Replace the title of Clause D.3 with:

“Control types and functionality”

Add the following subclause to Clause D.3:

‘Self-learning’ means a function that automatically captures the user’s use patterns of the local space heater, and based on those patterns auto-programmes periods of high and low temperatures

The minimum possibility of the self-learning shall be a variable weekly pattern with resolution of 1 h or less to represent the user behaviour switching between at least 2 temperature levels

The means to capture the occupant’s pattern for the heated space the heater is located, shall be embedded in the product or its separate control.

The product shall provide on its user interface or by mobile APP means to check the learnt auto-programmes periods of high and low temperatures.

NOTE 1 Excitation methods can, for example, be based on movements, acoustic, user interface interactions, or light.

The test of a self-learning function shall be in accordance with the manufacturer’s specifications which shall include, at least, an indication about the excitation methods used, the kind of results to be achieved and the learning period.

To check the self-learning function - the product is installed in such a way that the excitation method cannot occur randomly or uncontrollably, and the excitation method is triggered for at least the learning period specified by the manufacturer.

NOTE 2 The learning period is the minimum amount of time required to modify the factory default user use pattern within the given time resolution.

EXAMPLE If the factory default is a low-temperature setting, the time resolution is 1 h, and the excitation method involves detecting a light being on for 10 min to switch from low to high temperature, then the learning period is 1 h. However, if the 10-min light-on period needs to be detected over the same period in two different following weeks, the learning period becomes 1 week plus 1 h.

The activation of the excitation method shall lead to a modification of the user use pattern, and evidence of this should be provided on the product's user interface or via the mobile App.

The effect generated by the activation of the excitation method shall manifest within the time unit used by the self-learning function to which the event belongs.

For testing purposes the learnt user pattern should include a period of low temperature with a duration of 5h to 7h and a period of high temperature with a minimum duration of 4h.

To check the learnt use pattern - proceed according to 18.7 with the following relations and settings:

— The comfort period is the period of high temperature;

— The set-back, frost protection or other state of reduced heat output period are periods of low temperature;

— The device shall be set, according to the user instruction, to follow the self learnt program.

If a product needs some separate related control function for start of heating, the maximum continuous heat output shall be measured while the control required according to the instruction manual of the manufacturer has not been connected.

Replace the content of Clause D.4 with the following:

“As far as applicable, the following information on heat output, power consumption in low power modes, and control functions shall be provided:

— nominal heat output;

— minimum heat output;

— maximum heat output;

— power consumption in off mode;

— power consumption in standby mode;

— power consumption in network standby mode;

— power consumption in idle mode;

— type of room temperature control (see Clause D.3);

— control functions for room temperature control (see Clause D.3).

Replace the 5th paragraph of Clause E.1. with the following:

“The air exchange between the refrigerating chamber and the test chamber is approximately one test chamber volume per h for appliances having a rated power of 1000 W or less and four times test chamber volumes per h for appliances having a rated power of greater than 1000 W.”

Replace the table in E.2 with the following:

Add the following reference:
