After power is applied, the thermostat resets and all LCD segments flash, indicating
that the reset was correct. After the reset, which takes about 3 seconds, the
thermostat is ready for commissioning by qualified HVAC staff.
If all DIP switches are OFF, the display reads "NO APPL" to indicate that
application commissioning via a tool is required.
Each time the application is changed, the thermostat reloads the factory setting for
all control parameters, except for KNX device and zone addresses!
Connect the Synco ACS or ETS3 Professional tools to the KNX bus cable at any
point for commissioning:
KNX
X1 M U1 D1 GND CE+ CE-
Y10
Y1 Y2
ACS and ETS3 require an interface:
– RS232 KNX interface (e.g. Siemens N148 / UP146 / UP152)
– OCI700.1 USB-KNX interface
An external KNX bus power supply is required if an RDG is connected directly to a
tool (ACS700 or ETS3) via KNX interface.
The thermostat's control parameters can be set to ensure optimum performance of
the entire system.
The parameters can be adjusted using
– Local HMI
– Synco ACS
– ETS3 Professional
Parameter and application download with ETS3 will be implemented later.
The control parameters of the thermostat can be set to ensure optimum
performance of the entire system (see section 3.11, control parameters).
 The control sequence may need to be set via parameter P01 depending on the
application. The factory setting is as follows:
Application
Single duct, Single duct with H/C coil
Single duct with el. heater, Single duct with radiator
