System Schematics; Individual Control Radiator With Wall-Mounted Gas Condensing Boiler - Bosch Src 100 Rf Installations- Und Bedienungsanleitung

System schematics

5 System schematics
The following system examples give an impression of possible areas of
application for the individual control. The individual control feature can
only be used in one heating circuit. It is not possible to activate the
feature in 2 or more heating circuits at the same time. However, the
heating system can consist of several heating circuits. In this case, the
individual control feature can be used in one of the heating circuits and
the other heating circuits can be operated with other remote controls
(e.g. CR 10) or also without other remote controls.
Further configuration options (e.g. number of possible heating circuits,
compatibility of the remote controls or heating circuit modules, etc.)
depend on the components used, the system operation and the wall
hung condensing boiler or heat pump. The individual control feature is
basically "only" to be seen as a remote control in a heating circuit and can
therefore be used in a variety of ways.
CR 20 RF and individual control are incompatible and therefore cannot
be used together in one system.

If other heat generators are integrated (e.g. external heat generators
such as pellet boilers integrated via the buffer cylinder), the control type
in the relevant heating circuit should be Outside temp.-compensated
or Outside temp. with base point and not Single room-dependent.
This is because the heating curve only adapts if one of the heat
generators listed in chapter 3 is active (generates heat). In systems with
other heat sources (e.g. buffer cylinder with thermal solar integration)
and the control type Single room-dependent, there may therefore be a
delayed adjustment of the heating curve.
In general, the planning documents for the devices must be observed
when selecting the hydraulics.
