Serie

WINTER : the cooling cycle makes it possible to absorb energy (heat at low temperature) from the external environment and to transfer it to the area to be heated.

1. The compressor compresses the refrigerant fluid, placing it at high pressure and high temperature.

2. The 4-way valve reverses the flow with respect to respect to SUMMER operation.

3. In the plate exchanger, the water that returns to the system absorbs heat from the refrigerant.

4. As it cools, the refrigerant condenses and becomes liquid.

5. The expansion valve causes a sudden drop in the pressure of the refrigerant, which becomes very cold as its volume increases.

6. In the external coil, the cold refrigerant evaporates and absorbs heat from the external air. In this phase, as the coil cools, it may freeze. This is why the cycle is automatically reversed periodically for a short time so as to defrost it

1.5 PRINCIPLE OF OPERATION

SUMMER: the cooling cycle allows the transfer of excess indoor heat to the external environment.

1. The compressor compresses the refrigerant gas, placing it at high pressure and high temperature.

2. In the external coil, the refrigerant is cooled, and the heat is released into the environment by means of the fan. This is why the coil needs to be kept clean and free of obstacles.

3. When it cools, the refrigerant becomes liquid.

4. The expansion valve causes a sudden drop in the pressure of the refrigerant, which becomes very cold as its volume increases.

5. In the exchanger, the refrigerant evaporates and absorbs the heat from the water that returns to the system, cooling it.

For detailed information (dimensions, weight, technical characteristics etc.) please refer to the TECHNICAL INFORMATION section.

Use single protection devices : gloves, glasses ecc.

During positioning consider these elements :

• technical spaces required for the machine and system

• place where the machine will be installed

• electrical connections

• water connections

• air / aeraulic ducts

Do not considerer these elements could decrease performances and operational life of the unit.

3.2 FUNCTIONAL SPACES

Functional spaces are designed to:

• guarantee good unit operation

• carry out maintenance operations

• protect authorized operators and exposed people

Respect all functional spaces indicated in the TECHNICAL INFORMATION section.

Double all functional spaces if two or more unit are aligned.

3.3 POSITIONING

Units are designed to be installed:

• EXTERNAL

• in fixed positions

Limit vibration transmission:

• use antivibration devices on unit bearing points

• install flexible joints on the hydraulic connections

Choose the installation place according to the following criteria:

• Customer approval

• safe accessible position

• technical spaces requested by the unit

• spaces for the air intake/exhaust

• avoid flood-prone places

• verify unit weight and bearing point capacity

• verify that all bearing points are aligned and leveled

• install the unit raised from the ground

• max. distance allowed by the electrical connections

Prefer places where the unit doesn’t disturb the neighbours. Avoid installations next to bedrooms or windows. Avoid snow accumulations on batteries.

Protect the unit with an appropriate fencing to avoid the access to a not authorized personnel (babies, vandals etc.) A correct circulation of the air is indispensible to guarantee the good working order of the machine. Avoid therefore:

• obstacles to the airflow;

• exchange difficulties;

• leaves or other foreign bodies that can obstruct the

exchange batteries;

• winds that hinder or favour the airflow;

• heat or pollution sources close to the unit (chimneys,

extractors etc);

• stratification (cold air that stagnates at the bottom);

• recirculation (expelled air that is sucked in again);

• positioning below the level of the threshold, close to very

high walls, attics or in angles that could give rise to stratification or recirculation phenomenons.

Ignoring the previous indications could:

• energy efficiency decrease;

• blocks due to HIGH PRESSURE (in summer) or LOW

PRESSURE (in winter).

3.4 CONDENSATE WATER

When a heat pump is running it produces a considerable amount of water due to the defrosting cycles of the external coil.

The condensation must be eliminated in a manner to avoid wetting pedestrian areas.

With extensive very cold outdoor temperatures, condensation could freeze and block the flow, causing a slow build-up of ice; therefore special attention must be paid to eliminating condensation, raising the unit off the ground and evaluating whether antifreeze elements should be installed

3.5 FRESH AIR PROBE - OPTIONAL

The external probe allows to automatically change the unit set point according to the external enthalpy (temperature + humidity).

It is then possible to optimize the unit energy efficiency.

POSITIONING

The sensor should not be influenced by factors that can distort the reading (eg direct sunlight, air exhausted from the fan or other sources, contact with the unit structure or other heat sources, accumulations of snow / ice).

Examples to position the external probe :

• A roof

• B under a terrace

• C if at free wall provide a

small roofing

4.1 PRELIMINARY INFORMATION

Selection and installation of system components must be carry out by installer.

