ferroli tempra 18 problem

[mmalone]

dont know much about these boilers but this one the pump etc runs every once in a while without any demand.. The boiler doesnt fire so my thoughts are possibly a frost stat ? do these have built in frost stats ??


all other controls are ok on an s plan system

I don't no the specifics of that boiler but some do run the pump once every 24 hours to prevent it sticking.

this is like every 15 minutes !!

Had a quick look at the M.I'S and the central heating sensor seems to have built in frost protection so pretty sure thsi will be the problem...
