Terminal covers (RXZ30.1) 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 button can be operated with a
pointed implement. The cable is connected to the room controller by breaking out
the perforated cable entry guide.
