The recommendation on the previous page is particularly important in relation to a
network with a large number of RX... room controllers.
In a line containing up to 62 RX... room controllers, an RMB795 central control unit
is used as a "collector". The area/line couplers are set to "Normal (route)".
The heating and refrigeration distribution zone in each RX... room controller is con-
figured with a zone address in the range 1...15 (data communication within the line).
The heating and refrigeration distribution zone in each RX... room controller is
configured on the consumer side with a zone address in the range 16...13 (data
communication via area/line coupler).
The heating/refrigeration demand from the RX... room controllers is transmitted by
the "collector" to the RMH primary heating and RMU primary cooling controllers.
