[d] Benefit kWh rate power supply/Local shift value weather
dependent
Benefit kWh rate power supply
■ [d-00] Switching off heaters: Defines which heaters are
switched off when the benefit kWh rate signal of the
electricity company is received.
If [d-01]=1 or 2 and the benefit kWh rate signal of the
electricity company is received, following devices will be
switched off.
Only for RKHW*

Only for RKHTS

■ [d-01] Unit connection to benefit kWh rate power supply:
Defines whether or not the outdoor unit is connected to a
benefit kWh rate power supply.
If [d-01]=0, the unit is connected to a normal power supply
(default value).
If [d-01]=1 or 2, the unit is connected to a benefit kWh rate
power supply. In this case the wiring requires specific
installation like explained in "Connection to a benefit kWh
rate power supply" on page 21.
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
(3)
.
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

.
Local shift value weather dependent
The local shift value weather dependent field setting is only relevant
in case weather dependent set point (see field setting "[1] Weather
dependent set point" on page 27) is selected.
■ [d-03] Local shift value weather dependent: determines the
shift value of the weather dependent set point around
outdoor temperature of 0°C.

■ [E-00] Readout of the software version (example: 23)
■ [E-01] Readout of the EEPROM version (example: 23)
■ [E-02] Readout of the unit model identification (example: 11)
■ [E-03] Readout of the liquid refrigerant temperature
■ [E-04] Readout of the inlet water temperature

INFORMATION
■ [d-00] settings 1, 2 and 3 are only meaningful
if the benefit kWh rate power supply is of type
1 or indoor unit is connected to a normal kWh
rate power supply (via 30-31 X2M) and the
backup heater and booster heater are not
connected to the benefit kWh rate power
supply.
■ For RKHTS, do not select 1 or 3 value.
(3) 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 28.
(4) 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 28.
