Milano

The Spaform company has gone out of business, I have tried searching the web for a manual/operating books to no avail,the tub is 10 years old now and served me well,and have done numerous repairs myself over the years(I am an engineer by trade)Really don't want to buy a new tub,but the thought is crossing my mind "Is it time to come into the modern world with sound and LCD displays" hmmm deep thought needed.

Looking for some advice on my Spaform Milano, the temperature is at 40.5 degrees constant with the "heat" light on and I cannot lower the temperature, I am thinking the thermostat is cooked but have no operating/instruction manual,anyone know where I may get these manuals from????
