resource is installed for the domestic hot water storage tank.
The additional heater is activated if the water temperature,
measured by sensor BT8, is less than +5°C, and is deactivated
at +8°C.
PRIMARY CIRCUIT FROST PROTECTION SYSTEM
The frost protection function is guaranteed by activating the
electric heater on the heat exchanger and the system pump.
The pump and the electric heater are activated if the water temperature (measured by the probe at the heat exchanger outlet)
is less than 4.5°C and deactivated when the water temperature
reaches +7°C.
Frost protection active for the system and source heat exchanger. Frost protection on the source circuit is activated when the
water temperature is less than -4.5°C.
SECONDARY CIRCUIT FROST PROTECTION SYSTEM
The pumps on the system’s secondary circuit are activated
together with the primary pump, according to the criterion
described in the previous paragraph.
FROST PROTECTION BASED ON OUTSIDE AIR TEMPERATURE

OUTLET ELECTRIC HEATER
The outlet electric heaters are available with power ratings of 3
kW single-phase and 3, 6 and 9 kW three-phase.
Used on the system outlet, these guarantee the heating
demand of the building at low outside temperatures by supplementing the heating capacity of the heat pump.
The electric heaters are deactivated as soon as the heat pump
alone can meet heating demand.
Considering that normally the heat pump operates only a short
time at low outside temperatures, operation of the supplementary heater is also reduced and consequently power consumption is negligible.
Therefore, the system’s seasonal efficiency ratio remains
unchanged.

TPS STORAGE TANKS AND DOMH2O INSTANT
DOMESTIC HOT WATER PRODUCTION KIT
Storage tank model available
TPS300
TPS500
TPS1000
The TPS storage tank is used to store water heated by a heat
pump, and allow further supplementary heat from the solar
heating coils fitted inside. In addition, tank connections are also
available for other sources of heating, for example gas- or
wood-fired appliances. Two electric heaters can be installed
using the 2” fittings provided.
Domestic hot water production is guaranteed by the
DOMH2O15 and DOMOH2O24 instant kits combined with the
storage tanks.
The instant domestic hot water production kit draws energy
from the storage tank and via heat exchange with the plate heat
exchanger ensures the correct domestic hot water temperature,
controlled by modulation of the primary circuit pump.
The control unit with graphic display allows the user to monitor
operation, as well as set the set point and operating parameters.

Technical specifications
TPS storage tanks
The storage tanks are made from carbon steel plate welded
using the best technology and undergo strict water pressure
tests (9 bars, allowing an operating pressure of 6 bars).
Being a container of hot and cold water, this product does not
require internal treatment, while the outside is coated with rustproof paint.
The tanks are protected on the outside with a closed cell elastomeric foam lining, 70 mm thick, with soft blue PVC exterior finish.
DOMH2O instant domestic hot water production kit
The instant domestic hot water production kit features the following components:
- AISI 316 stainless steel plate heat exchanger, insulated
- Circulating pump with low power consumption and electronic
speed control
- Control unit with graphic display indicating the temperature
and heat delivered
- Insulated copper pipes and connectors
- Sheet metal structure and thermoformed RAL panels, wallmounted installation.

