Preheat Function
When the “Preheat” function is activated and used in accordance with these instructions, water in the pipework
connected between the water heater and the hot water outlets in your house is warmed before any outlets are
opened. This results in water savings and added convenience.
Preheat Operation
1. Ensure that the hot water unit is on (temperature digits are displayed in the digital monitor
3
). If more than
one water controller is tted press the ‘Priority Transfer’ button
8
to pass on priority to your desired water
controller. The ‘Controller Priority’ indicator
5
will illuminate to conrm that priority has been assigned to this
water controller and that the hot water unit is ready to deliver hot water.
1. Select the desired temperature using the 'Temperature Control' buttons
6
until the required temperature is
displayed in the digital monitor
3
.
2. Press the ‘Preheat’ button
1
once. The ‘Preheat’ indicator
2
and the ‘In Use’ indicator
7
will illuminate,
signifying that the preheat system has been activated.
3. Wait approximately two minutes before opening an outlet. This will allow the water in the pipework to be
warmed.
NOTE
The waiting time may be longer or shorter than two minutes depending on your particular
installation conguration.
The preheat function is completed 5 minutes after activation and the ‘Preheat’ indicator will go
out� This is to conserve energy� To reactivate, simply repeat steps 2-4 above�
* If the ‘Preheat’ button is pressed and the ‘Smartstart’ preheat unit is not installed, the ‘Preheat’
indicator will still light but there will be no preheat function� The ‘Preheat’ indicator will go out
after a short time and will not a󰀨ect the other functions of the water controller or water heater.
After using the Shower Saver / Bath Fill function wait 30 seconds before activating the “Preheat”
function� Attempting to use the “Preheat” function earlier will result in voice prompts being
repeated until the system is reset. The system can be reset by pressing the ‘On /O󰀨' button twice.
Water Controller Functions
Water controller functions such as temperature control and transfer of priority between multiple controllers are not
a󰀨ected by the operation of the preheat. Such functions are described in the applicable sections of this manual.
