MANUAL ACTIVATION SWITCH
•
To obtain the full benefits of the water heater and Readyhot system, water controllers should be used. However
it is possible to use a manual activation switch to activate the Readyhot system if water controllers are not fitted.
Parts required:
•
Two core sheathed (double insulated) flex with minimum cross sectional area of 0.5 mm
•
Switch Harness (U268-605) this comes supplied with the Readyhot system.
•
One or more manual activation switch(es). Suggested part is Clipsal 30PBL or equivalent.
Procedure:
•
Install the manual activation switch(es) in the desired location in accordance with manufacturer instructions.
Run the cable between the manual activation switches and the Readyhot system.
If more than one manual activation switch is used then the cables will need to be connected in
parallel before entering the Readyhot system. Only one cable can be connected to the terminals
NOTE
of the Readyhot system.
•
Run the cable into the Readyhot enclosure using the same entry point as the communication cable fitted
between the Readyhot and the Dux Endurance Water heater.
•
The switch harness is connection between the cable from the manual activation switch(es) and the Printed
Circuit Board (PCB) of the Readyhot. Connect the two wires from the manual activation switch cable to the Blue
and Black wires on the switch harness (polarity does not apply). If an LED indicator is used, connect the two
wires from the LED indicator to the Red and Black wires on the switch harness. Note: that the Orange wire on
the switch harness is not used.
•
Plug the switch harness into the PCB as shown in the Circuit Diagram on page 8.

WATER CONTROLLERS

•
At least one controller must be fitted to enable activation of the Readyhot system. Up to three or four controllers
can be fitted depending on water heater model. Refer to the 'WATER CONTROLLERS' section of the
'Installation Instructions' supplied with the Dux Endurance water heater and the Instruction sheet supplied with
the Dux water controller.
•
Other types of Dux water controllers can be fitted but will not enable activation of the Readyhot system.
HEATED WATER DELIVERY TEMPERATURE
The maximum water temperature delivered at the hot water outlets is determined by the pre-set limit programmed
into the water heater. Local regulations and/or the requirements of AS/NZS 3500 must be considered regarding
the temperature limitations of hot water supplied to areas used primarily for personal hygiene. The temperature of
water to these areas may be limited to 50°C or less. If you are unsure about local regulations, contact your
regulating authority or Dux Manufacturing.
