4.XX Dock for wireless remote P/N 78504. Wireless Remote, Dock and Control box must all have the same platform code, ( i.e V4.XX), these are not interchangeable with previous versions.
Note 1: Because the wireless remote and docking station are installed as a pair and often fail at the same time, it is recommended to replace the wireless remote (78504) when replacing the docking station.
Note 2: When purchasing the dock only and if your spa was made prior to 2019, you will need to update the software of your control box and remote. The control, remote, and docking station must have matching software (V.4).
