Hi, My parents have a Baxi Solo 3 PF 50, It will only start to fire when the flow temprature has dropped to about 25 degrees C and then will keep firinging for about 1/2 an hour when the flow temprature reaches
55 degC. The controls are calling for heat and the boiler on neon is lit, the overheat neon is never lit. The fan and other neons do not come on untill the boiler fires. I do notice a clicking sound like a relay when rotating the temprature control on the boiler, but it still doesn't fire. The temprature control is normaly left at max.Any clues?
Thanks
