Companies may apply to participate in any of the above certification sub-programmes:
Are included in the scope:
 Multi-split with data declared and published as combination of outdoor and indoor
units with 2 indoor units only: each unit individually connected to the outdoor unit and
with an expansion device inside the outdoor unit. The 2 indoor units have to be of the
same mounting type. For AC1 capacity ratio must be 1 ± 0.05.
Are excluded from the scope:
 Variable Refrigerant flow Systems
 Multi-split with 3 or more indoor units;
 AC1 multi with 2 indoors and a connection ratio different of 1 ± 0.05;
 Single duct mono-bloc mobile air conditioners;
 Packaged combined air conditioning and control mechanical ventilation;
 Air conditioners up to 12 kW not fulfilling the requirements of Regulation 206/2102
(see APPENDIX D).
“Certify-all”requirement: If a company participates in one of the sub-programmes for Air
Conditioners (AC1, AC2, AC3 and/or CC), all production models, within the scope of that
sub-programme, shall be certified in accordance with the relevant Rating Standard.
III. BASIC OUTLINE OF THE PROGRAMME
Participation in the programme consists of the following:
III.1 Application
After signing the Licence Agreement, the Applicant has to fill in the declaration list for
each sub-programme separately with all models that comply with respectively Rating

III.2 Qualifying procedure
When the declaration file is completed, units selected by Eurovent Certita
Certification shall be tested in an Independent Laboratory chosen by Eurovent Certita
Certification. If the tests show conformity with the relevant Rating Standards,
certification is granted until 3 months after delivery deadline of next testing campaign.
III.3 Repetition procedure
Every year, Eurovent Certita Certification checks whether the certified performances
of the certified products still fulfil the requirements. If the participants fulfilled all
previous test campaigns and provided all the necessary elements and delivered all
the units for the current campaign, the certification is renewed for another campaign
within the timeframe allocated by the certification schedule, see Appendix A.
III.4 Failure treatment
When the test results fail to comply with the requirements of the relevant Rating
Standard(s) the failure treatment shall be applied.
III.5 Complaint procedure
Under special conditions a complaint procedure may be carried out as described in
the Certification Manual.

Reporting of models
In reporting models for certification and for publication on the Eurovent Certified
Performance website, certified ratings shall be given for Packaged Air
Conditioners Units and all combinations of Split Air Conditioners which are
intended by the participant to be used together and which meet the
requirements of the relevant Rating Standard(s).
Optional devices or accessories which are used to obtain the ratings of the
basic unit assembly and which affect the ratings shall be included in the
certification data. Systems having coils with both horizontal and vertical
orientation, when ratings are different, shall be certified to reflect the capacity
and efficiency ratings for both positions.
Besides current models, the Participants shall provide Eurovent Certita
Certification with the list of:
 models under development,
 new models,
 deleted models,
 obsolete models.
d. Basic model group and acoustical family
Each Participant declaration list will be grouped in Basic Model Groups (BMG).
A basic model shall be defined by units which are essentially the same in terms
of thermal performance (±10% on capacity) and function (cooling or heating)
and the same or comparable in terms of basic components, specifically fans,
coils, compressors and motors. In the case of split packaged units, the unit
containing the compressor shall be the reference unit.
The Acoustical Family is defined as same reference for all sizes for outdoor
units and as same reference and same mounting type for indoor units.
IV.2 Selection of units to be tested
Within the programme, tests may be conducted under the following procedures:
 Scheduled tests in qualifying procedure
 Scheduled tests in repetition procedure
 Penalty test
 Complaint test
a.
Number of units to be tested
Eurovent Certita Certification shall select models on the basis of its evaluation
of a Manufacturer's declaration to establish suitable criteria of types and sizes to
be tested. The number of units tested each year per participant shall be as
follows:
 8% (rounded, at least 1) of the number of the listed basic model groups for
AC1
 10% (rounded, at least 1) of the number of the listed basic model groups
for AC2, AC3 and CC.
Examples of rounding (with 10%):
 7 declared units ⇒ 1 selected unit;
 14 declared units ⇒ 1 selected unit;
 15 declared units ⇒ 2 selected units

