BACnet object description 

(continued) 

 

Object Name 

Object Type / Instance 

Description 

Values 

Default 

MIN_STPT_[n] 

Analog Value  

[n*100+1] 

Minimum limit (position or flow) in % 
 
Attention: Changing the limit may result in 
malfunction of the device. 

0…100 

MAX_STPT_[n] 

Analog Value  

[n*100+2] 

Maximum limit (position or flow) in % 
 
Attention: Changing the limit may result in 
malfunction of the device. 

20…100 

NOM_FLOW_[n] 

Analog Value  

[n*100+3] 

Nominal volumetric flow (or pressure) 
 
The unit depends on the node type: 
[m3/h] for VAV controllers 
[Pa] for VAV controller in STP mode 
[l/min] for EPIV units 

0…65535 

 
 

Connecting the PC-Tool for parameterisation of the MP/MFT(2) actuators 

 

The MP network can be scanned, actuators can be addressed and actuator-specific parameters 
(e.g. running time) can be readily adjusted with the Belimo PC-Tool. 

The PC -Tool can be accessed directly on the MP-Bus via the RJ12 socket of the 
UK24BACMOD. The Gateway recognises the connected PC-Tool automatically and stops 
communications with the MP drives.
