TR016 are extremly hard to find these days. We have not had them for several years!
Most showers from a similar line to those we supply parts for use the MK series of control pads (MK117, MK220, MK117u etc)
only real option is to look to change the pad to an available type.
This however does come at a greater cost, since you cannot 'just change
the pad' The electonic contol unit and steam generator must all be of the
same type to enable communication to be passed.
Additionally, the choice of pad will require you to modify the current 'hole' that the TR016 occupies.
steam genertor and electronics come in two options (slimline) which is
the two parts separated and joined via Data cables or as a combined
(both parts in one box) Both are identical, the variation is simply that
the slimline ones are designed to install to the back of the tower
panel (behind where the valve is) in Low Step tray style showers, whereas, Tub
based models can accomodate the combined unit underneath.
This would also apply to anyone looking for control panels that we do not show and therfore do not have available.
