COV_MODE 

Multi-state Value  [1] 

Setting of the COV mode 
 
If COV is enable, changed values will be 
transmitted as broadcast (local or global). 
The property

must be 

adjusted accordingly for

NODE_TYPE_[n] 

Multi-state Value  [n*100+0] 

Actuator type; the allocation may deviate 
from the basic category with some actuators. 
 
Note: In the event of a communications 
interruption, the Gateway will discard the 
affected actuator after 10 seconds and reset 
the actuator type to 0. Monitoring of the 
actuator is thus accomplished preferably 
with this object. 
 
Each MP node has an unambiguous series 
number (e.g. 00839-31324-064-008). This 
number is show in the property

Setpoint for actuator setting in % 
 
The default value can be parameterized with 
property 

Relinquish_Default

.  

 
In the case of actuators for fire dampers, the 
control must be accomplished through 
override control (see OVERRIDE). 

0…100 

OVERRIDE_[n] 

Multi-state Value  [n*100+1] 

Overriding the setpoint with defined values 
 
The default value can be parameterized with 
property 

Relinquish_Default

 
For fire dampers: 
Due to safety considerations, the only 
override values permitted in the case of 
actuators for fire dampers are OPEN and 
CLOSE.  
The operating position (OPEN) must also be 
repeated within 120 seconds. If the override 
command is not renewed, then the Gateway 
will move the actuator into safety position 
(

Relinquish_Default 

is not writable).
