ON / OFF button
This button must be pressed once to turn on the controller. The
light in the button will glow when the controller is on. A
controller cannot be turned on if water is flowing from a hot tap.
To turn off a controller, press the on / off button once. The light
will go out. A controller can be turned off whilst water is flowing.
Priority light
This light will glow on a controller when that controller has
priority. The Bathroom controller(s), if they are turned on, have
priority over the Kitchen controller. Priority means that controller
has control of the water heater temperature setting. The water
temperature setting can only be adjusted by the controller that
has priority.
In use light
This light will glow on all controllers, whether they are on or off,
when hot water is flowing, regardless of which controller has
priority.
Display panel
The current temperature setting is displayed on all controllers
(whether hot water is flowing or not), when any controller is on.
If all controllers are off, then the display remains blank. The
water volume can also be displayed on the Kitchen controller.
The x10l symbol glows when the water volume is displayed.
i (up button) The up button increases the temperature setting.
j (down button) The down button decreases the temperature setting.
water volume button
(Kitchen controller only) – This feature enables an alarm to
sound when a set volume of water has flowed through the water
heater (refer to notes below).
Water volume notes:
• The water volume function is designed to warn, by a beeping sound, that a certain
volume of water has been delivered from the water heater. It does not stop either the
flow of or the heating of water.
• The Kitchen controller does not require priority nor to be on in order to set the water
volume function.
• The water volume function can be set whilst a hot tap is open.
• The water volume alarm will only sound from the kitchen controller.
• The factory preset water volume is 180 litres.
• To turn off the water volume function before the alarm sounds, press the water volume
button twice.
• The water volume is measured as the water flows through the water heater. Therefore if
more than one hot tap is open, the alarm will respond to the total water volume drawn
from all taps and the expected water volume from the first tap will be decreased.
• If the hot tap is closed before the set water volume flows through the water heater and
the water volume button is left on, then the alarm will sound when the remaining water
volume is consumed during a later operation. To prevent the alarm from sounding,
press the water volume button twice to turn it off.
