ErP temperature controls classes
Basic systems with backup heating (schemes 2 and 4) fulfil the requirements of the
temperature controls class III according to the ErP Directive.
Further schemes with pre-programmed settings for 0-10 V boiler control, room
influence or room control are also available to fulfil the requirements of other
temperature controls classes.
For this purpose, the scheme number is extended to 3 digits. The first digit indicates
the temperature controls class, the second and the third one indicate the desired
basic system.
Example:
In order to select scheme 2 with the settings for temperature controls class VIII,
enter the scheme number 802.
