Controllers (cont’d)
Note: If one or more controllers are installed, at least one must be ON for the water heater
to operate. If all controllers are OFF the water heater will only deliver cold water.
Selectable Temperatures:
Kitchen Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 50*, 55*, 60*, 70*, 75*°C.

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 x10
l
symbol
glows when the water volume is displayed.
(up button)
The up button increases the temperature setting.
(down button)
The down button decreases the temperature setting.
water volume button
(Kitchen controller only)

alarm to sound when a set volume of water has
