Correct. Transceivers only have the house code. Each switch or module has the house code AND unit codes 1-16. I've never used a remote like you are using. Not really sure how you would operate a switch with a unit code higher than 9. Have you ever seen a palm pad?. If you just need the X10 commands they are much more convienent to use.