b. Thermal measurements for AC1
For certification of seasonal efficiency, 30% of the selected units (minimum one
unit) the following measurements at the following conditions shall be performed:
 One running test at Tol. If for the average climate Tol ≥ -10°C and a
measurement has to be made at Tol (chosen conditon), the running test is
unnecessary.
 One point at the standard condition full load, i.e. condition A (35°C) in
cooling mode at TdesignC
 One point at +7°C standard rating condition in heating mode, as specified
in EN14511-2:2013. (if declared)
 One point to be chosen by Eurovent Certita Certification at part load
condition in cooling mode between B, C or D
 One point at the condition F at Tbivalent in heating mode for the average
climate (mandatory to declare)
 One point at the condition F at Tbivalent in heating mode for each additional
optional declared climate
 One point to be chosen by Eurovent Certita Certification at part load
condition in heating mode between A (if different from F), B (if different
from F), C, D or E (if ≠F)
 Tests of Poff, Psb and Pto (cooling mode)
 Pck whenever relevant (in alternance with Poff, Psb and Pto)
 Test of Cd if declared at a different value than the default value (0.25).
For the remaining selected units from the conditions listed above:
 One point selected by Eurovent Certita Certification in cooling

for all units selected.
e.
Acquisition of unit
Deadline for delivery of units to the laboratory together with the technical forms
duly completed, the starting procedure and the payment/order1 is given in the
Certification Schedule (see APPENDIX A).
If units, technical forms, starting procedures and payment/orders are not
delivered within the time limits specified in the notification received from
Eurovent Certita Certification, it is considered as non-application of procedures
(see Certification Manual).
f.
Tests at the laboratory
Units shall be installed in the test facility in accordance with the Participant
published installation instructions. The Participant will provide the laboratory
with full information about the installation, including at least the following items:
 any adjustment of the fan speeds (change of connector, switches, etc.);
 any change of the settings for any part of the unit (for instance, switch for
floor/ceiling mounting, switch for cooling only/heat pump unit, etc.);
 maximum external static pressure for ducted units;
 exact location of the refrigerant piping for multisplit systems, above all for
units intended for more than 2 indoor units;
 any other information necessary to the correct installation of the unit.
The laboratory shall install and check out the units. The procedures used shall
be in accordance with the Participant installation, start-up and service
instructions.
Participant personnel can be allowed to attend the setting-up and the starting of
the unit on request (for inverter units for example) but not the test itself and are
not permitted in the laboratory test room facility.
Prior to the test, the Laboratory personnel are only allowed to:
 Repair leaks
 Repair or replace items damaged by shipping or handling
 Assure correct refrigerant charge
 Assure correct fan speed(s) where adjustable speed fans are used
If the unit is not repairable, it shall be replaced by the Participant.
g. Report of test results
Upon completion of the tests on each unit, the Laboratory will render its
complete report as pdf file to Eurovent Certita Certification. Eurovent Certita
Certification will transmit a copy of the report together with reporting, Form AC4, and re-rating, Form AC-5, test result to the Participant.

