7.12.4 Priority over all controllers

It is possible to put the heating circuits of other controllers out of operation while the DHW
heating is active when the controllers are linked to one another over a device bus. The return
flow temperature limitation in the primary circuit can also be raised to the adjusted value for
Maximum return flow temperature or for Point 1 of the return flow temperature in a 4-point
characteristic when the controller is configured correspondingly. Controllers which should
operate a DHW heating with priority need to issue a DHW heating active alert. Controllers
that have heating circuits which should be deactivated during this active DHW heating alert
need to have the configuration Receive release of Rk_ for the heating circuits concerned. If
the circuit is just a DHW circuit which should influence one or more heating circuits, they
need to be given the identical register number. If there are several DHW circuits in the sys-
tem, selected heating circuits can only react to one or other active DHW circuits by assigning
different register numbers.
If a secondary heating circuit with a valve should be put out of operation, the heating circuit
valve concerned is closed; the heating circuit circulation pump remains in operation.
If a secondary heating circuit without a valve should be put out of operation, for example, in
system Anl 2.x, just its heating circuit circulation pump and not the primary circuit Rk1 is put
out of operation by using the configuration Receive release of Rk1.

7.12.5 Connecting a TROVIS 5570 Room Panel

A TROVIS 5570 Room Panel (accessory) can be connected to the TROVIS 5579 Controller to
measure the room temperature and for remote operation of a heating circuit. The room
panel enables direct access to the operating mode and controller time settings as well as to
all relevant parameters of a heating circuit. Additionally, the room temperature, the outdoor
temperature and, if applicable, other data points can be retrieved and displayed.
The room panel is connected to terminals 27 to 30 as illustrated in Fig. 12.
