Menu button
Menu item selection (see “Menu selection” chapter)
Die The procedure is always identical. Use the menu button to select a menu item. In order to edit this menu item,
confirm using ‘OK’. Then either a dialogue box will appear, showing which button should be used to activate which
function, or you will be taken directly to a display showing a flashing value. A flashing value can be changed using
+/-; this must then be confirmed using ‘OK’. Once you are in a menu item, you can exit it by pressing the menu
button (or by waiting for 30 seconds).
Fan button
Manual fan clearance
The electronic control system must receive a clearance message for the fan to start. This can be issued manually
using this button, or automatically by programming switch points (see chapter on “Fan programme”). If you use the
manual option, please remember that the fan clearance will remain activated until you deactivate it. Therefore, you
should only choose this operating mode if you intend mainly discharging the appliance statically (i.e. without fan
operation), and only intend to switch on the fan occasionally. The green LED above the button will light up once fan
clearance has been activated (manually or programmed).
Supplementary charge button
This button is used to activate a daytime charge (i.e. at peak rates). Once this has been activated, the orange LED
above the button will light up. Since charging is involved, the red LED will also light up. After a maximum of 2
hours, or once a 35% charge level has been reached, the supplementary charge will automatically be de-activated.
This function has been provided in case more heat is unexpectedly required than had been charged on the previ-
ous day.