Following you will find some indications to integrate with what is provided by the local regulations in force and by the good technical laws.

4.2 COMPONENTS

CUT-OFF VALVES

• Installed at inlet and outlet (both on the water technique

circuit as well as that of the hot domestic water) allow maintenance operations without having to empty the system .

THERMOMETERS AND MANOMETERS

• Installed at entry and exit of the main elements facilitate

inspection and maintenance.

AIR BLEED VALVE

• Installed in all of the highest points of the system allowing

the venting of the circuits air..

DRAINAGE TAPS

• Installed in the lowest points of the system to allow

bleeding.

EXPANSION TANK

• It keeps a correct system pressure when the water

temperature changes. It must be dimensioned as a function of water plant volume and temperature.

WATER FILTER

• If not present on-board the machine, must be installed

immediately in the water input of the unit, in a position that is easily accessible for cleaning.

• The filter never should be removed, this operation

invalidates the guaranty

SUPPORTS

• The hydraulic pipes weight mustn’t burden on the unit

connections ..

FLOW SWITCH

• The flow switch must be present as a component of the

system

4.3 OPERATION SEQUENCE

1. Carefully wash the system with clean water: fill and drain

the system several times.

2. Apply additives to prevent corrosion, fouling, formation of

mud and algae.

3. Fill the plant

4. Execute leakage test.

5. Isolate the pipes to avoid heat dispersions and formation

of condensate.

6. Leave various point of service free (wells, vent-holes etc).

Neglecting the washing will lead to several filter cleaning interventions and at worst cases can cause damages to the exchangers and the other parts.

4.4 WATER QUALITY

The water quality is determined by the following factors, avoid therefore:

• Inorganic salts

• pH

• Biological load (seaweeds etc)

• Suspended solids

• Dissolved oxygen

Water with inadequate characteristics can cause:

• pressure drop increase

• energy efficiency decrease

• corrosive symptom increase

4.5 RISK OF FREEZE

If the unit or the relative water connections can be subject to temperatures close to 0°C adopt measures for prevent risk of freeze.

For example:

• Mix water with ethylene glycol

• Safeguard the pipes with heating cables placed under the

insulation

• Empty the system in cases of long non-use and check that:

• there are no closed taps present that could trap water

even after emptying

• there are no low points in which water can stagnate

even after emptying; carry out any blowing required .

4.6 ANTI-FREEZE SOLUTION

Consider that the use of anti-freeze solution determines an increase in a pressure drop.

Make sure that the glycol type utilized is inhibited (not corrosive) and compatible with the hydraulic circuit components (pump etc).

Do not use different glicol mixture (i.e. ethylene with propylene)

4.7 WATER CONNECTIONS

• Take away the supplied connection union by acting on the

connection joint.

• Weld the union to the installation pipe.

• Perform the connection between the installation pipe and

the evaporator, using the joint. Do not weld the system pipe with the connection joint attached.

The rubber gasket might be irreparably damaged.

Unit can be switched on and off by:

ON – OFF

COOLING The compressor is activated with outlet temperature higher than set point

• remote or service keypad

• remote switch (see ELECTRICAL CONNECTIONS paragraph)

• Supervisor

To switch from cooling to heating and vice versa, proceed as follows:

• Turn the unit OFF

• Wait until the plant water temperature (and external air) fall within the operating limits.

They can be switched over from the remote controls (refer to the ELECTRIC WIRING paragraph).

ATUS

HEATING The compressor is activated with outlet temperature lower than set point

ECO

A secondary set-point can be used, with respect to the comfort setting. In heating the ECO-set is lower than the standard set , in cooling the ECO-set is higher than the standard set.

MAINTENANCE the plant can be kept within the operating limits even when the unit is OFF or on STANDBY

DEFROSTING The external coil is free from ice stopping the fans and forcing for a short period the unit in cooling

THERMOREGULATION

The thermoregulation is based on the OUTLET temperature.

The unit is dimensioned for a determined TOTAL HEAD between input and output water temperature.

Usually the project step is 5°C; if the value is different, it is necessary reset parameters 37 and 38 (accessible to the service centre).

In function of the total head, the installation determines the head quote that every resource (compressor, heating elements) is able to provide: the STEP HEAD.

The control logic insert gradually the resources when the outlet temperature is higher than the set point + the head step.

The resources are activated one at a time and only at the SCAN TIME expiring.

The scan time is not fixed but it changes in function of the margin between the water outlet temperature and the Set point value. Higher is the margin value (both in positive and in negative) shorter will be the space among the scan points.

