The following layout drawings are provided purely as a guideline to the various water systems possible, and in no way
intended as complete.
b
Never replace the controller if there is no need.
b
Certain specific applications may require the inclusion of additional system components for operational and/or
safety purposes, such as, for example, shut-off valves, non-return valves, temperature control devices, anti-scald
devices, etc., and these must therefore be provided.
The layouts that can be adopted in the case of the SC SUN 300 are number 17 and number 18, illustrated in the figures
below.

SETUP WIZARD
The first time the controller is switched on, once the lan-
guage and the clock are set, a prompt will appear asking
whether or not the setup wizard is required. The wizard
can be called up again at a later time if needed, from the
special functions menu. The wizard will guide the user
through the basic settings in the correct sequence, pro-
viding a brief description of each parameter displayed.
Pressing “esc” once, the screen returns to the previous
value, so that it is always possible to go back or make
changes. Pressing “esc“ repeatedly, the steps of the se-
lection procedure can be undone one by one, without
confirming the wizard input. Finally, accessing menu 3.2
and selecting “Manual” mode, the installer can test the
various outputs with the components connected, and ver-
ify whether or not the readings from the sensors are relia-
ble. Thereafter, automatic mode is activated.
Start now the setup wizard?
