CAUTION
In case of benefit kWh rate power supply installation,
remove the wiring bridges on X2M before installing the
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
The benefit kWh rate power supply is of the type that power supply is
not interrupted.
type 2 and 3
The benefit kWh rate power supply is of the type that power supply
will be interrupted after elapse of time or 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 "[3] Auto restart" on page 32.
(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 "[3] Auto restart" on page 32.

CAUTION
Benefit kWh rate power supplies that completely shut
power supply like illustrated above as types 2 and 3
are not allowed for this application because of the
water freeze prevention that would not be powered.
When connecting the equipment to a benefit kWh rate
power supply, change field settings [D-01] and both
[D-01] and [D-00] in case the benefit kWh rate power
supply is of the type that power supply is not
interrupted (like illustrated above as type 1). Refer to
"[D] Benefit kWh rate power supply/Local shift value
4 weather dependent" on page 38 of chapter "Field
settings".
NOTICE
If the benefit kWh rate power supply is of the type that
power supply is not interrupted, the unit will be forced to
off. Controlling the solar pump is still possible.
