7.11.1 Setting of Bus addresses
The addresses of the individual devices must start with “ 1 ” (= master device) and be numbered
consecutively.
It is recommendable to number them according to the stalls.
A maximum of 32 network users can be connectedto each other.
Information
•
The ventilatoin computer where the supply air temperature sensoor is to be connectedalways
has to have the address 1(diplay- - - -)! It is the “ Master ” .
•
The collective fault relay is situatedat the “ Master ” (compartment 1). It is not possible to change
it. In central exhaust air installations, formation of sums is effectedat the “ Master ” .
•
It is not allowed to enter one address twice!
7.11.2 Operation with only one control unit (Stand-Alone)
If the ventilation computer is usedas a stand-alone control unit, it has to be usedas “ Slave ” unit (bus
address has to be between “ 2 ” and “ 32 ” ), factory setting “ 32 ” ).
In order to be able to detect the supply air temperature, the parameter Supply air temp. must be
programmedto
|
E2
|
in IO Setup (at the factory
|
Bus
|
). The supply air temperature sensor is
connectedto terminals “ E2 ” - “ GND ” .
