Connection to a benefit 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 benefit 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 benefit kWh rate
power supply delivery systems available, if any.
When the equipment is connected to such benefit 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 outdoor unit
compressor will not operate.

5 Normal kWh rate power supply
When the outdoor unit is connected to a benefit kWh rate power
supply, the voltage free contact of the receiver controlling the benefit
kWh rate signal of the electricity company must be connected to
clamps 17 and 18 of X2M (as illustrated in the figure above).
When parameter [d-01]=1 at the moment that the benefit kWh rate
signal is sent by the electricity company, that contact will open and
the unit will go in forced off mode
When parameter [d-01]=2 at the moment that the benefit kWh rate
signal is sent by the electricity company, that contact will close and
the unit will go in forced off mode
Type 1
This type of benefit kWh rate power supply is not interrupted.
Type 2
This type of benefit kWh rate power supply is interrupted after elapse
of time.
Type 3
This type of benefit kWh rate power supply is interrupted immediately.
(1) When the signal is released again, the voltage free contact will close and
the unit will restart operation. It is therefore important to leave the auto
restart function enabled. Refer to
(2) When the signal is released again, the voltage free contact will open and
the unit will restart operation. It is therefore important to leave the auto
restart function enabled. Refer to
