4 Pairing an outside temperature sensor
The pairing must be done in the boiler room on first
initialisation.

5 Cancel pairing
To cancel the pairing on all circuits and outside temperature sensors,
press the button on the boiler's radio module for 10 seconds (until the
light goes off and then flashes).

Each outside temperature sensor is given a unique identifying
number in the factory, which enables the boiler's radio module to
recognise it. This identifying number is transmitted to the boiler's
radio module by the pairing sequence described below.

- Switch the boiler off and switch back on.
- If the problem persists, contact the fitter. The boiler's radio module is damaged.
- No remote control or outside temperature sensor has been paired with the boiler's radio
module.
- If the rapid flashing does not stop 10 seconds after being switched on, a radio remote
control is paired with a circuit that already has a wire remote control. Re-pair the radio
remote control with another circuit or connect the wire remote control to another circuit.
- The boiler's radio module is in pairing mode with a radio remote control or an outside
temperature sensor. This mode remains activated for a maximum of 2 minutes.
- The boiler's radio module has communicated with the radio remote control or an outside
temperature sensor.

Press the button on the boiler's radio module using the tip of a
ballpoint pen. The light on the boiler's radio module comes on.
Press the button on the outside temperature sensor. The light
on the outside temperature sensor comes on. The light goes
off briefly every 3 seconds when the boiler's radio module picks
up the signal from the sensor transmitting information on the
outside temperature.
After a few seconds, the light on the boiler's radio module goes
off. The light comes on briefly every 3 seconds to confirm
reception of the outside temperature. To exit the pairing mode,
press the button on the outside temperature sensor.
The boiler's radio module exits the pairing programme
after 2 minutes. The outside temperature sensor
automatically exits the pairing mode after 5 minutes.
