hi dont know if any one can help.Having probs with boiler works fine when the temperature is turned down low but as soon as we turn it up to the auto position it switches of .We switch it of at the wall turn temperature down again turn on and it runs fine any ideas?
 
Hi, they're is two temperature control knobs and a main control knob.

Left knob = hot water temp.
Middle control = ch/hw, off/reset, hw only.
Right control = heating temperature.

Which knob are we talking about here first, i am assuming the ch/hw?
Also when you say when you turn it up to the auto position it switches off, does it not come back on? does it show any red lights?

Please explain things a little better, then i can try help you further.
 
its the right control heating temperature goes to a red light if we turn it straight up to the auto ,we have to have it turned down so the rads come on about hand hot temperature
 
Get a qualified gas engineer out to test the pressures on max and min and the inlet pressures, also to check the ntc primary sensor.
