Power supply selection for RDG200KN
The RDG200KN can be powered either on AC 230 V (default) or AC 24 V.
To select the correct power supply, use the power switch on the rear of the device.
Note:
The outputs (triacs and relays) follow the main power supply, either AC 230 V or AC 24 V.
The device will be damaged if set to AC 24 V, but powered on AC 230 V.
Applications
The RDG2..KN room thermostats support the following applications, which can be
configured using the DIP switches on the rear of the unit or via the commissioning tool.
Remote configuration
Set DIP switches 1…5 to Off (remote configuration, factory setting) to select an application
via commissioning tool.
