1.3 Pair the outside temperature sensor with the radio module
Each outside temperature sensor is given a unique identifying number in
the factory, which enables the radio module to recognise it The identifying
number is transmitted to the radio module by the pairing sequence.
1. Refer to the assembly instructions for the radio module.
1.4 Test radio reception
Important
Reception problems may occur depending on the construction
materials used in the house (thickness of walls or floors, type of
materials used).
When the position of the outside temperature sensor has been decided
upon, carry out a test to ascertain whether radio reception between the
sensor and the radio module is adequate:
1. Check that the heating generator is switched on.
2. Position in the place selected for installation of the sensor. Press the
button on the outside temperature sensor.
3. Check that the light on the radio module flashes every 3 seconds. If
this does not happen, the reception is not good. Select another
place for the sensor and carry out the test a second time.
4. To exit this mode, press the button on the outside temperature sen­
sor. The mode is exited automatically after 5 minutes.
1.5 Fitting the outdoor sensor
