Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
This document is currently divided into the following parts:
— Control for heating, ventilating and air-conditioning applications — Part 1: Electronic individual
zone control equipment — Modules M3-5,M4-5,M5-5 [currently at Enquiry stage];

prEN 15500-1:2016 Modules M3-5,M4-5,M5-5 [the present Technical Report; currently at Voting stage].
Introduction
The CENSE project, the discussions between CEN and the Concerted action highlighted the high page
count of the entire package due to a lot of “textbook” information. This resulted in flooding and
confusing the normative text.
A huge amount of informative contents shall indeed be recorded and available for users to properly
understand, apply and nationally adapt the EPB standards.
The detailed technical rules CEN/TS 16629 Detailed Technical Rules ask for a clear separation between
normative and informative contents:
— to avoid flooding and confusing the actual normative part with informative content;
— to reduce the page count of the actual standard;
— to facilitate understanding of the package.
Therefore each EPB standard shall be accompanied by an informative technical report, like this one,
where all informative contents is collected.
Table 1 shows the relative position of this TR within the EN EPB set of standards.

5 Functional and acceptance test
5.1 Objective of the Test methodology
This section provides a test method for the compliance of controllers with the specified control
accuracy in EN 15500-1:2016, 5.4. For the facility of the reader, these definitions will be duplicated in
this Technical Report.
This consists of the following elements:
— testing procedures;
— test facilities description: gives a description of the different equipment pertaining to the bench,
their functions, requirements and specifications;
— description of the simulator: gives details about the simulator framework, user interfaces, models
layout and the running of the tests.
The time parameters for the test procedures are given in the informative Annex A.
5.2 Testing procedures — Test principle
This standard covers the test of a terminal control loop as shown in Figure 1.
The temperature in the room is measured by the temperature sensor of a controller which commands
then the HVAC terminal system in the room, via an actuator e.g. actuator/valve combination for water
systems.
Figure 1 — Example for Control loop for HVAC terminal systems
The test of this controller is carried out by emulation technique in transient state and the real controller
to be tested is implemented in a simulated environment with the room (dynamic model of the heat and
mass transfer) and the HVAC system (Figure 1). The room temperature is finally used to assess the
performance of the controller.
In this approach, the sensor as well as the actuator can be real or simulated.
The test procedures and parameters are described in the following sections.
5.3 Test parameters
5.3.1 Temperature parameters
Tests are conducted by simulating three periods of 20 %, 50 % and 80 % load conditions for HVAC
emitter during heating and cooling tests. The variation of the internal gains in the zone presents also
three periods: 0 %, 30 % and 60 % of the load. Following these variations of the load and internal gains,
six periods are defined:
Table 2 — Definition of the variable test parameters

P1 overshoot
0 % 80 % 20 %
P2 transient
P3 overshoot
30 % 50 % 50 %
P4 transient
P5 overshoot
60 % 20 % 80 %
P6 transient
Tests are performed with the fixed parameters described in Table 3.
Table 3 — Fixed test parameters and room temperature setpoint
Parameter Heating Cooling
Temperature setpoint 20 °C 24 °C
Initial zone temperature 20 °C 24 °C
Outdoor temperature −4 °C 30 °C
5.3.2 Time parameters
The test is split into 6 periods to evaluate the zone controllers performance at three load conditions,
when the controller output is in the process of stabilizing (following a change in load condition) and
when the output is considered stable (after time period T1) as shown in next table. The period T1 is
defined in order to avoid the overshoot of the controller. The period T2 is defined in order to qualify the
performance of the controller associated to a transient state of the building (zone) thermal behaviour
(Table 4).
