1 Modification to Clause 2, “Normative References”
Add the following references:
EN 50564:2011, Electrical and electronic household and office equipment - Measurement of low power
consumption
EN IEC 63474, Electrical and electronic household and office equipment - Measurement of networked standby
power consumption of edge equipment (IEC 63474)
2 Modification to Annex D, “Performance test according to Commission Regulation
(EU) 2015/1188”
Replace the title of Annex D with “Performance tests”
Delete the following definitions in Clause D.2
D.2.2, D.2.5 - D.2.9, D.2.15, D.2.16, D.2.29, D.2.30
Replace the definitions D.2.1, D.2.10 to D.2.14, D.2.17, D.2.19 to D.2.24, and D.2.26 to D.2.28 with the
following:
D.2.1
room temperature control
control which is sensitive to the room temperature and adjustable by the user
D.2.10
nominal heat output
heat output of a local space heater comprising both direct heat output and indirect heat output (where
applicable), when operating at the setting for the maximum heat output that can be maintained over an
extended period, as declared by the manufacturer, expressed in x,xxx kW
D.2.11
minimum heat output (indicative)
P
min
heat output of a local space heater comprising both direct heat output and indirect heat output (where
applicable), when operating at setting of the lowest heat output, as declared by the manufacturer, expressed
in [x,xxx/N.A.] kW
D.2.12
maximum continuous heat output
P
max,c
declared heat output of an electric local space heater when operating at the setting for the maximum heat
output that can be maintained continuously over an extended period, as declared by the manufacturer,
expressed in x,xxx kW
D.2.13
electric power consumption in low power modes
electric power consumption of the product while in the respective low power mode - off mode, standby
mode; idle mode, or networked standby mode -, expressed in x,xx W
Note 1 to entry: The power consumption in these modes shall be measured according to EN 50564 or EN IEC 63474.
D.2.14
standby mode
condition where the product is connected to the mains power source and provides only one or more of the
following functions, which may persist for an indefinite time:
a) reactivation function, or reactivation function and indication of enabled reactivation function;
EN 50559:2013/prA2:2025 (E)
b) reactivation function through a connection to a network (‘networked standby’);
c) information or status display;
Note 1 to entry: In standby mode there is no disconnection from the supply.
D.2.17
single stage heat output, no room temperature control
product which is not capable of varying its heat output automatically and no feedback of room temperature is
present to adapt the heat output automatically
D.2.19
mechanical room temperature control
non-electronic device that allows the product to automatically vary its heat output over a certain time period, in
relation to a certain required level of indoor heating comfort
Note to entry: Varying the heat output can be achieved by variable intermittent switching of the power.
D.2.20
electronic room temperature control
electronic device, either integrated or external, that allows the product to automatically vary its heat output
over a certain time period, in relation to a certain required level of indoor heating comfort
Note to entry: Varying the heat output can be achieved by variable intermittent switching of the power.
D.2.21
electronic room temperature control plus day timer
electronic device, either integrated or external, that allows the product to automatically vary its heat output
over a certain time period, in relation to a certain required level of indoor heating comfort, and allows the
setting of timing and temperature level for a 24-hours timer interval
D.2.22
electronic room temperature control plus week timer
electronic device, either integrated or external, that allows the product to automatically vary its heat output
over a certain time period, in relation to a certain required level of indoor heating comfort, and allows the
setting of timing and temperature levels for a full week
Note 1 to entry: During the 7-day period the settings shall allow a variation on a day-to-day basis
D.2.23
room temperature control, with presence detection
electronic device, either integrated or external, that automatically reduces the setpoint for the room
temperature when no person is detected in
