Manual for software version U3.0 – 01 (22-06-2017)
This manual describes the connection of the comfort air cur-
tain SR, the industrial air curtain model IndAC
heater model NOZ to the communication protocol Modbus
2
RTU and its use.
For a possible connection to BACnet, the manual describes
the installation of a gateway which makes communication with
BACnet possible. The contents of this manual also apply to
BACnet, unless otherwise specified.
For IndAC and NOZ , it is the case that only units with an
2 2
automatic control (type Auto) can be connected to a commu-
nication protocol.
To use this manual, you must have general knowledge of the
communication protocol ('Modbus RTU Slave' or 'BACnet').
This manual is not a guide to this protocol.
For more information about Modbus, please refer to the spec-
ifications and guidelines that are available on the website of the
Modbus Organization: www.modbus.org.
