If more details are required about parameters, refer to basic documentation P3174.
To re-load factory settings for all parameters, set parameter P71 to ON. Restart the
thermostat after reset, all LCD segments flash, indicating that the reset is correct.
3 seconds later, the thermostat is ready for commissioning by qualified HVAC staff.
The room thermostats are delivered with a fixed set of applications. Select and
activate the relevant application during commissioning using one of the following
tools:
- Local DIP switch and HMI
- Synco ACS
- ETS5
Connect the Synco ACS or ETS5 tools to the KNX bus cable at any point for
commissioning:
ACS and ETS5 require an interface:
- Ethernet/LAN KNX interface (such as Siemens N148 / N146 / N152)
- OCI702 USB - KNX interface
An external KNX bus power supply is required if an RDF800KN... is connected
directly to a tool (ACS or ETS5) via KNX interface.
