Room temperature controller | Scenes
Precondition
The scene function must be enabled on the parameter page "Room temperature con-
troller -> RTCx - General -> Enabled functions".
￭ On the parameter page "Room temperature controller -> RTCx - General ->
Scenes", activate the parameter "Delay scene recall".
The delay time is now activated and can be configured separately. The delay
only affects the scene recall of the room temperature controller. The delay
time is started on arrival of a recall telegram. Only after the time has elapsed is
the corresponding scene called up and the operating mode set.
Each scene recall telegram restarts the delay time and retriggers it. If a new
scene recall telegram is received while a delay is active (scene recall not yet
executed), the old (and not yet recalled scene) will be rejected and only the
scene last received executed.
The scene recall delay has no influence on the storage of scene values. A
scene storage telegram within a scene recall delay terminates the delay and
thus the scene recall.
Presetting the behaviour during ETS programming
When saving a scene, the operating modes are stored internally in the device in a
non-volatile manner. To ensure that the stored values are not replaced by the origin-
ally programmed scene operating modes during an ETS programming operation of
the application program or the parameters, the actuator can prevent the operating
modes from being overwritten. As an alternative, the original values can be reloaded
into the device during each programming run of the ETS.
Precondition
The scene function must be enabled on the parameter page "Room temperature con-
troller x -> RTCx - General -> Enabled functions".
￭ Activate the parameter "Overwrite values stored in the device during the ETS
programming operation" on the parameter page "Room temperature controller
x -> RTCx - General -> Scenes".
With each ETS programming operation of the application program or the para-
meters, the scene operating modes configured in the ETS are programmed
into the actuator. This may overwrite the scene operating modes stored in the
device by means of a storage function.
￭ Deactivate the parameter "Overwrite values stored in the device during the
ETS programming operation".
Scene operating modes that may have been stored in the device by means of
a storage function are maintained. If no scene switching states have been
stored, the last operating modes programmed in by the ETS remain valid.
When commissioning the actuator for the first time, the parameter should be
activated so that the operating mode is initialised to valid scene operating
modes.
