The EU-297v3 room regulator is designed to maintain the pre-set room temperature by sending a signal to the heating
device or the main controller when the pre- set room temperature has been reached. After receiving such a signal, the
heating device turns off.

appears on the main screen. The user may define the pre-set temperature and (after tapping on MENU
again) the time of entering day and night mode.
