The time program and the special day program are set on the central

In case of central apartment unit override, the display shows the cen-
tral apartment unit symbol

Room timer function
The Room timer button (
) allows you to force the system to main-
tain the Comfort temperature for an adjustable period of time.
Pressing the button displays the room timer symbol, the Comfort
setpoint symbol and the duration of the selected Comfort mode
(00:00).
Every pressing of the Room timer
button extends the duration of Com-
fort mode by 30 minutes. Continuous
pressure on the room timer button
speeds up setting.
If no button is pressed for 4 seconds, the setting is adopted and Comfort
mode is displayed.
The display shows the hourglass
which disappears as soon as the cen-
tral apartment unit takes over the set-
tings entered on the room unit.
When the room timer function is active and the Room timer button is pressed,
the timer’s remaining time is displayed. It can be set to 30 minutes by pressing
again the Room timer button and each additional push of the button extends
the time by another 30 minutes.
An active room timer function can be aborted by setting the extension time to
00:00, or by pressing the Mode button.
For the room timer function to be activated, the apartment operating
mode must be set to ”Auto”. In addition, no absence or holiday function
for the apartment may be active.
Readjust the room temperature setpoint
Room temperature setpoint readjustments by a maximum of
+/- 3 K can be made with the setting knob. When turning the
knob one step, the display shows the current room temperature
setpoint readjustment. Each step represents another readjust-
ment of 0.5 K.
