Control three X10 receiver modules using the X10 PRO 4-Button Keypad (3 Address & 1 Dimmer). This keypad attaches to the front of an X10 PRO Wall Transmitter Base Module (XPT, sold separately) to create a custom X10 wall switch. Once installed, the keypad sends On/Off and Dim/Brighten commands to three sequential X10 unit codes.
When used with the transmitter base, the X10 PRO 4-Button Keypad (3 Address & 1 Dimmer) controls three X10 receivers by running the Unit Codes in sequential order. In other words, if you have the dials on the transmitter base set to House Code B and Unit Code 4, this keypad will control the X10 receivers set
