Product Manual RCUXXYY
EAE KNX Room Control Unit RCUXXYY PM R1.0
©EAE Technology www.eaetechnology.com Page 16 / 80
This parameter can be used to enable/disable manual control. If manual operation is enabled,
connected load can be controlled via the corresponding channel button on the device.
▪Set the parameter to “enable”
This selection is used to enable manual operation.
▪Set the parameter to “disable”
This selection is used to disable manual operation.
Reset manual operation to KNX operation
*via push button
automatically and via push button
This parameter determines how long manual operation remains activated.
Time for automatic reset
in s[10…6000]
10…*300…6000
Manual operation remains activated until the adjusted time is up or deactivated by button manually.
Device alive operation active
*no
yes
This object is used to report that device is still alive and connected to KNX line. (Heartbeat) If alive
telegram is not received, device may be defective or KNX cable can be disconnected. If parameter is
selected "yes", following parameters come up.
In operation bit
0
*1
Telegram value can be selected as “1” or “0”.
In operation send interval
1…*300…65535
Telegram value is sent cyclically according to time interval.
Transmission delay [2…255s] after bus
voltage return
*2…255
The parameter defines the behaviour of the actuator at a bus power return. The transmission delay
time determines the period between bus voltage recovery and the point after which telegrams can
be sent.
Telegram limit active
*no
yes
Telegrams which are sent by the gateway can be limited with this parameter. If “yes” is selected,
following parameters come up.
Telegram limit period
50ms…*10s…1dk
The limit period can be selected via telegram limit period parameter.
Max. number of transmitted telegram
1…*20…255
Maximum number of telegrams can be sent freely within a period.
NOTE: If the value of the object cannot be sent in the time of a period. The object is buffered for the
next period time. The buffered object will be updated if the object value is updated.

If parameter is selected “yes”, “Scenes” section will be visible in parameter titles.
Weather alarm function

If the parameter is selected “yes”, “Weather Alarm”section will be visible in parameter titles. You
can find weather alarm information under the “Weather Alarm” section.

1.Rain 2.Wind 3.Frost
1.Rain 2.Frost 3.Wind
1.Frost 2.Wind 3.Rain
1.Frost 2.Rain 3.Wind
If an alarm is triggered, the drives move into a safe position and stay in safe position until the event is
over. You can select the priority of the weather alarm. This parameter is applied for all blind/shutter
channels which are enabled for weather protection function. If more than one weather alarms occur
simultaneously, then only the alarm with highest priority will be activated. The other lower priority
alarms are carried out after highest priority alarm is completed.
Wind alarm
*disable
enable
This parameter activates the wind alarm. If the parameter selected “enable”, “Monitoring period for
wind alarm in s [0…1000]” parameter will be visible.

Monitoring period for wind alarm in s
[0…1000]
*0…1000
The telegram of the active weather station is monitored cyclically. The actuator waits for a telegram
from the weather station within the cycle time. If the telegram is not received within this monitoring
period time, actuator assumes that the weather station is broken or bus line is damaged and the
blind moves into the parameterized position.
▪0: If “0” is selected cyclically monitoring is deactivated. If the alarm telegram value is “1”,
weather alarm is activated.
Rain alarm
*disable
enable
This parameter activates the rain alarm. If the parameter selected “enable”, “Monitoring period for
rain alarm in s [0…1000]” parameter is visible.
Monitoring period for rain alarm in s
[0…1000]
*0…1000
The telegram of the active weather station is monitored cyclically. The actuator waits for a telegram
from the weather station within the cycle time. If the telegram is not received within this monitoring
period time, actuator assumes that the weather station is broken or bus line is damaged and the
blind moves into the parameterized position.
▪0: If “0” is selected cyclically monitoring is deactivated. If the alarm telegram value is “1”,
weather alarm is activated.
Frost alarm
*disable
enable
This parameter activates the frost alarm. If the parameter selected “enable”, “Monitoring period for
frost alarm in s [0…1000]” parameter is visible.
Monitoring period for frost alarm in s
[0…1000]
*0…1000
The telegram of the active weather station is monitored cyclically. The actuator waits for a telegram
from the weather station within the cycle time. If the telegram is not received within this monitoring
period time, actuator assumes that the weather station is broken or bus line is damaged and the
blind moves into the parameterized position.
40: If “0” is selected cyclically monitoring is deactivated. If the alarm telegram value is “1”,
weather alarm is activated.
4.1 Scene
The scene function of the switch actuator has an 8 bit scene object. You can define for each 64 scene
with parameter window. 8 independent values can be stored for each relay or each blind. The scene
can be specified that the relay OFF (open contact), or ON (close contact) its state for switch function.
If you use the blind, you can configure the blind height and slat position. You can save height position
for blind also slat-opening angle as scene values.
