Good evening, it may be your radiator(s) are not balanced, and therefore the water isnt circulating fast enough to warm them before the thermostat temp is reached, the radiators which are cold do they have a thermostatic valves on them?
With regard to why the thermostat goes off even when the desired temp hasnt been reached could be a sign of a fault thermostat, does the thermostat show the wrong temperature (eg saying the room is 21 degrees when actually its 18)?
Good evening, I havent heard from you so wanted to follow up to see if you still require assistance for your query?
Would you still like to arrange a call?
