Hi,
We have the following system:
Ideal Icos HE12 boiler
Danfoss CP715 control panel & thermostat
Heatrae Sadia Megaflo unvented indirect cylinder
Grundfos UPS 15-60 pump
Danfoss HPA2 valve (switch set to automatic - what does this even do?)
Essentially everything's working ok except that the pump doesn't shut off any more. Whilst it's still running, the boiler's LCD reads "C" and the LEDt is flashing which the boiler's manual says it does "during ignition".
I'm not averse to calling out a pro, but I just wondered whether there's any troubleshooting I can do myself?
Thanks!
