On top of the UH8-RF, there should be a sticker filled out by the engineer, if it has not been filled out and you do not have the pairing information then the UH8-RF would need to be opened up.
If in doubt, get an electrician to do this. The wiring centre would need to be opened by removing the two screws to the left and right and front panel opened. Make sure power is off. Also do not touch the circuit board.
Once the panel is open, on the top of the wiring centre you will see two small rotary dials.
Both the numbers are the channel number. Therefore in this example as both Tens and Unit dials are pointing to 9, the channel number will be 99.
This will therefore apply for every neoAir that will connect to this wiring centre. Set and make a note of the two numbers. These will be the large numbers when you go into the neoAir P2 settings. The small number in P2 will be the zone number, then you have the choice of RA for radiator or UF for underfloor heating.
