1. DESCRIPTION OF THE UNIT
are protected against frost on the inside by an electric heater
with thermostat, while, when the unit is operating, protection is
ensured by a water differential pressure switch.
High efficiency range
The i-NRG heat pump features high seasonal efficiency in both
heating and cooling mode, using DC inverter technology to
modulate compressor operation and deliver the exact amount of
energy based on the actual needs of the building.
This excellent result has been achieved by carefully sizing all
the components. Special attention has been paid to all heat
exchange surfaces and the fans.
The use of newly designed condensing coils, with larger surfaces and special layout, new asymmetrical evaporators with
better and more efficient refrigerant distribution, both in the liquid and gas phase, and high efficiency fans are some of the
important innovations included with this product.
Careful sizing of the systems this series of units are used with
can mean significant savings in energy consumed and consequently a major reduction in running costs.
Domestic hot water production is provided by a specific heat
exchanger with total or partial heat recovery, and is stored in the
domestic hot water storage tank.
Domestic hot water heat exchanger
Braze-welded AISI 316 steel plate heat exchanger with high efficiency and low pressure drop, can operate either with total heat
recovery or as a desuperheater. The heat exchangers are lined
on the outside with anti-condensate closed-cell neoprene lagging. When the unit is not operating, these are protected
against formation of ice on the inside by an electric heater with
thermostat.
Source-side heat exchanger
Finned coil heat exchanger made from copper tubes and aluminium fins, spaced apart so as to guarantee maximum heat
exchange efficiency
Fans
Axial-flow fans with IP 54 index of protection, external impeller,
with pressed plate blades, housed in aerodynamic tubes with
accident prevention grill. EC motor with low power consumption,
DC power supply, with built-in thermal protector. Fans with continuous speed control by pressure transducer.
Smart Defrost (Climaveneta patent)
The heat pumps come with an innovative and patented selfadaptive defrost system that optimises defrost times, improving
overall unit efficiency.
The strength of this new logic is the ability to automatically
adjust parameters used by the algorithms in each cycle, based
on the outside conditions.
Controlling the evaporation pressure, outside air temperature
and defrost time, give an excellent estimate of ice on the coil,
thus guaranteeing an effective and efficient defrost cycle.

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.
Moreover, the controller modulates fan operation for optimum
condensation or evaporation, depending on the operating
mode, allowing domestic hot water production even in summer
with outside temperatures up to 45°C, and reducing noise at
night.
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
HIGH EFFICIENCY AND REDUCED CONSUMPTION
The i-NRG reverse-cycle air-to-water heat pump is fitted with
DC inverter-driven compressor and EC fan with low energy consumption.
Inverter technology continuously controls compressor speed to
ensure perfect adaptation to system load, modulating the heating or cooling capacity delivered and consequently reducing
power consumption and achieving the highest seasonal coefficients currently available on the market.
The seasonal coefficient of performance faithfully reflects the
advantages in energy and economic terms of using the heat
pump all year around, being the ratio between energy delivered
and power consumed. In terms of improving performance and
reducing power consumption, the electronic thermostatic valve
is an important component that maximises system efficiency.
Quick and effective adaptation by the electronic thermostatic
valve to variations in load allows the compressor to always work
at optimum efficiency, as well as extending compressor life.
This unit completely incorporates the full inverter concept, all
components are designed for maximum efficiency and maximum
savings in running costs. The system and domestic hot water
pumps also have EC motors, with low power consumption,
Class A energy rating, for sustainable energy usage.
OPERATING PRINCIPLE
i-NRG is the new generation heat pump that can work all year
round, in any operating mode, both single cycle (cooling, heating, domestic hot water) and combined cycle (domestic hot
water together with cooling).
COOLING
The heat pump cools the water in the system circuit, which
absorbs heat from the rooms, thus cooling them, via the system
terminals (underfloor, fan coils, radiators).
The system pump runs until the set point is reached, and then
works intermittently so as to measure the water temperature.

COOLING with PARTIAL heat recovery
When the domestic hot water set point has been reached and
the compressor is on to cool the system water, the pump on the
domestic hot water heat exchanger is activated intermittently,
thus achieving partial heat recovery.
The heat is transferred to the domestic hot water storage tank,
allowing the water temperature to rise above the set point.
The temperature reached varies depending on how long the
compressor operates in order to meet system demand.
If domestic hot water consumption increases significantly, the
unit will work in total heat recovery mode, using all of the unit’s
heating capacity to heat the domestic hot water.

COOLING WITH TOTAL HEAT RECOVERY
In cooling operation, whenever a fluid is cooled (water, in
hydronic systems), heat needs to be transferred to another fluid,
in this case outside air.
It is possible to avoid wasting this heat and recover it so as to
heat the domestic hot water for free.
In total heat recovery mode, the unit can meet demand for
chilled water to the system and hot water to the DHW storage
tank, both at the same time.
The heat transferred to the domestic hot water is completely
free, as it would normally be wasted by discharging it into the
outside environment.

DOMESTIC HOT WATER ONLY
The unit operates in heat pump mode to heat the water in the
domestic hot water storage tank.
This operating mode is available both in winter and summer,
even with outside temperatures up to +45°C (see the operating
limits).
In “domestic hot water only” mode, the unit’s heating capacity
goes completely to heating water in the domestic hot water storage tank.

The heat pump heats the water in the system circuit, which in
turn heats the rooms via the system terminals (underfloor, fan
coils, radiators).

works intermittently so as to measure the water temperature.

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”.
Up to four operating curves can be selected, depending on the
pressure drop in the system, so as to optimise pump operation
and reduce power consumption.
The pumps are class A with EC motors.

