Sorry to hear of your disappointment on this occasion. From the order details regarding your purchase, you purchased this standalone digital shower controller from our website spare parts section. Being a relatively recent product to market, we would expect demand for spare parts on our digital shower to be very low currently, as any product related faults would be covered under the product's 5 year guarantee at this time.
From what you have described, it would seem that you are looking for a complete digital shower unit, which would require the combined purchase of both the controller and the mixer unit, which makes the shower operational. Complete digital shower units can be found in the 'Our Range' section of the Triton Showers website, as well as through many Triton stockists in trade and retail.
We hope this helps to clarify why the part you purchased may not be fully to your requirements in this instance. Should you wish to return the controller or enquire about ordering the accompanying mixer unit, please contact our Customer Service team or email online@tritonshowers.co.uk. Kind regards, James.
