Can the frequency of the remote be changed if I have something else activating the fireplace?

No. The frequency of the remote control cannot be changed without special equipment, which is not readily available to homeowners and/or service companies. Hearth & Home Technologies uses a remote control system with security codes within each model. These security codes are burned into the transmitter of each model and cannot be changed. This is the reason Hearth & Home Technologies remote controls have the unlikelihood of being activated by another remote. If there is more than one Hearth & Home Technologies remote control at a home it is important that each hand-held transmitter has had the “learn” function activated to its designated receiver. If one hand-held transmitter was used in the “learn” activation for both receivers only one hand-held will function.
