I Option Connections - Zodiac PM40 Series Instructions For Installation And Use Manual

1.5 I Option connections

Connecting "Heating Priority" 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 filtration (continuously or in 5-minute cycles every 120
minutes) in order to detect the water temperature and thus activate the filtration + 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, maximum intensity
1.5A, above this intensity, connect an appropriate contactor (not supplied)).
