INFORMATION
Electricity price can only be set when bivalent is ON
([A.2.2.6.1] or [C-02]). These values can only be set in
menu structure [7.4.5.1], [7.4.5.2] and [7.4.5.3]. Do NOT
use overview settings.
INFORMATION
Boiler efficiency [A.6.A] or [7‑05] becomes visible when
bivalent is ON ([A.2.2.6.1] or [C‑02]).
CAUTION
Make sure to observe all rules mentioned in application
guideline 5 when bivalent operation function is enabled.
Daikin shall NOT be held liable for any damage resulting
from failure to observe this rule.
INFORMATION
The permission signal for the auxiliary boiler is located on
X8M/3+4 of option box EK2CB07CAV3. When it is
activated, contact X8M/3+4 is closed. When it is
deactivated, X8M/3+4 is open. See the illustration below
for the schematic location of this contact.

System settings

Auto-restart
When power returns after a power supply failure, the auto restart
function reapplies the user interface settings at the time of the power
failure. Therefore, it is recommended to always enable this function.
If the power supply might get interrupted (e.g. preferential kWh rate
power supply), always enable the auto restart function. Continuous
control of the hydro part of the outdoor unit can be guaranteed
independent of the preferential kWh rate power supply status, by
connecting the hydro part of the outdoor unit to a normal kWh rate
power supply.

# Code
[A.2.1.6] [D‑01] Connection to a preferential kWh rate
power supply:
▪ 0 (default): The refrigerant part of the
outdoor unit is connected to a normal
power supply.
▪ 1: The refrigerant part of the outdoor
unit is connected to a preferential kWh
rate
preferential kWh rate signal is sent by
the electricity company, the contact
will open and the unit will go in forced
off mode. When the signal is released
again, the voltage-free contact will
close
operation. Therefore, always enable
the auto restart function.
▪ 2: The refrigerant part of the outdoor
unit is connected to a preferential kWh
rate
preferential kWh rate signal is sent by
the electricity company, the contact
will close and the unit will go in forced
off mode. When the signal is released
again, the voltage-free contact will
open
operation. Therefore, always enable
the auto restart function.
[A.6.2.1] [D‑00] Which heaters are allowed to operate
during preferential kWh rate power
supply?
▪ 0 (default): None
▪ 2: Backup heater only
See table below.
Setting 2 is only meaningful if the
preferential kWh rate power supply is of
type 1 or the hydro part of the outdoor
unit is connected to a normal kWh rate
power supply (via X3M/5+6) and the
backup heater is NOT connected to the
preferential kWh rate power supply.