The scan time value is visualized at status 4; when the status 3 has reached the status 4 value, the compressor operating request is activated.

What above described, refer to the COOLING operating; in HEATING le logic is the same but “overturned” ( insertion of the compressor for outlet temperature< set-point –step jump )

SET-POINT COMPENSATIONS

The compensations are evolved functions to protect the compressors and to adapt, as far as possible, the unit operating to the installation and use characteristics.

The compensations prolong the compressor operating time and limit the start number; to do this they delay the compressor insertion point adding an offset.

COMPENSATED compressor activation point

non compensated compressor activation point

• The compensation on the DURATION is useful when the installation water content is limited.

• The compensation on the CHARGE is useful if the variable charge is present.

For the enabling and the configuration is necessary the parameter modification with reserved access to the service centres.

In industrial applications where is requested a temperature check is possible to disable the COMPENSATIONS.

SET-POINT CORRECTIONS

The correction aim is to optimize the unit energetic efficiency.

To do this the corrections modify the set point in a dynamic way in function of determined variables: for example in summer operating with low external temperatures, so with a reduced charge, is possible to obtain the internal comfort also with set point higher than standard, obtaining an higher energetic efficiency.

CORRECTION

The static set point can so be modified in a dynamic way by two CORRECTIONS based on as many unit external factors:

• correction based on the ext. temp. / enthalpy

• correction based on the Water reset (4-20 mA signal provided by the Client)

The correct set point, to whom have been summed or removed the corrections, is named ACTUAL set-point and it is visible at status n°1. The STATA menu visualizes the compensation value on the ext. temperature (status 5) and WR (status 6) For further details see the ELECTRICAL CONNECTIONS section

SET POINT CORRECTION FOR COMPRESSOR OPERATING LIMIT

The function is active only in HEATING; it allows extending the operating limits decreasing gradually the set point when the external temperature descends more than determined limits.

In the graph, the correction action is indicated by the curve left side (B). The curve right side (A) represents the correction state on the external temperature (optional, see the ELECTRICAL CONNECTIONS section). The following data are indicatives .

DEFROSTING

The defrosting aim is to maintain the external coil free from ice during the winter mode : to do that the unit is periodically commuted in “summer” mode for few minutes and the fans are stopped. The defrosting phase is started when the evaporating pressure falls below a fixed value . A count starts and at its end, if the temperature on the coil is lower than the threshold, the defrosting starts . The count changes according to the external temperature and to the ice quantity on the coil ( by some indirect variables ) . When defrosting is complete, the unit returns automatically to the Winter mode. Defrosting is managed according to the external temperature and humidity in the air:

• more humidity = frequent defrosting

• external temperature next to 0°C = frequent defrosting

By the EXTERNAL HUIDITY PROBE option the defrosting is optimised according to the external temperature and humidity .

CIRCULATION PUMP

The pump is always activated with the units ON. The delivery capacity is variable to soften the thermal shock to the compressors when the plant temperature is close to the threshold limits. Delivery capacity depends on the intake temperature:

• SUMMER: high water temperature reduces delivery

• WINTER: low water temperature reduces delivery

VENTILATION

Fans are controlled with a variable speed:

• in SUMMER, the speed increases according to the increase of external air temperature

• in WINTER the speed increases according to the decrease of the external tempe

SET POINT

SUMMER - WINTER

The thermoregulator manages two set points:

• SUMMER set-point for cooling (parameter 32)

• WINTER set-point for heating (parameter 33)

The control is performed on the OUTLET TEMPERATURE, comparing it with the actual set-point value (visible at status 1).

SET-POINT CALCULATION:

• desired medium outlet water temperature = 7°C

• Project temperature differential = 5°C (that is inlet water = 12°C)

• ¼ of the project temperature differential = 5 / 4 = 1.25°C

• set-point to be set = 7 – 1.25 = 5.7°C

SECONDARY SET POINT – ECO

A secondary set point can be used with different levels to the “normal” set point. It is normally set to give lower energy consumption with respect to the comfort setting:

• The SECONDARY SUMMER set point is higher than the SUMMER setting.

• The SECONDARY WINTER set point is lower than the WINTER setting.

It can be set according to individual requirements.

• Secondary summer set-point parameter 29

• Secondary winter set-point parameter 30

It can be activated from the keyboard, supervisor unit or the remote control. To change it using the remote control refer to the ELECTRIC WIRING paragraph.

