hello Dave thanks for your help tony

round the by-pass,and up the vent, where else. the boiler tubes must still be dirty,another clean-out. i live in a very hard water area and have in the past refilled with softened water, is this a good or a bad thing :?:

hello thank you for your answer. can the overrun pump time be increased and how. tony

i need to lower the temperature at which the over-run pump cuts off, at the moment it is 76c ,which i think is too high, can this be adjusted on the user interface board. i have replaced the return thermister.

can this be done on the user face board tony

i need the instructions to setup the user face board, ie. 4 pots. and 4 switches. i need to alter the pump over-run time and cut off tempreatur
