[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:
■
[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
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
(1)
.
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
(2)
.
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
dependent set point" on page 24
) 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.
CAUTION
Make sure to observe all rules mentioned in
"8.5. Application 5" on page 9
function is enabled.
Daikin shall not be held liable for any damage
resulting from failure to observe this rule.
INFORMATION
■
The combination of setting [4-03]=0/2 with
bivalent operation at low outdoor temperature can
result in domestic hot water shortage.
■
The bivalent operation function has no impact on
the domestic water heating mode. The domestic
hot water is still and only heated by the indoor unit.
■
The permission signal for the auxiliary boiler is
located on the EKRP1HB (digital I/O PCB). When
it is activated, the contact X1, X2 is closed and
open when it is disactivated. See figure for the
schematic location of this contact.

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.
(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
