We would prefer setting up the hot tub before your stay as operating it is quite complex. Please use the hot tub when clean and don’t forget to cover it when not in use to avoid loosing too much energy (this can be quite significant as there is a 3kW heating).
The hot tub needs to be off when not in use to make filtration and heating work automatically. The keyboard automatically locks itself quite fast and you need to press the lock button to be able to use it.
There are two water pumps (1 and 2) for different seats in the hot tub which can be switched on separately. There is also a button for the air blower for bubbles and another one for the light (you can choose the color by multiple pressing this button).

Reading the manual in French or some hints in English might help. Please be careful when operating it and ask for help if there are any doubts.
