Abstract
A fluid control device includes an electric motor mechanically connected to a fluid valve and a sensor coupled to a fluid pipe section. The sensor may be a temperature, pressure or flow rate sensor. A control device processor is configured to enter into a pre-occupancy mode when powered and never previously wirelessly connected to a remotely disposed fluid monitoring and control system. The pre-occupancy mode may close the fluid valve if at least one of the following occurs: exceeding a first preset threshold for a pressure decay test; exceeding a second preset threshold for a maximum flow rate; exceeding a third preset threshold for a maximum flow duration; exceeding a fourth preset threshold for a maximum flow volume; exceeding below a fifth preset threshold for a low temperature; exceeding above a sixth preset threshold for a high temperature; and/or exceeding above a seventh preset threshold for a high pressure.
