Operation with several address settings
Your heating system can be made up of several heating
circuits. Heating circuit 1 is usually controlled by the base
module in the boiler (WRS-CPU). Additional heating
circuits are controlled separately by the extension module
(WRS-EM).
A separate operating unit can be assigned to each heating
circuit and/or module.
However, it is possible to program all heating circuits with
one operating unit by selecting the relevant address.
7.1 Unit selection for several heating circuits
This allows programming and display of all Bus
participants. The selection switch for type of operation, the
presence/absence button and the room sensor are not
active. Likewise the direct setpoint adjustment (child lock
setting possible).
With this setting the room temperature will not be
displayed in the Info level. However, the display shows all
other values as shown at address 1.
Note: Often the data of the selected module has to be
read if parameters are to be changed (heating
engineer level, parameter 910 ➩ “0” or “2”), to
ensure that current data is available. After every
alteration has been made which needs to be
backed up, the data has to be written(heating
engineer level, parameter 930 ➩ “Yes”). If this
procedure is not followed some parameters may
be transferred incorrectly or they will not be
changed in the modules.
7.2 Special feature: Address “0” (address setting in heating engineer level of WRS-BE)
It is possible for all modules to be monitored by a janitor.
The operating unit has to be unlocked by the heating
engineer in heating engineer level,
parameter 910 ➩ “0” or “2”.
7.3 Central operating unit (control point) address 0, 2
