Abstract

The method of controlling operation of a plurality of fixtures comprises the steps of establishing a maximum liquid flow rate and determining which of the fixtures required operation. A determination is then made of the liquid flow rate of the fixture requiring operation and a calculation is made of whether operation of the fixture requiring operation will cause the maximum flow rate to be exceeded. The fixture requiring operation is caused to operate if the maximum flow rate will not be exceeded and is prevented from operating if the maximum flow rate will be exceeded.
