Test result
The eu.bac-accredited test lab provides a test report on each license. The test information relevant to
product use is compiled in the test report summary.
Since in the example for individual room controllers, the control circuit is tested (control accuracy),
the report placed special emphasis on the important characteristics of field components. For
example: the sensor element and its time constant for the temperature sensor and the type of
actuator and its characteristic curve for the valve. Finally, the report documents the test results. In the
case of the individual room controller, the measured values for heating and cooling are documented.
5.2.1. Customer benefits resulting from eu.bac Cert products
For the product user, eu.bac Cert guarantees a high-degree of
· energy efficiency and
· product quality
as set forth in the corresponding EN / ISO standards and European Directives. The energy efficiency
of individual room controllers can be documented as follows:
Impact on energy savings
As mentioned earlier, the control accuracy of individual room controllers is measured and confirmed
with a certificate. The control accuracy has a direct impact on the behavior of room users. The poorer
the control accuracy, the more likely the user is to adjust the room setpoint as a result of poor
comfort.
The graphic below illustrates how much energy (in %) a controller with control accuracy of 0.1 K
saves versus a controller with control accuracy of 1.4 K (resp. 2 K).
Please note the following:
eu.bac has reduced the required minimum control accuracy in EN 15500 from 2 K to 1.4 K.
