Pairing with a LightwaveRF Radiator Valve
In order to enable communication between radio
components, the devices have to be paired to one
another. Proceed as follows to allow LightwaveRF
Radiator Valves to be managed via a Room
Thermostat:
1. Set the radiator valve to LEARN mode. For more
information on this, refer to the operating manual for
the Radiator Valve.
2. Press and hold down the OK button on the Room
Thermostat for longer than 3 seconds to transmit the
pairing code.
3. "LEA" and the remaining pairing time (starting at 30
seconds) appear on the display and the Room
Thermostat transmits a pairing code.
4. When the Radiator Valve receives the pairing signal,
"ECF" appears on its display.
5. The Room Thermostat can be paired to as many
LightwaveRF Radiator Valves as you wish. Repeat the
process to pair additional devices.
