1 Benefit kWh rate power supply box
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
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
The benefit kWh rate power supply is of the type that power supply
will be interrupted after elapse of time.
Type 3
The benefit kWh rate power supply is of the type that 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 "[3] Auto restart" on page 19.
(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 19.

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" on page 22 of chapter "Field settings".
NOTE 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.

TART UP AND CONFIGURATION
The indoor unit should be configured by the installer to match the
installation environment (outdoor climate, installed options, etc.) and
user expertise.
It is important that all information in this chapter is read
4
sequentially by the installer and that the system is
configured as applicable.

DIP switch settings overview

DIP switch SS2 is located on the switch box PCB (see "Switch box
main components" on page 7) and allows configuration of domestic
hot water tank installation, room thermostat connection and pump
operation.
Switch off the power supply before opening the switch box
service panel and making any changes to the DIP switch
settings.

Room thermostat installation configuration
When no room thermostat is connected to
the indoor unit, toggle switch SS2-3 should be
set to OFF.
When a room thermostat is connected to the
indoor unit, toggle switch SS2-3 should be set
to ON.
On the room thermostat, set the hysteresis appropriately to
prevent the pump from repeatedly turning on and off (i.e.
chattering), and thereby impacting the lifetime of the pump.
