room stat

A mechanical room, boiler room or plant room is a room or space in a building dedicated to the mechanical equipment and its associated electrical equipment, as opposed to rooms intended for human occupancy or storage. Unless a building is served by a centralized heating plant, the size of the mechanical room is usually proportional to the size of the building. A small building or home may have at most a utility room but in large buildings, mechanical rooms can be of considerable size, often requiring multiple rooms throughout the building, or even occupying one or more complete floors (see: mechanical floor).

    Bypassing faulty room stat

    If removing the two wires from the room stat that connect to the boiler to place a link in the room stat terminals in the boiler. As I think a faulty room stat is stopping the boiler from firing. Is it acceptable to leave the link in till I can pop back with a new stat? Bad practice I guess
