The programming LED shows the operational status of the room controller as
follows:
Green flashing
Red ON
Orange / green flashing
OFF
Other patterns
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.
If there are no terminal covers fitted, the programming pin may be operated only by
a qualified electrician.
The adjacent terminal may be a live mains voltage conductor.
Terminal covers (RXZ20.1) are available as an option, to protect the connection
terminals from physical contact and dirt. The programming 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.
