•
The room unit starts in installation mode each time batteries are inserted (after min.
30s off load)
•
When there are no room units in its device list, the receiver starts in installation mode
when the power supply is connected. It scans for installation signals for 3 ½ minutes,
and identifies all room units in installation mode within its receiver range
•
The first 5 room units identified are entered in the device list of the receiver
•
For each receiver, a delay must precede the process of establishing communication,
as the receiver can also pick up signals from other room units in the vicinity
 Wait at least 4 minutes between each new installation sequence
•
A Receiver with at least one room unit in its device list will not switch to installation
mode after a power failure, but continue normal operation with the associated room
units.
•
Connecting the receiver to the power supply (power ON) when the device list is
empty (snap-mount RXZ90.1 receiver on mounting plate)
•
Connecting the controller to the power supply, when the receiver is connected to
the controller and its device list is empty
•
With fewer than 5 room units registered, connecting the diagnostic plug to the
receiver and pressing the button briefly ( < 1s)
•
Plugging the RXT20.1 service terminal into the receiver with an empty device list,
and pressing the service pin on the RXT20.1 >4s
•
Sustained pressure (>5s) on the button of an existing room unit. The receiver will
delete this room unit from its device list and then switch to installation mode
The process of establishing communication (receiver status) can be monitored by
connecting the diagnostic plug to the receiver.
The plug can be assembled in-house or ordered from your national Landis & Staefa
office. It is an aid for the service staff and cannot be purchased normally.
