Hi,
Just moved into a new house, and I'm having trouble with the CH system. I'm no expert on these, so please excuse any vagueness...
The boiler / CH / HW work fine when both set to timed on the controller, plenty of Hot water, and Radiators get hot.
If I go to switch the CH on by itself, outside the timer, nothing happens. Boiler stays on the pilot light, radiators remain cold.
I had a play about, and found that if i move the lever on the automatic 3 port valve (above the pump) to MANUAL, the CH then works, until the lever resets back to automatic (resets over night after CH switched off). The CH then stops working in stand-alone mode again, until i move the lever.
Ideas? Knackered valve? There is resistance in the valve when I move it to Manual (feels like a servo), and it does reset, so is it the valve or something else?