FAN SPEED CONTROL
To enable the unit to function correctly at different outside temperatures, a microprocessor with pressure reading via pressure
transducer controls fan rotation speed. This allows the
exchange of heat to be increased and/or decreased, maintaining condensing or evaporation pressures essentially constant.

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.

Bivalent operation
In the case of bivalent operation the heat pump meets the
needs of the building down to a certain outside temperature,
called the bivalence point.
Below the bivalence point the heat pump switches off and only
the auxiliary source (e.g. boiler) provides heat for the building.
This solution is ideal for traditional systems and renovations.

Monovalent operation
For monovalent operation, the heat pump has to meet the entire

There may be excessive heating capacity of the heat pump
above all when the outside air temperature is above zero, as
well as high power consumption.
Make sure the home’s energy meter is correctly sized.

All-electric operation
In all-electric operation the heat pump is integrated with an
electric heater to meet the entire demand of the building.
The electric heater is activated below certain outside temperatures so as to satisfy demand in the building that the heat pump
cannot manage on its own.
Considering the reduced number of hours of heat pump operation at low outside temperatures during the winter period, operation of the supplementary heater will also be reduced, and
consequently power consumption will be negligible.
Therefore the system’s seasonal energy efficiency remains
unchanged.
This solution is suggested for new homes and lower investments than monovalent heat pumps.

NadiSystem manages different temperature levels based on the
terminal units used.
The heat pump directly produces water at the right temperature
for the system terminals connected to the high temperature circuits (e.g. fan coils, radiators, towel rails in bathrooms), while
low temperature radiant panels are controlled by the mixing
valves according to the specific compensation curves.

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 activation of the
electric heater used to protect 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.
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
The system and domestic hot water pumps are activated
according to the outside air temperature to prevent ice forming
in the pipes.
The pump is activated if the outside air temperature is less than
4°C and deactivated when it rises back over 5°C
FROST PROTECTION BASED ON INSIDE AIR TEMPERATURE
The heat pump and/or supplementary heat sources (outlet
heater or boiler) are activated if the inside temperature falls
below 14°C, to prevent the pipes inside the home from freezing.
ALARM SIGNALS
Correct unit operation and any alarms are displayed on the
room thermostat, the latter by the
symbol.
The diagnostics functions include complete alarm management,
with an alarm log (via service keypad) for more detailed analysis of unit behaviour.

RDK RECTANGULAR DUCTING KIT
Straight duct
The i-NRG heat pump can be installed internally, with suitable
ducting for air intake and outlet.
Climaveneta has made a suitably-sized rectangular ducting kit
to guarantee correct heat pump operation.
The RDK kit is supplied with components to be assembled on
site to avoid excessively large packages for shipping and storage.
The ducts are made from polyurethane foam sandwich panels
(water-blown, without using greenhouse gases), covered by
aluminium sheet for exceptional thermal insulation, rigidity and
lightness, low pressure drop and a pleasant exterior surface finish of the aluminium sheet, which can be painted in different
colours or with scratch finish or other wall coatings (standard
blue finish).
Corner
The sections of ducting are assembled using a bayonet coupling system, for straight sections, and ‘T’ brackets for corners.
The kit comes with one straight section, 1200 mm long, and a corner piece. These can be used separately to achieve the configuration
shown in the figure, thus guaranteeing the specified clearances.

The length of the straight section of ducting can be adjusted
using a simple cutter, cutting the panels to the desired length
and applying the special ‘F’ bayonet at the ends of the duct.
If heat pump installation requires ducting of both the intake and
outlet air at 90°, two RDK kits will need to be ordered.
The kit is also supplied with a grill that provides a decorative finish and protects the duct against the elements, as well as stopping small animals and leaves from entering.
The grill supplied has been specially developed for use with
heat pumps to achieve lower pressure drop than traditional
grills available on the market.

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.
Wall-mounted installation using the fastening brackets.

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.

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.

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-EM1 EXPANSION MODULE FOR SYSTEM CONFIGURATION
Dimensions - N-EM1 expansion module
300
The NADISYSTEM control system for residential applications
gives high operating flexibility, activating zone pumps and
valves depending on the set room temperature, and controlling
mixing valves to ensure the correct water temperature in radiant
systems according to the climate conditions set for each circuit.
With NADISYSTEM there up to 15 different types of system
pre-configurations for quick and easy installation, and up to 5
remote keypads for controlling thermal load in likewise zones.

The N-EM1 expansion module is used to connect the secondary circuit components and corresponding zone thermostats
depending on the selected configuration.
Up to 3 expansion modules can be used to create more complex systems.
The meaning of the terminals may change based on the selected configuration, the connections are shown on the instruction
sheet provided with the expansion module.

N-THC ROOM TIMER THERMOSTAT
The temperature and humidity settings are simple and intuitive
using the knob on the front, while the operating mode and time
bands can be selected using the 4 buttons.
The N-THC thermostat is fitted as standard with temperature
and humidity probe for correct control of the temperaturehumidity conditions inside the room.
By using the N-THC thermostat in the system, NadiSystem can
control 5 different zones, managing temperature, humidity and
time bands independently.
The simple and functional backlit display allows rapid viewing of
the settings and environmental conditions.
The main settings are:
- Room temperature and humidity setting (temperature and
humidity probe supplied as standard)
- Operating mode setting: heating, cooling, automatic mode
changeover
- Enable domestic hot water production
- Served zone on/off
- Program time bands
- Wall-mounted installation (maximum distance 500 metres)

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.

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 25 metres due to the
maximum vessel pre-charge pressure of 3 bars.
Make sure that the system terminal at the lowest point H1 can
withstand the pressure of the water column at that point.
