Testing Radio Connections; Wiring Test - Siemens Synco 900 Mounting And Commissioning

Testing radio connections

The radio connections between the central apartment unit and the
following devices can be tested at any time:
• Room temperature sensors
• Room units
• Radiator control actuators
• Heating circuit controllers
• RF repeaters
• Meteo sensors
Press briefly the binding or the multifunction button on the device. If
the connection works, the central apartment unit delivers 3 succes-
sive bleeps. If the central apartment unit is on the default picture or
on one of the info pages, an additional window with the respective
device information appears. The window can be hidden again by
pressing the Menu/ok or the Esc button.

Wiring test

On completion of the configuration and connection of the devices, it is
recommended to make the wiring test with the connected compo-
nents.
The current states of the inputs are displayed:
• The current temperature value at the sensor inputs
• 0 / 1 with input contacts (0: contact open, 1: contact closed)
During the wiring test, each of the outputs can be set to a certain
value:
• 0..100 % (corresponding to DC 0..10 V) for heat demand
DC 0..10 V
• Off / on with relay outputs (off: relay contact open, on: relay
contact closed)
During the wiring test, the application is not active. Safety-
related functions are switched off. Switch the relay outputs off
again.
You find the wiring test for the different inputs and outputs on the
following menus:
DHW (DHW sensor, DHW pump / valve and electric heater):
Main menu > Commissioning > Wiring test > DHW
Switching group relay (switching group 1 – 8 ):
Main menu > Commissioning > Wiring test > Switching group relay
Faults (fault input 1...4, fault outputs 1 and 2):
Main menu > Commissioning > Wiring test > Faults:
