LIMITATIONS ON ELECTRICAL SUPPLY
If on installation of the Flow boiler, the site survey indicates that the total demand for power exceeds the incoming supply if all devices are switched
on at the same time, the priority must be given to one device.
Typically but not always this other unit is the electric shower, to give priority to the shower a simple relay is added as shown in diagram below. When
the shower is used the boiler will cease to operate. When the shower is turned off the boiler operation will recommence.
To connect the relay, the control side of the relay is attached to the switched supply of the shower and the normally closed contact side of the relay is
attached to the demand signal of the boiler.
