Siemens Synco™ living CE1C2740en
Building Technologies Commissioning the system 13.12.2010
--- Inactive – refrigeration demand relay not needed
(factory setting).
Via RF Relay output Qx of an RRV91… heating circuit con-
troller or RRV934 multi-controller used as a refrig-
eration demand relay.
Q1 (local) Relay output Q1 of the central apartment unit used
as a refrigeration demand relay.
Refrigeration demand DC 0..10 V
The current refrigeration demand can be transmitted to the refrigeration
source in the form of a DC 0..10 V signal.
The temperature values corresponding to DC 0 V and 10 V and the threshold
value for a valid refrigeration request can be set (see page 120).
Specify if the DC
0..10 V refrigeration demand output is used and how it is
controlled.
Main menu > Commissioning > Basic configuration
> Outputs > Refrig dem DC 0..10V:
--- Inactive – DC 0..10 V refrigeration demand output
not required (factory setting).
Via RF Universal output U of the RRV912… heating circuit
controller or the RRV934 multi-controller used as a
DC 0..10 V refrigeration demand output.
Summer operation
When the respective output terminal closes, changeover of the central apart-
ment unit to summer operation can be communicated to external components /
controllers.
Specify if a summer operation relay is used and how it is controlled.
Main menu > Commissioning > Basic configuration
> Outputs > Summer operation:
--- Inactive – summer operation relay not needed
(factory setting).
Via RF/S-mode Summer operating state delivered via:
• Relay output Qx of an RRV91.. heating circuit con-
troller or RRV934 multi-controller.
• S-mode object on KNX TP1 *.
Q1 (local) Relay output Q1 of the central apartment unit used
as a summer operation relay.
* Connection of the respective S-Mode objects of the central apartment unit to the relevant S-Mode de-
vices on KNX TP1 via commissioning tool (ETS).