Page 23

7 - CONTROL

MAINTENANCE

This way, the plant can be kept within the operating limits even when the unit is OFF or on STANDBY, for example during the weekend or the nighttime. Periodically the system activates the circulation pump, measures the water temperature and activates the compressor, if required, to take the water temperature to the set-point level.

• Summer maintenance set-point par 42

• Winter maintenance set-point par 43

This function is activated by parameters 44 (activate summer maintenance level) and 45 (activate winter maintenance level). With unit in maintenance mode, the display visualizes STB .

FUNCTIONING WITH ETHYLENE GLYCOL

The units foreseen to function with glycoled water come out from the premise with standard parameters. After having added glycol ethylene to water, the technician will properly set the plant.

ALARMS

BEFORE RESETTING THE ALARM, IDENTIFY AND ELIMINATE THE CAUSE OF ITS ACTIVATION.

REPEATED RESETS CAN CAUSE IRREVERSIBLE DAMAGES.

The ALARMS show a potentially dangerous situation for machine safety. Before resetting the alarm, discover and remove the cause: repeated resetting could cause irreversible damage. To avoid this, the unit can only be reset MANUALLY from the keyboard (only when the cause for the alarm has been removed).

PRE-ALARMS and SIGNALS warn of a risky situation. These could be acceptable only if they happen occasionally or in transitory situations (for example when the plant is being started up). They are reset AUTOMATICALLY, as soon as the cause has been removed, without any input from the keyboard. The pre-alarms are signalled by the fixed C code (not flashing) and on the right the control temperature.

The FAULTS warn of problems with the probes and transducers, and are reset AUTOMATICALLY to allow the unit to continue running, perhaps with fewer functions.

In case of doubt, always contact an authorised service centre.

The presence of an alarm is signalled by the ALARM CODE flashing and the time at which the alarm/alarms occurred.

The cumulative block relay activates simultaneously to the alarm code visualization. Certain alarms, in particular PRE-ALARMS, do not activate the relays.

8 - MAINTENANCE

8.1 GENERAL

Maintenance must be done by authorized centres or by qualified personnel

The maintenance enables:

• maintain the unit efficiency

• Reduce the deterioration speed to whom every equipment

is subject over time

• Assemble information and data to understand the state of

the unit efficiency and avoid possible damages

8.2 INSPECTIONS FREQUENCY

The inspections should be carried out at least every six months

The frequency, however, depends on the use .

In the event of frequent use it is recommended to plan inspections at close intervals :

• frequent use (continuous or very intermittent use, near the

operating limits, etc)

• critical use (service necessary) .

8.3 MACHINE BOOKLET

It’s advisable to create a machine booklet to take notes of the

unit interventions.

In this way will be easier marker the various interventions and

will be e facilitate any troubleshooting.

Report on the booklet :

• data

• type of intervention effected

• intervention description

• Carried out measures etc ..

8.4 PUT A REST

If a long period of inactivity is foreseen

• Turn of the power in order to avoid electrical risks or

damages by lightning strike

• avoid the risk of frosts (empty or add glycol in the plant

sections subjected to temperatures below zero , power

antifreeze resistances if are present )

It’s recommended that the starter after the period of detention

is made by a qualified technician, especially after seasonal

stops or seasonal switch.

When restarting, refer to the START-UP section .

Schedule technical assistance in advance to avoid hitches and

be able to use the installation when necessary.

8.5 WATER FILTER

8.7 WATER EXCHANGER

It is very important for the exchanger to be able to provide the

maximum thermal exchange. Therefore, it is essential for the

inner surfaces to be clean of dirt and incrustations.

Periodically check the difference between the temperature of

the supply water and the condensation temperature. If the

difference is greater than 8 °C – 10 ° C it is advisable to clean

the exchanger.

The clearing must be effected :

• With circulation opposite to the usual one

• With a speed at least 1,5 times higher than the nominal one

• With an appropriate product moderately acid (95% water +

5% phosphoric acid

• After the cleaning rince with water to inhibe the detergent

rests.

8.8 ELECTRIC FANS

Check :

• the fans and the relative protection gridsare well fixed

• The fan bearings (evident by noise and anomalous

vibrations )

• the terminal protection covers are closed and the cable

holders are properly positioned

8.9 AIR COIL

Contact with the exchanger fins can cause cuts. Wear

protective gloves to perform the above described operations.

It is extremely important that the battery gives the maximum

thermal exchange; therefore, its surface must be cleaned from

dust and deposits. Remove all impurities from the surface.

It is extremely important that the battery gives the maximum

thermal exchange; therefore, its surface must be cleaned from

dust and deposits. Remove all impurities from the surface.

