Spaform SF273 Touch Panel
Friday, 7 October 2016  |  Chris

This panel has really updated the look of my ageing hot tub and I'm really pleased with it. The only criticism would be the fact that only the display panel is illuminated and not the actual buttons that operate the functions. This makes it difficult to see what selections you are making in terms of Jets 1/2, Blower, Light, etc
