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.
When connecting the equipment to a benefit kWh rate
power supply, change field setting [D-01]. In case the
benefit kWh rate power supply is of the type that power
supply is not interrupted (like illustrated above as type 1)
change both field settings [D-01] and [D-00]. Refer to
"[D] Benefit kWh rate power supply/Local shift value
weather dependent" on page 30 of chapter "Field settings".
If the benefit kWh rate power supply is of the type that
power supply is not interrupted, the unit will be forced to
off.
When the benefit kWh rate signal is sent, the centralised
control indicator e will flash to indicate that the benefit
kWh rate is active.
Relocation of the digital controller
The digital controller is from factory located on the indoor unit. (See
"Main components" on page 10 for actual position). If required, the
digital controller can be repositioned.
Be aware that only 1 digital controller can be connected to the indoor
unit.

Connect the terminals on top of the front part of the digital
controller and the terminals inside the unit (P1 to 16, P2 to 16a).
■
NOTE When wiring, run the wiring away from the
power supply wiring in order to avoid
