Setup and operation guide for the X10 PRO HR12A RF Handheld Remote — pairs with the TM751 RF Base Transceiver for whole-home wireless lighting and appliance control.
The X10 PRO HR12A RF Handheld Remote works with the TM751 RF Base Transceiver to extend X10 remote control capability around the home. Plug the TM751 Base Transceiver into any outlet, and the HR12A gives wireless control of any electrical device connected to an X10 Receiver Module — no line-of-sight required, since it uses RF instead of infrared.
Nearly all residential homes are wired split-phase — each 120V phase is not directly connected to the other. If an X10 Receiver doesn't respond to a remote Controller after installation, check that the breaker serving the Receiver is on the same phase as the Controller. If not, either change the breaker to the opposite phase, or install a Phase Coupler to improve remote communication throughout the home (see x10pro.com > Technical Support > PLC Troubleshooting).
Once installed, press the ON/OFF button corresponding to a specific module to operate it. For dimming modules, press Bright or DIM after the initial ON command to adjust intensity.
To print a new label for the HR12A channels, run ActiveHome Pro software: File > Print > Type of Report > Controller Labels. ActiveHome Pro is available for download at x10pro.com under Tech Support.
As with all RF transmitter devices, electrical fields, metal doors/door frames, and appliances can reduce transmitted signal strength. Relocating the TM751 RF Base Transceiver may improve reception of signals from the HR12A.
