For the room thermostats, its is important that they are battery-powered, i.e. that they do not
have any supply of 220V. NC (normally closed contact) is used for connection on the thermostat itself.
The boiler may operate even if the central heating pump has not been connected, but the
manufacturer recommends that it be installed because it has a function of a safety element. It turns on
when the temperature of water in the boiler exceeds
90˚C
