GENERAL FEATURES

Unit description

This series of air-water heat pumps satises the heating, coo­ling and domestic hot water production requirements of residen­tial plants of small and medium size.

All the units are suitable for outdoor installation and can be ap­plied to fan coil plants, radiant oor plants and high efciency
radiators plants.

The control system allows to manage not only the refrigerant
circuit but the whole plant with the possibility to choose different
solutions both for the heating and cooling plant and for the do­mestic hot water management. The possibility of solar panels or
other heating sources integration is also available.

The heating function optimizes the ow water temperature ac­cording both to the ambient temperature and to the outdoor tem­perature through climatic curves adaptable to the building featu­res. It’s possible to manage a storage tank and two independent
circuits (a direct one and a mixed one).

The domestic hot water management allows to control the th­ree way valve, the storage tank and the anti-legionella cycles (if
necessary).

The cooling function can be realized through “active cooling”
(refrigerant circuit inversion). When the unit is used in radiant
oor plants, to avoid condensate generation, a room humidity
sensor can be installed.

The internal programmer clock allows to dene different daily
switching programs for heating, cooling and domestic hot water
production.

The refrigerant circuit, contained in a box repaired from the air
ow to simplify the maintenance operations, is equipped with
rotary or scroll compressor (according to the model) mounted
on damper supports, brazed plate heat exchangers, thermosta­tic expansion valve, reverse cycle valve, axial fans with safety
protection grilles, nned coil realized with copper pipes and al­luminium ns. The circuit is protected by high and low pressure
switches and differential pressure switch on the plate heat ex­changer.

The plate heat exchanger and all the hydraulic pipes are ther­mally insulated in order to avoid condensate generation and re­duce thermal losses.

All three-phase power supply units are provided with a phase
sequence and correct sequence controller device.

All the units are supplied with an outdoor temperature sensor in
order to realize the climatic control.

All the units are accurately built and individually tested in the
factory. Only electric and hydraulic connections are required for
installation.

compressor (1) is mounted on damper supports and is protected
against overtemperatures and overcurrents. It is equipped with
an electrcal heater, that is activated when the compressor turns
off, to keep the compressor crankcase oil temperature high
enough to prevent migration of the refrigerant during winter
stops and to evaporate any liquid present in the crankcase, in
order to prevent possible liquid rushes on starting.

The plant side heat exchanger (2) is a brazed stainless steel
plate heat exchanger, properly insulated to avoid condensate
generation and to minimize thermal losses, and protected by
a differential pressure switch that detects whatever water flow
lack.

The source side heat exchanger (3) is a finned coil realized with
grooved copper pipes and aluminium fins with notched profile to
increase the heat exchange coefficient. A tray is obtained in the
basement to collect the condensate generated in heating mode.

The expansion device (4), a thermostatic expansion valve with
external equalizer, allows the unit to adjust itself to the different
operating conditions keeping steady the set superheating.

The refrigerant circuit of each unit contains moreover solid
core hermetic filter dryer (5) to restrain impurity and moisture
residuals that could be present in the circuit, high and low
pressure switches in order to assure the compressor to operate
inside the permitted limits, 4 way reverse cycle valve (6) to
allow operating mode change reversing the refrigerant flow,
liquid receiver (7) to compensate the different refrigerant
charge required in heating and in cooling mode and pressure
connections SAE 5/16” - UNF 1/2” - 20 equipped with pin, gasket
and blind nut, as required for the use of R410A refrigerant (they
allow the complete check of the refrigerant circuit: compressor
inlet pressure, compressor outlet pressure and thermostatic
expansion valve upstream pressure).

The axial fans (8) are contained in a sheet nozzle and are
equipped with a safety grille.

Hydraulic circuit All the pipes are thermally insulated to avoid
condensate generation and minimize thermal losses. The circuit
can be equipped with a standard, a high head or a high efficiency
circulation pump (option). In that case the circuit is also equipped
with expansion vessel and air vents.

Electrical panel It contains all the power, control and security
components necessary to guarantee the unit to work properly.
The unit is managed by a microprocessor controller to which
all the electrical loads and the control devices are connected.
The user interface, to be placed indoor, allows to view and to
modify, if necessary, all the parameters of the unit.

All the units are supplied with an outdoor temperature sensor,
to be installed outside, in order to realize the climatic control.

Description of components

GENERAL FEATURES

The microprocessor controller is able to manage not only the
unit itself but also all that components of the plant which allow to
realize a complete system.
The main functions of the control system are :

- room temperature control according to the outdoor temperatu­re (climatic control)

- domestic hot water production (management of 3 way valve,
storage tank, anti legionella cycles…)

- management of a heating and/or cooling mixed circuit (pump
and 3 way mixing valve)

- management of a heating direct circuit (only pump)

- management of a storage tank for heating and/or cooling

- management of electrical heaters for heating and domestic
hot water (3 steps logic)

- solar panels integration

- room humidity control for cooling with radiant systems

- internal programmer clock (for heating, cooling and domestic
hot water)

- digital input for electrical energy low tariff

- alarm memory management and diagnostic

- compressor and pump operating hour counter

- possibility to manage more units in cascade (maximum 16)

Besides the user interface of the unit to be placed indoor, wi­red or wireless remote thermostats are available which allow to
control all the operating parameters of the unit and to acquire
the temperature in the different zones in order to realize a more
precise and comfortable control.

The unit controller is able to manage a lot of different plant so­lutions enabling automatically the necessary control algorythms
according to the components which have been connected. The
management of such components is possible through additional
expansion modules which communicate with the unit by means
of an internal bus and provide all the inputs and outputs required
to fulfil a complete system.

Room temperature

20.5 C

18:28

FS

The controller is able to manage up to two zones in heating
(one by means of a mixed circuit and the other by means of a
direct circuit) and one zone in cooling (by means of a mixed
circuit).

It’s possible to realize more complex plants connecting to the
heat pump controller further expansion modules in order to
extend without limits the number of zones to be managed.

For each zone the following parameters can be set :

- set point

- daily or weekly operating time table

- climatic control curve

- room control sensor : it can be in common with the other
zones or independent (in that case it’s necessary to install
an additional room thermostat)
