Hi.
On my boiler there is a box with a dial. This has a green light around it. It has numbers on it.
What is this for? Is it a pressure release valve that can be adjusted? When I turn it to zero, it flashes and water flows somewhere? Lol.
It was set at 2. It also turns clockwise to certain numbers too.
Thanks.