h. Selection, shipment and return
Selected units shall be obtained either from the Applicant/Participant production
line or a stocking point, and then delivered to the Laboratory. Following
completion of the tests, the Participant shall arrange for the shipment of the unit.
The Laboratory shall have the responsibility of un-crating, handling, testing and
re-crating the unit for shipment.
A contact person shall be designated by the Applicant/Participant to organise
the shipment to the laboratory, the laboratory shall inform him when the testis
completed.
All transport fees shall be covered by the participant. The laboratory shall not
engage any transport fees.
The Participant has to notify Eurovent Certita Certification within four weeks
after receiving the test report if he intends to recover the tested unit. If the
participant fails to do so, Eurovent Certita Certification will order the laboratory
to dispose of the units and invoice the participant the disposal fee.
For AC1 units the participant can choose to recover all units at the end of the
testing campaign. The Participant has to recover its units within four weeks after
receiving the last test report. For AC2, AC3 and CC units the Participant has to
recover its units within eight weeks after receiving the test report.
IV.3 Failure treatment
a.
Component failure
If any functional component is inoperative, or the unit is damaged and cannot
be repaired at the Laboratory, the unit is considered as a “component failure”. A
new unit shall then be delivered within 2 weeks.
b. Testing at Tol
If the unit fails to start and operate continually for 30 min at Tol the
Applicant/Participant has 2 weeks to choose from the following alternatives:
 Change Tol and ask for a second test on the same unit (SCOP to be
recalculated)
 Change Tol to the lowest fully tested outdoor temperature (-7°C for
average climate, SCOP to be recalculated)
 Maintain Tol and ask for a second test on the same unit
c.
Failure to meet the required capacity ratio (variable capacity)
For variable capacity units in case the tested capacity ratio fails to reach the
required load ratio within  10% the laboratory should contact immediately the
Applicant/Participant to acquire the information to test the closest for the steps
on either side of the required heating load. If the manufacturer fails to provide
the information the unit will be considered as a component failure.
d. Testing of general performances
For each test, a performance item fails when the difference between the
declared value and the measurement differs by more than the acceptable
tolerance (see relevant Rating Standard(s)). A test fails when one or more
performance items fail.
For each failed test, the Applicant/Participant has 4 weeks after notification of
failure to choose between one of the following alternatives:
AC, OM-1-2015
Published December 2014
Page 9 of 30
 Re-rate the products in accordance with the re-rating rules (see dedicated
chapter below);
 Ask for a second test on the same unit;
 Ask for a second test on another unit of the same model selected by
Eurovent Certita Certification.
e.
Penalty tests
An additional unit will be selected for the next test campaign each time there is
a deviation by more than the high tolerance (see relevant Rating Standard) on:
 efficiency and/or capacity;
 sound power level.
Penalty tests following a qualifying procedure need to be validated before the
certification is granted.
f.
Second test
If the Applicant/Participant had shipped back the unit, the complete test shall be
carried out.
If the second test is performed on the same unit (without any modification on
the unit, and not leaving the laboratory), the Applicant/Participant can choose to
repeat only:
 All thermal and pressure measurements
or
 All sound measurements
Note: For a complete test, if the Part Load tests failed but not the Standard
points, the second tests can be carried out only for the Part Load tests
(Tbiv, conditions A to D, TOL) with/without auxiliary test.
IV.4 Repeated failures along the test campaigns
This paragraph refers to paragraph V.6 of the Certification Manual.
The rules regarding Mean Value of Failure (MVF) are described in APPENDIX C.
V.
RE-RATING RULES
For each failed test, the model shall be re-rated according to the following rules:
V.1 Rerating of Tol
If Tol has been changed for second tests and second measurement passed, Tol is
rerated at changed value.
If during second test, second measurement has also failed, Tol will be rerated at the
tested point with the lowest outdoor temperature (-7°C for average climate).
V.2 Seasonal efficiency points: rerating of design load
Whenever the test at extreme/bivalent condition shows a deviation on capacity larger
than the allowed tolerance, the design load is rerated according to the measured
deviation for all models in the same basic model group.
AC, OM-1-2015
Published December 2014
Page 10 of 30
V.3 Rerating of auxiliary power consumption
Whenever the test on auxiliary power consumption shows a deviation larger than the
allowed tolerance, the auxiliary power consumption is rerated according to the
measured deviation for all models in the same basic model group.
V.4 Rerating when capacity and/or efficiency fails
In case of failure on capacity and efficiency, then capacity, efficiency and power input
of the tested model shall be rerated to the measured values.
Deviation on capacity shall be applied to all models in the same basic model group
(BMG).
Deviation on efficiency shall be applied to all models in the same BMG.
Power input shall be recalculated for all models in the same BMG.
In case of failure on capacity only or efficiency only, the power input shall also be
recalculated for all models in the same basic model group.

V.5 Rerating of SEER and SCOP
When second measurement of Tol fails, SCOP of the tested model shall be
recalculated with the assumption that all demands beyond Tol are provided by an
electric backup heater with a COP of 1.
Whenever a measurement at a part-load condition selected by Eurovent Certita
Certification shows a deviation on EER or COP larger than the allowed tolerance, the
§ V.4 shall be applied on all the other part load EER (respectively COP) and then,
SEER and SCOP will be recalculated by Eurovent Certita Certification, to be rerated.
Whenever the test on auxiliary power consumption or/and the test on capacity at
extreme condition/bivalentcondition shows a deviation larger than the allowed
tolerance the value of SCOP/SEER should be recalculated.
In case of recalculation of the SEER or SCOP, the annual energy consumption
should be recalculated for the tested unit.
In case of recalculation of SEER or SCOP and annual energy consumption for the
tested model:
- the deviation on SEER or SCOP shall be applied to all models in the same basic
model group (BMG),

V.6 Rerating on acoustic performances
 If the result on sound power level exceeds the claimed by the tolerance, but
less than than the high tolerance (see relevant Rating Standard), only the tested
model shall be re-rated in accordance with the test result.
 If the result exceeds the claimed value by the tolerance or more, the tested
model shall be re-rated in accordance with the test result. In addition, the whole
product family of the failed model shall be re-rated to the tested deviation value
minus 2 dB(A).

