Main advantages offered by this function:
- a guarantee that the heat pump operates long enough to attain the required temperature, in
particular during initial warm-up periods (no longer necessary to manually switch on the filter system
24h/24).
- constant control and monitoring of the pool heating requirements, even when the filter system has
been switched off by the timer.
Connection of the “priority heating” function:
to use terminals 16 and 17 to come to control the pump of
filtration using the dry contact (I max. = 5 has
under 230Vac with circuit of class AC1 and I max. = 1,2A
under 230Vac with circuit of class AC3), see diagram hereafter.
“Priority heating” wiring and operating diagram:
A1-A2: supply to power contactor coil
of the filtering pump
filter timer
power contactor (3-pole or 2-pole), supplying the filter pump
connection cable, wire gauge 2 x 1.5 mm² minimum (service voltage 300Vac)
controller board with “priority heating” output, terminals 16-17
heat pump B1 regulation electronic card (see placing § “dimensions and description” in the appendix)
Never power the filter pump motor directly through terminals 16-17 located on plate
.
Terminals 16-17 may remain live even if the heat pump is disconnected from the power
source.
Before performing any work on the machine, cut off the power to the filter timer at its
circuit breaker (F on the diagram above).
Incorrect connection of terminals 16-17 may damage the regulator and renders the
warranty invalid.
The minimum wire gauge for connection of the priority heating function is: 2x1.5 mm²,
of type RO2V or equivalent in countries outside the European Community, and with an
outer diameter between 8 and 13 mm.
Remove the plug (upper the cable gland) and fit the cable gland for passage of the
cable into the unit.
Once the cable is inserted in this stuffing box, block it by pulling lightly on the cable to
retract it one centimeter.
The cable used for priority heating and the electrical power supply cable must be strapped
together inside the unit until just after the stuffing box.