BWR_MTD2_0011_0121_201110_EN
HFC 410A
BWR MTD2
The control unit adjusts the speed of the primary circuit pump to
maintain the set domestic hot water temperature, adjustable
from 30°C to 65°C. If the domestic hot water temperature leaving the heat exchanger reaches Tmax (between 60°C and
75°C) the primary circuit pump is switched off.
When the temperature falls below the threshold (Tmax) the
pump is started again.
For systems with supplementary solar heating, the primary
circuit temperature may exceed the maximum limit of 65°C
and pump speed modulation may not guarantee the DHW
set point.
In this case, a thermostatic valve should be used at the
instant domestic hot water production kit outlet to avoid
excessive domestic hot water temperatures.
The DHW recirculating pump can be managed (maximum power 185 W) by setting the water temperature in the recirculation
circuit.
When the temperature falls below the set point the recirculating
pump is activated, and vice-versa.
In addition, on and off times can be set for the recirculation circuit and a custom program created for each day of the week.
Selection guide
To choose the best system made up of storage tank and external instant hot water production unit, the following three parameters need to be verified:
1. Tank volume is sufficient to produce the DHW required by
the system.
2. Instant flow-rate of the external unit is higher than peak delivery flow-rate.
3. Storage tank volume is higher than the minimum recommended volume for correct heat pump operation (based on
heat output).
This condition is normally verified as the volume is quite low.
2. Instant DHW production
The amount of domestic hot water required at the points of
delivery must be less than the amount produced by the unit.
The graphs on the previous pages illustrate the amount of water
produced by the units as the primary circuit temperature changes.
3. Thermal inertia
The storage tank, as well as accumulating energy to be used
when necessary, also acts as a buffer for the primary source of
energy, reducing the number of starts and stops.
The volume of the storage tank must therefore be greater than
the value recommended by the manufacturer of the primary
source (heat pump or other appliance).
1. Storage tank volume
Tank volume and the characteristics of the primary source (heat
output and outlet temperature) are the parameters that determine the amount of water that can be delivered in a certain unit
of time. The following equation can be used to size the tank in
terms of volume.
V= [Wf*(Tout-Tin)/(T0-Tf)] - [(P*tm*1000)/(Cp*(T0-Tf)]

N-CM CASCADE MANAGEMENT KEYPAD
The N-CM keypad allows cascaded connection of up to 4 heat
pumps to increase capacity delivered in applications with multiple occupied areas, such as hotels, schools, apartment blocks,
offices and shopping centres.
The units are managed in master-slave mode, with the master
unit responsible for processing the information and sending it to
the slave units.
This ensures fine control over the capacity delivered, without
decreasing performance, and more precise system sizing.
NADISYSTEM can determine how many cascaded units are
needed to guarantee domestic hot water production, all or just
one, according to requirements.
The controller also balances compressor operating hours based
on time logic, activating the units in rotation, and where necessary excluding any units that are momentarily out of service,
without interrupting operation of the cascade as a whole.
If the malfunctioning unit is the master, the operating parameters are transferred to another unit in the cascade, thus restoring partial operation.
The N-CM keypad can also display the operation of each heat
pump connected to the cascade and the N-THC room terminals
assigned to the zone in question, up to a maximum of 5 zones.

N-RS RS485 SERIAL CARD
The N-RS is an optional card for directly interfacing the heat
pumps to an RS485 network.
The card guarantees opto-isolation of the controller from the
RS485 serial network.
The maximum baud rate available is 19200 baud.
The optional card is fitted in the comb connector on the unit’s
board.

Tab. 4
The data shown in the table refer to heat pumps with a 2-litre expansion vessel and a minimum water temperature of 4°C
Expansion vessel calibration
The expansion vessels are pre-charged to a standard pressure
of 1 bar.
The pre-charge pressure is chosen depending on the maximum
difference in height between the system terminal and the heat
pump, as shown in the figure.
H
The maximum height must not exceed 55 metres due to the
maximum vessel pre-charge pressure of 6 bars.
Make sure that the system terminal at the lowest point H1 can
withstand the pressure of the water column at that point.

Give the typical operating conditions of units designed for outdoor installation, which can be associated (according to reference document IEC 60721) to the following classes:
- climatic conditions class 4K4H: air temperature range from -20 up to 55°C (*), relative humidity range from 4 up to 100%, with possible
precipitations, at air pressure from 70 and 106 kPa and a maximum solar radiation of 1120 W/m2
- special climatic conditions negligible
- biological conditions class 4B1 and 4C2: locations in a generic urban area
- mechanically active substances class 4S2: locations in areas with sand or dust representative of urban areas
- mechanical conditions class 4M1: locations protected from significant vibrations or shocks
The required protection level for safe operation, according to reference document IEC 60529, is IP43XW (protection against access, to
the most critical unit's parts, of external devices with diameter larger than 1 mm and rain).
The unit can be considered IP44XW protected, i.e. protected against access of external devices (with diameter larger than 1 mm) and
water in general.
