The following applies ONLY for the French market: "Bleu Ciel tarif"
In France there is a preferential kWh rate called "Bleu Ciel tarif". This rate divides
the days of the year in:
▪
blue days (preferential electricity rate, ideal for heat pump operation),
▪
white days (ideal for heat pump and hybrid operation),
▪
and red days (high electricity rate, boiler operation preferred).
It is recommended to use the preferential kWh rate power supply contact (4) to
force boiler operation during red days. Note that sometimes it is required to set
the meter on such that, it only closes the contact on red days. Please refer to the
manual of the applicable meter.
The indoor unit and gas boiler are NOT compatible with other combinations of
contacts (e.g., closed contacts on white/blue days). Connect the indoor unit and
gas boiler as follows: see illustration in column "Power supply is NOT interrupted"
in the table above.

During preferential kWh
rate power supply
activation, power supply
is NOT interrupted. The
outdoor unit is turned off
by the control. The gas
boiler can still operate.
Remark: The electricity
company must always
allow the power
consumption of the
indoor unit.

During preferential kWh
rate power supply
activation, power supply
is interrupted
immediately or after
some time by the
electricity company. In
this case, the indoor unit
must be powered by a
separate normal power
supply. The outdoor unit
CANNOT operate, but the
gas boiler can operate.
