REFRIGERANT GAS
This unit contains fluoride gases with
greenhouse effect covered by the Kyoto
Protocol. Maintenance and disposal
must only be performed by qualified
staff, in compliance with standards in
force.
1. DESCRIPTION OF THE UNIT
Multipurpose OUTDOOR units for 2 or 4 pipe systems,
especially designed for simultaneous production of
cold and hot water and fully independent.
AVAILABLE VERSIONS
1.1. FOR 2PIPE SYSTEMS
The multipurpose 2-pipe units have been made
for applications with 2 pipe terminals, e.g. hotels,
where there is a cold/hot water and DHW demand
throughout the year.
The operating modes are:
SUMMER FUNCTIONING
1. Cold water production to system.
2. Production of domestic hot water with use of
total recovery (NO ANTI-LEGIONELLA CYCLE).
WINTER FUNCTIONING
3. Heat pump supplying the system.
4. Service heat pump of DHW.
1.2. FOR 4PIPE SYSTEMS
The multipurpose 4-pipe units have been made for
applications with 4 pipe terminals, e.g. shopping
centres, offices or facilities with large windows where
there can be the simultaneous demand for hot and
cold water with a system which does not require
season changeover and therefore is a valid alternative
to traditional systems based on the chiller-boiler
combination.
The microprocessor control logic ensures perfectly
satisfying heat and cooling loads.
The operating modes are:
PRODUCTION OF COOLED WATER ONLY
The multipurpose unit acts as a classical refrigerator:
cool water to the system and condensation heat
disposal outside through finned coils.
PRODUCTION OF HOT WATER ONLY
The multipurpose unit acts as a heat pump, exploiting
the heat of the outside air, through the finned coil
(evaporator) it raises the temperature of the water to
be sent to the system through a plate heat exchanger
(condenser). The main difference from traditional
cycle reverse heat pumps is that the heated water is
produced in different heat exchanger from the one
used to produce cold water. This separates the two
hot-cold sections required for 4-pipe systems.
COMBINED PRODUCTION
If the utility requires simultaneous hot and cold
water, the unit acts as a water heat pump, controlling
condensation and evaporation on two distinct plate
heat exchangers associated to circulation of cold and
hot water in the system.
It automatically changes from one configuration to
another (managed by on-board microprocessor) to
optimise the spent energy depending on the demand
by the utility.
Maximum reliability
Multi-circuit unit designed to provide the maximum
efficiency both with full load and partial loads,
guaranteeing operating continuity should one of the
circuits stop to facilitate maintenance.
Having several compressors and circuits ensures
control of more steps of power yielded in both modes.
Built-in hydronic kit
Encloses the main hydraulic components; available in
several configurations with high or low static pressure
single pump or reserve pump (see configurator).

(always passed by)
Compensates the difference in volume between finned
coil and plate exchanger, retaining excess liquid.
DEHYDRATOR FILTER
Hermetic-mechanical with cartridges made of ceramic
and hygroscopic material, able to withhold impurities
and any traces of humidity present in the cooling
circuit.
NON-RETURN VALVES
Allows one-way flow of the refrigerant.

Mechanical valves, with external equaliser positioned
at evaporator outlet, modulates the flow of gas to the
evaporator, depending on the heat load, in order to
ensure a correct heating level of the intake gas.
SOLENOID VALVES
The valve closes when the compressor switches off,
blocking the flow of refrigerant gas to the evaporator,
recovery and the coil.
INDICATOR FOR LIQUID
Used to check presence of humidity in cooling circuit.

