Samson TROVIS 5575 - Synchronizing the Clock; Priority over All Controllers

Functions
WE Configuration
Receive value AF1 0
1
CO7 -> F07 - 1
Register no. / 1 to 4
Receive value AF2 (receive an outdoor temp.
independent of Rk1)
0
2
CO7 -> F09 - 1
Register no. / 2 to 4
Note!
The register no. for the outdoor temperature AF1 or AF2 must be the same for the sending
and the receiving controller.
7.11.3 Synchronizing the clock
One controller in a system of coupled controllers should perform the Clock synchronization
function. This controller sends its system time once every 24 hours to all other controllers via
the device bus.
Regardless of this function, the system time of all controllers is adapted immediately when the
time setting of one controller is changed.

7.11.4 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. Control
-
lers which should operate a DHW heating with priority need to issue
DHW heating active
alert. Controllers that have heating circuits which should be deactivated during this active
DHW heating 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 cir
-
cuits, they need to be assigned with the identical register number. In the case that there are
several DHW circuits in the system, 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.
