1.4 I Option connections
Connecting the "Heating priority" option:
• 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.
• Any incorrect connection to terminals P1 to P2 may damage the appliance and cancel its
warranty.
• Terminals P1 to P2 are exclusively dedicated to the options and must never be used to directly
supply other equipment.
• When intervening on terminals P1 to P2, there is a risk of electrical return current, injuries,
material damage and death.
• Use cables with a section of at least 2x0.75mm² , RO2V type and with a diameter between
8 and 13mm.
• If the power of the filtration pump exceeds 5A (1000W), activating heating priority requires the
use of a power relay.
• 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.
1.4.1 "Heating priority" option
Connect the filtration pump to the heat pump (= activate the heating priority) to force the filtration to operate if the
water is not at the desired temperature.
When heating priority is activated:
• If heating is needed, the heat pump will force the filtration pump to run even though it is outside its filtration hours
to maintain the pool water temperature.
• If heating is not needed :
- And filtration is inside its running hours : the filtration pump will continue to run without the heat pump.
- And filtration is outside its running hours : the filtration pump will not run.
• Make sure that the electricity supply has been switched off.
• Connect a 230 V/dry contact relay (not included) to terminals P1 and P2 (230 V output), then connect the connection
cable (not included) from the output of this relay to the filtration timer as shown in the diagram below.
• By default, when connecting the filtration pump to the heat pump electrically, the heating priority is activated
(system parameter L0, set on "1" by default): every 120 minutes (system parameter L1, set on "120" by default), the
filtration pump will run during 5 minutes to check if heating is needed.
• Access to the system parameters and modify L0 and L1, if needed, see § "4.4 I Accessing to system parameters".
Example : if choosing L1=90, the filtration pump will be activated every 90 minutes to check if heating is needed.
