Possible types of benefit kWh rate power supply
Possible connections and requirements to connect the equipment to
such power supply are illustrated in the figures below:
For V1 unit types only (1~)
For Y1 unit types only (3~)
When the indoor and outdoor unit are 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 7 and 8 of X3M (as illustrated in the figure
above).
When parameter [6-04]=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
(1)
.
When parameter [6-04]=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

In case of benefit kWh rate power supply installation,
remove the wiring bridges on X2M before installing the
normal kWh rate power supply.
(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 field setting "[8] Option setup, [8-01]" in the chapter "Field
settings" on page 19.
