whilst the heating has not been on several times a day there is a noise in the downstairs radiator as if the pump has come on this only lasts for a couple of seconds.Is the boiler programmed to do this so the pump does not stick it is a 28i junior.

not sure on model but yes alot of boilers are programmed to spin the pump for that reason every so many given hours.
