2 Receiver controlling the signal of the electricity company
3 Power supply to outdoor unit (refer to the installation
manual delivered with the outdoor unit)
4 Voltage free contact to indoor unit
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

Connect the indoor unit to a normal kWh rate power supply
If the benefit kWh rate power supply is of type 2 or 3 (power
interruption of main power supply to outdoor unit), the indoor unit
should be connected to a normal kWh rate power supply to allow
continuous indoor control and operation (e.g., pump).
Disconnect terminal X6YA from X6Y and connect X6YB to X6Y.

■
In case the benefit kWh rate power supply function is
enabled, the screed dry-out function can not be
enabled.
■
When connecting the equipment to a benefit kWh rate
power supply, change field setting [d-01]. When
benefit kWh rate power supply is of type 1 or indoor
unit is connected to a normal kWh rate power supply
4
(via 30-31, X2M) change both field settings [d-01] and
[d-00]. Refer to
Local shift value weather dependent" on page
■
If the benefit kWh rate power supply is of type 1 or
indoor unit is connected to a normal kWh rate power
supply, the unit will be forced to off. Controlling the
solar pump is still possible.
When the benefit kWh rate signal is sent, the
centralised control indicator e will flash to indicate
that the benefit kWh rate is active.
■
If the benefit kWh rate power supply is of type 2 or 3
and indoor unit is not connected to a normal kWh rate
power supply, then the heaters cannot be controlled.
This power supply interruption should not be longer
than 2 hours, otherwise the real time clock of the
controller will be reset.
During power supply interruption, the controller
display will be blank.