Using an air pressure gun, clean the aluminum surface of the

battery. Be careful to direct the air in the opposite direction of

the fan air movement.

Hold the gun parallel to the fins to avoid damages. As an

alternative, an aspirator can be used to suck impurities from

the air input side.

Verify that the aluminum fins are not bent or damaged. In the

event of damages, contact the authorized assistance center

and get the battery “ironed out” in order to restore the initial

condition for an optimal air flow

Verify that there are no impurities which hinder the smooth passage of water.

8.6 CIRCULATION PUMPS

Verify :

• no leaks

• Bearing status (anomalies are highlighted by abnormal

noise and vibration)

• The closing of the terminals cover and the correct

positioning of the cable glands.

with the symbol on the side.

With the aim of protecting the environment, all of our units are

produced in compliance with Directive EC on waste electrical

and electronic equipment (WEEE).

The potential effects on the environment and on human health

due to the presence of hazardous substances are shown in the

use and maintenance manual in the section on residual risks.

Information in addition to that indicated below, if required, can

be obtained from the manufacturer/distributor/importer, who

are responsible for the collection/handling of waste originating

from equipment covered by EC - WEEE. This information is

also available from the retailer who sold this appliance or from

the local authorities who handle waste.

Directive EC - WEEE requires disposal and recycling of

electrical and electronic equipment as described therein to be

handled through appropriate collection, in suitable centres,

separate from collection for the disposal of mixed urban waste.

The user must not dispose of the unit at the end of its life cycle

as urban waste. It must instead be handed over to appropriate

collection centres as set forth by current standards or as

instructed by the distributor.

If disposal takes places at the same time as delivery of a new

electrical or electronic equipment for the same family, the

product may be collected directly by the distributor.

Check that the installation has been implemented by qualified technical personnel only and that the instructions contained in the present manual and the local regulations in force have been adhered to.

The installation of the unit in a place where even infrequent leaks of inflammable gas and the accumulation of this gas in the area surrounding the area occur could cause explosions or fires.

Carefully check the positioning of the unit.

The installation of the unit in a place unsuited to support its weight and/or guarantee adequate anchorage may cause the fall or the tipping of the unit with the consequent damage to things, people or the unit itself.

Carefully check the positioning and the anchoring of the unit.

Easy access to the unit by children, unauthorised persons or animals may be the source of accidents, some serious.

Install the unit in areas which are only accessible to authorised person and/or provide protection against intrusion into the danger zone .

11.5 GENERAL RISKS

Smell of burning, smoke or other signals of serious anomalies may indicate a situation which could cause damage to people, things or the unit itself. Electrically isolate the unit (yellow-red isolator).

Contact the authorised service centre to identify and resolve the problem at the source of the anomaly.

Accidental contact with exchange batteries, compressors, air

delivery tubes or other components may cause injuries and/or burns.

Always wear suitable clothing including protective gloves to work inside the danger zone.

Maintenance and repair operations carried out by nonqualified personnel may cause damge to persons, things or the unit itself.

Always contact the qualified assistance centre.

Failing to close the unit panels or failure to check the correct tightening of all of the panelling fixing screws may cause damage to persons, things or the unit itself.

Periodically check that all of the panels are correctly closed and fixed.

If there is a fire the temperature of the refrigerant could reach values that increase the pressure to beyond the safety valve with the consequent possible projection of the refrigerant itself or explosion of the circuit parts that remain isolated by the closure of the tap. Do not remain in the vicinity of the safety valve and never leave the refrigerating system taps closed.

11.6 ELECTRICS PARTS

An incomplete attachment line to the electric network or with incorrectly sized cables and/or unsuitable protective devices can cause electric shocks, intoxication, damage to the unit or fires.

Carry out all of the work on the electric system referring to the electric layout and the present manual ensuring the use of a system thereto dedicated.

An incorrect fixing of the electric components cover may favour the entry of dust, water etc inside and may consequently can electric shocks, damage to the unit or fires.

Always fix the unit cover properly.

When the metallic mass of the unit is under voltage and is not correctly connected to the earthing system it may be as source of electric shock and electrocution.

Always pay particular attention to the implementation of the earthing system connections.

Contact with parts under voltage accessible inside the unit after the removal of the guards can cause electric shocks, burns and electrocution.

Open and padlock the general isolator prior to removing the guards and signal work in progress with the appropriate shield.

Contact with parts that could be under voltage due to the start up of the unit may cause electric shocks, burns and electrocution.

When voltage is necessary for the circuit open the isolator on the attachment line of the unit itself, padlock it and display the appropriate warning shield.
