LK Repeater ICS

 
LK Repeater ICS is used to increase the transmission distance between the LK Room Thermostat ICS RF and
the LK Receiver unit ICS-RF.
The repeater consists of a radio link with receivers and transmitters. A transformer that plugs into a 230V outlet
comes with the repeater. The repeater is placed between the outer thermostat and receiver. Mount the repeater
so that the antenna is vertical. The set-up may contain up to 4 sets of repeaters.

Adaptation of LK Repeater ICS

The repeater is connected as follows:

1. Switch the repeater off (if it is powered up).
2. Press the L key for at least 3 seconds on the receiving device. The L-LED should light green.
3. Connect the repeater to a 230 volt outlet.
4. Wait until the repeater starts flashing orange.
5. Confirm by pressing the L key.
