UK24LON

Typical applications of the UK24LON

VAV  air  volume  controllers  for  supply  air 

and exhaust air employing VAV-Compact 

(LMV-D2-MP,  NMV-D2-MP  or  SMV-D2-

MP)  motorised  actuators  can  be  linked 

together via an MP-Bus. 

The  VAV  devices  and  the  sensors  con-

nected  to  them  (presence  and  tempera-

ture  sensors)  are  linked  to  L

ON

W

ORKS

®

  

through a UK24LON unit (MP/LON Gate-

way). The UK24LON provides the actua-

tor  functions  and  sensor  values  to  the 

L

ON

W

ORKS

®

  network  via  standardised 

network  variables  (SNVT).  The  actuator 

functions and sensor values can be link-

ed  via  the  SNVTs  to  the  IRC  individual 

room controller, which takes on the cont-

rol tasks for the individual room.
