3.10 OTHER INFORMATION
• If you enter a submenu, and stop using the device for a few
seconds, it will automatically return to the main menu.
• If you are in the main menu, and the device is not being ope-
is rated; it will turn to stand-by mode and the display will only
show a dot. To turn on the screen again, press any key on the
button panel.
• Even if the device is in an OFF cycle, the radiator can still start
working. This is because it has a minimum frost protection
set temperature as per factory set to 7 ºC. This mode is called
FROST PROTECTION and it prevents the room temperature
from going below 7 ºC temperature.
• The device also has a built in sensor that detects any sudden
temperature changes that may occur, i. e. when a window is
opened, air conditioners activated, or any other circumstance
that may prevent the radiator from raising the room tempe-
rature. This mode activates when the temperature decreases
by 3 ºC in 5 minutes. At this stage, the radiator turns off and
shows on the display; this mode stays until this de-
creasing tendency disappears.
