Temperature sensors
The temperature sensors for the outdoor and water heater are connected to the terminal blocks,
which are shown in the layout diagram of the control elements (see, Section: “Heat pump electrical
connection diagram”). A two-core 0.5 ÷ 1mm
2
cable must be routed from the heat pump to the
outdoor temperature installation location.
It is recommended that the outdoor sensor be installed on the north side or in a place that is not
exposed to direct sunlight.
In models without integrated water heater, a two-
core 0.5 ÷ 1.0 mm
2
cable must be routed from
the heat pump to the hot water tank.

Phase sequence relay
The heat pump features a built-in phase sequence relay that ensures that the compressor is
running in the correct phase sequence. The relay is equipped with PWR and OUT indicator lights.
When the heat pump is switched on and the phases are in the correct sequence, the PWR display
lights up yellow and OUT lights up green. If it is not connected properly, the PWR indicator lights up
in yellow and the OUT indicator does not light up. In this case, reset the correct phase sequence so
that the OUT indicator lights up in green.