5.3. STANDARD HYDRAULIC CIRCUIT
WATER FILTERS
Equipped with steel filtering mesh, prevents the heat
exchangers both of the system side and the DHW/
heating system side from clogging.
FLOW SWITCHES
They have the task of controlling that there is water
circulation inside the heat exchangers; if this is not the
case, they block the unit.
AIR VENT VALVE
Mounted on the top of the hydraulic system; they
discharge possible air pockets.
5.3.1. COMPONENTS OF HYDRAULIC CIRCUIT IN
CONFIGURABLE VERSIONS 
PUMPS
High or low static pressure.
EXPANSION VESSEL
With nitrogen pre-load membrane.
SAFETY VALVE
Equipped with a piped discharger, intervenes by
discharging the over pressure in case of anomalous
pressures.
SYSTEM STORAGE TANK 
Made of steel to reduce heat loss and to eliminate
the formation of condensation, insulated by thick
polyurethane.
Supplied as per standard with 300W electric anti-
freeze resistance (as low as -20°C outside temperature
- 5°C tank water temperature) controlled by anti-freeze
probe inserted in tank.
5.4. SAFETY AND CONTROL COMPONENTS
MANUALLY RESET HIGH PRESSURE SWITCH
With fixed calibration, placed on high pressure side of
cooling circuit, inhibits functioning of compressor if
abnormal work pressure occurs.
LOW PRESSURE TRANSDUCER
Placed on the low pressure side of the cooling circuit,
it signals the work pressure to the control board
generating a pre-warning in the case of anomalous
pressures.
HIGH PRESSURE TRANSDUCER
Placed on the high pressure side of the cooling circuit,
it signals the work pressure to the control board
generating a pre-warning in the case of anomalous
pressures.
COOLING CIRCUIT SAFETY VALVES
They intervene by discharging the overpressure in the
case of anomalous pressures.
- Calibrated at 45 bar on HP branch.
- Calibrated at 30 bar on LP branch.
DCPX CONDENSATION PRESSURE CONTROLLER
This accessory allows correct functioning with external
temperatures lower than 10°C and as low as – 10°C.
It consists of an adjustment circuit board that varies
the number of fan revs according to the condensation
pressure read by the high pressure transducer, in order
to keep it sufficiently high for correct unit functioning.
It also allows correct functioning in heating mode with
external temperatures exceeding 30°C and up to 42°C.
5.5. ELECTRIC CONTROL
AND POWER BOARD
Electric board in compliance with standards EN 60204-
1/IEC 204-1, complete with:
- transformer for the control circuit,
- door lock main isolating switch,
- fuses and contactors for compressors and fans,
- terminals for REMOTE PANEL,
- spring type control circuit terminal board,
- outdoor electric board with double door and
gaskets,
- electronic controller,
- evaporator pump and recovery pump control
consent relay (only for versions without pump
units),
- all numbered cables.
DOORLOCK ISOLATING SWITCH
The electric control board can be accessed by removing
the voltage. Act on the opening lever of the control
board itself. This lever can be locked using one or more
padlocks during maintenance interventions to prevent
the machine being powered up accidentally.
CONTROL BOARD
Allows the complete control of the appliance. For a
more in-depth description please refer to the user
manual.
ATTENTION
(1) For questions of space, in
configurations with storage
tank and built-in pump/s on
the system side, no pumps
can be available on the
recovery side!

Sound power
Aermec determines sound power values in agreement with the
EN ISO 9614-2 Standard, in compliance with that requested by
Eurovent certification.
Sound pressure
Sound pressure measured in free field conditions with
reflective surface (directivity factor Q=2) at 10mt distance
from external surface of unit, in compliance with EN ISO 3744
regulations.

8. OPERATIONAL LIMITS
Note:
1 In SUMMER mode, the unit can be started with
external air 46°C and inlet water 35°C.
In WINTER AND RECOVERY MODE, the unit
can be started with external air -15°C and inlet
water 20°C.
In these conditions, operation is only allowed for
a short amount of time and to bring the system to
the proper temperature.
To shorten this operation, it is recommended to
install a three-way valve which makes it possible
to bypass the water from the utilities to the plant,
until achieving conditions which allow the unit to
work within the allowed operating limits.
8.1. COOLING MODE¹
The units, in standard configuration, are not suitable
for installation in salty environments.
For functioning limits, please refer to the diagrams,
valid for ∆t = 5°C.

ATTENTION
In windy areas, for correct operation
of DCPX it is recommended to install
a windbreak barrier.
It should be installed if wind velocity
is beyond 2.5 m/s.
