1.5 I Option connections
Connecting the "Heating priority" and "remote control" options :
• Before any work inside the appliance, you must cut the appliance’s electricity supply as there is
a risk of electric shock which may cause material damage, serious injury or even death.
• There is a risk of electrical return current, injuries, material damage and death when working
on terminals 1 to 2.
• Any connection error with terminals 1 to 2 may damage the appliance and invalidate its
warranty.
• Terminals 1 to 2 are dedicated to the options and must never be used to directly supply other
equipment.
• Use cables with a section of at least 2x0.75 mm² , RO2V type and with a diameter between 8
and 13 mm.
Before connecting any options: remove the seal (above the cable gland) and install the cable gland provided in order to
pass the cables into the appliance.
The cables used for the options and the power cord must be kept separate (risk of interference) using a collar inside the
appliance just after the glands.
1.5.1 "Heating priority" option
• This function allows the appliance to start or maintain filtration (according to setting "P3") in order to detect the
water temperature and thus activate the filt heating unit to maintain a constant water temperature. The
filter pump is thus said to be slaved to the heating system.
Filtration is kept in operation or activated if the pool temperature falls below the desired temperature.
• For the connection, connect the filtration timer to terminals 1 and 2 (dry contact, no polarity).

1.5.2 "Remote control" option
• This option enables the appliance's user interface to be transferred in order to control the appliance remotely. To do
so, use the remote control kit .
• To connect the kit, connect the signal wire to the pins on the controller.
• Pass the wire through the connection block.
• Then connect the connector to the printed circuit board.
