In some systems the boiler runs without the thermostat. It has its own
internal thermostat that controls the temperature of the water in the boiler
always keeping it hot when the boiler is turned on. The wall thermostat will
turn on a pump sending hot water to the radiators when needed and turning
the pump off when not needed. But the boiler always keeps itself hot. Other
systems work differently.

Yes, that would be a maintained temperature boiler as opposed to a cold
start boiler, usually found on boilers that have a coil for domestic hot
water. An aquastat in the water jacket controls the temperature, connected
to a triple aquastat relay. Of course these days with hi end digital
controls, that stuff will soon be a thing of the past