V.7 Possible uprating
At the moment of the annual declaration, an uprating of performances from a same
BMG is allowed:
- If the deviation of tested unit (in the BMG) is above inversed tolerance
Or if:
- Units are not already tested and rerated and
- Units of the BMG, if we received the proof (=report) that the tested unit was very
underrated

Start-up procedure
Note: Once frequencies and expansion valves opening are fixed, no further changes will
be allowed until test completion.
If answer to clause 3 is YES, a detailed start-up procedure shall be attached.
VERY IMPORTANT: Attached start-up proceduret shall be drafted with enough details to
ensure the laboratory personal will be able to set the unit at the first try. In particular,
special care shall be given to the following items:
 Initial state of the following items (before starting the configuration):
 wired/remote controller model status (ON or OFF)
 appliance status (ON or OFF)
 mode (cooling, heating, ventilation, auto, etc.)
 room temperature range requirements (if yes, specify clearly), Temperature
requirements cannot be closer than ± 2 K from the rating conditions.
In addition:
 Indicate if the remote controller shall be configured with the indoor unit(s) receiving or
not the signals from the remote controller.
 When entering TEST MODE, indicate if the appliance will give a feedback (acoustic
or visible) to acknowledge the setting.
 Indicate the louver position, and the method to reach it. A drawing may be useful.
 For multisplit systems, please clearly specify if the starting procedure has to be
performed for all indoor units at the same time, or in which order.
5.
Time before beginning of the measurement period
Please note that the measurement period will begin 60 minutes (heating mode) or 70 min
(heating mode) after starting the unit. This means that the unit shall be running in
TEST MODE by that time.
6.
Default start up procedure
When there are no details on start-up supplied with the units, the normal start-up
procedure used by the laboratory will be as follows:
COOLING CAPACITY TESTING AND SOUND POWER DETERMINATION
Configuration of the remote controller:
 Mode: Cooling mode*
AC, OM-1-2015
Published December 2014
Page 24 of 30
 Temperature set: Minimum allowed by remote controller without including special
modes like LOW temperature function.
 Fan speed: Maximum allowed by remote controller without including special modes
like TURBO mode.
 Louver: Maximum airflow position**
HEATING CAPACITY TESTING
Configuration of the remote controller:
 Mode: Heating mode*
 Temperature set: Maximum allowed by remote controller without including special
modes like HIGH temperature function.
 Fan speed: Maximum allowed by remote controller without including special modes
like TURBO mode.
 Louver: Maximum airflow position**
* Any other functions, like eco mode, display backlighting, ionizer, etc will be kept as default after inserting the batteries
in the remote controller or switching the power on for wired remote controllers. **The louver position for maximum airflow
is only checked visually so there is a risk not to exactly be in the maximum airflow position.

APPENDIX C.
Calculation method and implementation of MVF
C.I. General
Mean Value of Failure (MVF) is equal, for each manufacturer and for each
considered characteristic, to the ratio between the total number of measurements
above the “High deviation limit” (see table below) and the total performed
measurements in the considered years.
MHFV
Mean High FailureValue

 Numb er of measurements failed with high deviation
 Numb er of measurements performed
Number of considered years
Number of considered years
When there is a second test on a unit, then the first measurements are not taken into
account.
A manufacturer is expelled from the Eurovent Certified Performance Programme for
one year if, for at least one considered characteristic, the mean value of MVF is
higher than the limit z.
Current Failure treatment (re-rating and additional tests) still applies above the
“Eurovent AC tolerance” (see IV.3).

C.II. Implementation & newcomers
At the end of 2009 test campaign, Eurovent Certita Certification takes into
consideration the last two test campaign data of each manufacturer. At the end of
2010 test campaign and at the end of each following year, Eurovent Certita
Certification takes into consideration the last three test campaign data of each
manufacturer.
Data of new participants will be first taken into consideration after two test campaigns
(including qualifying tests).
C.III. Notification of being expelled
A participant who is going to be expelled will receive a notification from Eurovent
Certita Certification, with a possible additional selected unit to be tested. The purpose
of this additional test is to give the participant the opportunity to comply with the
limits. The response to Eurovent Certita Certification with confirmation of request for
additional testing has to be done within 30 days after this notification, and the unit
has to be delivered within 45 days after this notification.

A manufacturer that leaves the programme because he has been expelled should
complete the qualifying procedure within the year for which he has been expelled in
order to rejoin for the next year. He becomes a newcomer.

ECO-DESIGN AND ENERGY LABELLING
Commission Regulation (EU) No 206/2012 implementing Directive 2009/125/EC of the
European Parliament and of the Council with regard to ecodesign requirements for air
conditioners and comfort fans gives requirements for all air conditioners with the cooling
capacity under 12 kW (AC1) introduced on the European market after 1 January 2013.
The Directive defines maximum sound power levels and energy efficiency as given in the
following tables.
Commission Regulation(EU) No 626/2011 supplementing Directive 2010/30/EU of the
European Parliament and of the Council with regard to energy labelling of air conditioners
makes mandatory energy labelling of all air conditioners with the cooling capacity under
12 kW (AC1) introduced on the European market after the 1st January 2013. The Directive
defines for each function the energy class going from A++ (more efficient) to G (less
efficient). The classification is given in the following table.
