First time on list and I have checked for previous threads on this so apologies if this is already been covered somewhere.
I have an extension with a new boiler a Wochester Bosch Greenstar24 Ri. (2007).
The thermostatic system is a Drayton Tempus 3 that came with the original house.
Everything fine until this winter, the outlet pipe froze but recognised the problem and cleared. So far ok.
Tonight the weather was chilly but no frost, but the CH would not fire up. The HW goes fine and everything works.
If I run the CH, it looks like it will start, the thermostat clicks over, but the boiler will not fire up no green ignition light.
I change over to HW and everything does as it should, click over boiler fires up and the green ignition light goes on and stays on.
Any ideas on the problem? There is no fault code on the boiler.
Could the problem be with the Drayton Tempus three sytem? If so, where is it? The HW works, but not the CH.
Any help would be appreciated. Do I need to replace the Drayton or is there something wrong between the boiler and the drayton? If so, where? As this has worked for over 3 years.
