WATER CONTROLLER INSTALLATION
CONNECTING COMMUNICATION CABLES TO THE WATER HEATER
Communication cables connect the water heater to water controllers and operate at an extra low
voltage (12 Volts DC) which is supplied from the water heater. Communication cables are supplied
with the water controllers (15m) and are fitted with spade terminals for connection to water heater. Up
to two cables can be connected directly to the water heater. Extension cables are available from Dux.
Alternatively, two core sheathed (double insulated) flex with minimum cross sectional area of 0.5mm²
may be used. Cable lengths must not exceed 20 metres.
To connect up to two cables to the Water Heater
DO NOT attempt to connect cables to the water heater unless the electric power to
the water heater is switched ‘off’ otherwise damage to electrical components may
occur.
1. Isolate the electric power supply by switching the power point off and removing the power plug of
the water heater from the electric power socket.
2. Remove the retaining screw at the base of the appliance.
3. Swing the door open and thread the cable through the weather seal of the cable access hole
in the direction shown allowing sufficient cable length so that the sheath of the cable can be
secured with cable clamp supplied with the transceiver.
4. Loosen screw terminals and and connect the cable spade connectors to these terminals
and re-tighten. Polarity is not important, either wire colour can be connected to either terminal.
5. Return to the original position taking care not to damage cable wires in the process and replace
the retaining screw .
