Ledrak is correct. The 06002M model is not compatible with the 00822A2 model. You would need sensor model number 00606TX. Also provided in the link that Ledrak has given. To sync up the display and outdoor sensor you would follow the hard reset procedure below. If you have any further questions please let us know. Thank you.
1.Bring both the sensor and display unit indoors and remove batteries from each.
2.Reinstall batteries in the sensor unit first and watch for the red light to flash
3.Reinstall batteries in the display.
4.The outdoor temperature should now be displayed.
