„In use‟ light
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.
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.
This light will glow on all controllers, whether they are on or off,
when hot water is flowing, regardless of which controller has
priority.
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.
