摘要： A hydraulic unit is for use in a multi zone heating system. The hydraulic unit comprises a variable output pump; a plurality of independently controllable valves, each valve being associated with one heating zone; and at least one temperature sensor. Each heating zone receives a heated water supply from a common heat source via the pump. The heating system includes a controller comprising a processor which receives signals from the at least one temperature sensor which processes the signals in accordance with control software. Command signals are sent to the pump and the plurality of independently controllable valves, to vary the flow rate of water from the common heat source to each of the heating zones independently one to another. Remote fault diagnosis and control is also provided.
