“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.
