Hi Folks,
I`ve a Ferroli Optima 700 boiler that cut on and off before the radiators were at their max temp.
Someone here had suggested on another post swapping leads to the thermistors and on trying it, the gas stayed on longer with the radiators much hotter.
I`ve just renewed one of the thermistors - as you look at the boiler, it`s the one on the back pipe, extreme left and the wires to it say radiator sensor - but the gas still cuts out early. Swapped the leads around again and the gas stays on longer.
Are both thermistors the same?
Also, when refilling the system cold, should it be to 1.5 bar?
Thanks,
Stu
