6.4.2 About preferential kWh rate power supply
Electricity companies throughout the world work hard to provide
reliable electric service at competitive prices and are often
authorized to bill clients at benefit rates. E.g. time-of-use rates,
seasonal rates, Wärmepumpentarif in Germany and Austria, ...
This equipment allows for connection to such preferential kWh rate
power supply delivery systems.
Consult with the electricity company acting as provider at the site
where this equipment is to be installed to know whether it is
appropriate to connect the equipment in one of the preferential kWh
rate power supply delivery systems available.
When the equipment is connected to such preferential kWh rate
power supply, the electricity company is allowed to:
▪ interrupt power supply to the equipment for certain periods of time;
▪ demand that the equipment only consumes a limited amount of
electricity during certain periods of time.
The indoor unit is designed to receive an input signal by which the
unit switches into forced off mode. At that moment, the gas boiler
can still operate to provide heating, but the outdoor unit compressor
will NOT operate.
Whether the power supply is interrupted or not, the wiring to the unit
is different.

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.

Following applies ONLY for French market: "blue ciel tarif"
In France there is a preferential kWh rate "blue 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 table above.
