Hi. I have recently noticed an odd problem.
Boiler runs perfectly when CH and/or CH/HW demands.
Problem occurs when ONLY HW demands.
Boiler seems to exceed required set temperature (by 2 Degrees) within 60 sec and turns itself off. It continues to start and stop in the manner indefinealtely. It continues to do so pretty much until CH comes on.
I have range rated it to 18KW still same problem.
It seems when the boiler fires up it fires up on maximum and doed not modulate down quickly enough.
Any ideas?
Regards
Vin
