Sustained pressure (>5s) on the button of one of the existing room units.
The receiver will delete this room unit from its device list and then switch to
installation mode.
Insert the batteries in all the additional devices to be installed (or remove insulating
strip); the devices will switch to installation mode.
The receiver recognises all newly connected room units and adds these to its device
list.
The room unit on which the button has been pressed, is deleted from the device list
and therefore has to be reconnected. To bring it off load and set it to installation
mode, remove the batteries for at least 30s.
Caution: Wait 4 minutes before changing any further links.
For this purpose you need a special diagnostic plug (see
Diagnostics,
below). Insert
it and press the button on the plug for >5s. This will delete the entire device list from
the receiver and then bring it to the "Normal mode" with an empty device list.
To re-commission it, shortly bring the receiver off-load.
Then follow the procedure under
Establishing communication for the first time
.
Additional notes:
•
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
à
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.
