Building Technologies 2015-12-23
The programming LED shows the operational status of the room controller as
follows:
Green flashing
OK, device is in operation
Red ON
• Addressing mode (ACS / ETS)
• Fault
Orange / green flashing
Parameter download
OFF
• No supply voltage
• Fault
• Service LED disabled by software

The programming pin is used to identify the controller in the commissioning phase.
Pressing this pin causes the red programming LED to light up and remain on until
identification of the controller is complete.
Once the programming pin has been pressed, the tool overwrites the hardware
address in the room controller.
Terminal covers (RXZ20.1) are available as an option, to protect the connection
terminals from physical contact and dirt. The service LED remains visible when the
terminal covers are in place, and the programming pin can be operated with a
pointed implement. The cable is connected to the room controller by breaking out
the perforated cable entry guide.
