°C
°C
Comfort operation
Application:
– You are in the room for a longer period of time; the comfort temperature is to be
reached.
Behaviour of the RTC:
– The display indicates the set-value temperature that has been set. The controller
aims at this temperature.
ECO mode
Application:
– You are leaving the room for a few hours; the room temperature is to be reduced
to save energy. However, the room should not cool down completely.
Behaviour of the RTC:
– The display shows the icon for "ECO". The temperature is reduced by the pre-
programmed value. The fan speed levels can be limited according to the
parameter setting.
Off mode
Application:
– The room is not being used for a longer period of time.
Behaviour of the RTC:
– The display shows "OFF". The heating valves are closed (frost protection is
active).
Frost/heat protection
Application:
– The function switches on automatically when a window contact has been
connected and the window is being opened.
Behaviour of the RTC:
– The display indicates the icon for frost/heat protection. The heating valves close. If
the room temperature drops below 7°C, the heating is switched on again to
prevent damage to the building.
Heating/cooling switchover
Application:
– The device is suitable for both heating and cooling mode. The switchover of the
two operating modes takes place either via a binary input, which has been
configured as heating/cooling reverser, or via a press of the button [3] and
subsequent selection via the set value adjustment buttons [1/6].
Behaviour of the RTC:
– The device operates in heating mode. The display shows the icon for heating. The
settings for heating mode are available.
The heating unit, e.g. a heat pump, switches into cooling mode. All RTCs in the
building receive information via the KNX bus and switch from heating mode into
cooling mode. The display shows the icon for cooling. The settings for cooling mode
are available.

Fan operation
Application:
– You want to change the automatically selected fan speed level and set the desired
fan speed level manually on the device. The control of the temperature in the room
continues to be active.
Behaviour of the RTC:
– The display indicates the set fan speed level and "Auto". The room is heated or
cooled via a 3-stage fan coil. The fan sets the necessary fan speed level
automatically in dependence of the control.
