Mend Ravenheat CSi 150 CH Boiler Central Heating Fault

Ravenheat CSi 150 CH problem?

Hi My HW works fine, but when i put the CH system on the rads warm up nice and hot the boiler stops as expected but it waits until the radiators are near cold before it cuts back in again. The boiler does not trip out or show any fault codes. Checked the return temp at the boiler by hand and its the same as the rads just warm before the boiler cuts back in again and then you cant keep your hand on it.
