how do i decrease the pressure on my sime combi boiler?

i left the braided hose on and the knob was not shut tight (sime super 102 de luxe). overnight the pressure increased from 1 bar to 3 bar. ive tightened the knob and disconnected the hose, but now how do i lower the pressure? do i drain water from one of the radiators?

I have friendly model. I take front panel off and locate the drain plug, mine just next to pump, and drain into a jug or similar. It is quick and easier than drawing water from a radiator. A very small ammount will get it down from 3 to 1.

just bleed a rad that will get the pressure down.
