Hi All,
Having a problem with a solar 2000 boiler. HW works fine (with the occasional lockout), But the CH side ignites and flames die out before they can heat anything (with the thermostat set in any position).and the boiler repeats the same ignition cycle over and over. There's no room t/stat so it can't be that. resetting it doesn't work, but if I adjust the potentiometer to test and bring it back to winter or summer setting it stays on and heats the rads without problem - even reignites when the temp has dropped enough for it to kick in again. anyone had or heard of a similar fault?
TIA
Keef
