1.1 About these instructions
Please read and follow the operating instructions, in particular the safety information
contained therein. Keep them available next to the boiler.
These operating instructions include important information about operation, electrical
connection and troubleshooting. The parameters shown depend on the set boiler type
and the system configuration!
The constant further development of our products means that there may be minor
differences from the pictures and content. If you discover any errors, please let us know:
1.2 Safety information
DANGER
When working on electrical components:
Risk of electrocution!
When work is carried out on electrical components:
rAlways have work carried out by a qualified electrician
rObserve the applicable standards and regulations
ÄWork must not be carried out on electrical components by unauthorised persons
Installing the RBG 3200 | 2
B0640421_en | Operating instructions Control Panel RBG 3200 5
2 Installing the RBG 3200
take cable through
rFit the holding frame as shown at the desired position in the room using the
anchors and screws provided
ÄThe large grommet must be on the left!
ÄIt is recommended to install the device above a flush-mounted socket so that
there is plenty of space to stow away the bus cable.
2.1 Connecting the bus cable
For the bus connections between the individual modules, cable type LIYCY paired
2x2x0.5 should be used. The connection to the 5-pin plugs should be carried out
according to the following diagram:
Braided shield
white
green
yellow
brown
Braided shield

2.2 Setting end jumpers
NOTICE!To ensure smooth running of the bus system, the jumper must be set
on the first and last module.
When using a bus repeater, the two galvanically separated sub-networks must be
considered separately. The jumpers for each network must be set on the first and last
module.
2 | Installing the RBG 3200
6 B0640421_en | Operating instructions Control Panel RBG 3200
End jumper not set End jumper set
If the contacts at the base of the end jumper are not bridged (image left), it is referred
to as “not set". In this case there is no bus termination. If the contacts are closed
(image right), the end jumper is set and the bus connection is terminated.
2.3 Setting the module address
You must set the required order with the module addresses for the RBG 3200 (display
module). The standard boiler comes with a display module (boiler display) with the
address 0 (except S3 Turbo with S-Tronic controller). If you, therefore, install an
additional display module, set it to address 1 so that the standard hydraulic system
settings do not need to be reconfigured. Set all further RBG 3200s module addresses
in ascending order (2 to 7).
Important! Only set the module address when the device is disconnected from
the power supply!

2.4 Initial startup
NOTICE
You should have the initial startup carried out by the authorised heating engineer from
Froling customer services.
Once you have connected the device to the power supply and switched on the main
switch, the start logo will appear and the control will perform a system check.
After the system check the basic display will appear.
The default basic display provides information about the two main parameters,
however it can be customised to the user's individual requirements.

If the outside air temperature falls below this value in setback mode, the heating circuit pumps
and mixing valve are activated.
Frost protection temperature
If the room temperature or the flow temperature is lower than the set value, the heating circuit
pump will be switched on and the heating circuit mixer keeps to the maximum heating circuit
flow temperature that is set.

From which temperature at storage tank top should the overheating protection be
activated?
If the temperature at top storage tank exceeds the set value, the heating circuit is activated
regardless of mode (boiler, remote control) and set heating times. The flow temperature is
controlled to the value set in the parameter “Flow temperature SP at outside air
temperature of -10°C”. The function will remain active until the value falls below 2°C.
Recommendation: The overheating protection should be assigned to a high temperature
heating circuit (e.g. radiators).
