Voltage
▪ For a 6V model, this can be set to:
▪ 230V, 1ph
▪ 230V, 3ph
▪ For a 9W model, this is fixed to 400V, 3ph.
# Code Description
[9.3.2] [5‑0D] ▪ 0: 230V, 1ph
▪ 1: 230V, 3ph
▪ 2: 400V, 3ph
Configuration
The backup heater can be configured in different ways. It can be
chosen to have a 1-step only backup heater or a backup heater with
2 steps. If 2 steps, the capacity of the second step depends on this
setting. It can also be chosen to have a higher capacity of the
second step in emergency.
# Code Description
[9.3.3] [4‑0A] ▪ 1: Relay 1 / Relay 1+2
▪ 2: Relay 1 / Relay 2
▪ 3: Relay 1 / Relay 2 Emergency Relay
1+2
INFORMATION
Settings [9.3.3] and [9.3.5] are linked. Changing one
setting influences the other. If you change one, check if the
other is still as expected.
INFORMATION
During normal operation, the capacity of the second step of
the backup heater at nominal voltage is equal to
[6‑03]+[6‑04].
INFORMATION
If [4‑0A]=3 and emergency mode is active, the power
usage of the backup heater is maximal and equal to
2×[6‑03]+[6‑04].
INFORMATION
Only for systems with integrated domestic hot water tank: If
the storage temperature set point is higher than 50°C,
Daikin recommends NOT to disable the backup heater
second step because it will have a big impact on the
required time for the unit to heat up the domestic hot water
tank.
Capacity step 1
# Code Description
[9.3.4] [6‑03] ▪ The capacity of the first step of the
backup heater at nominal voltage.
Additional capacity step 2
# Code Description
[9.3.5] [6‑04] ▪ The capacity difference between the
second and first step of the backup
heater at nominal voltage. Nominal
value depends on backup heater
configuration.
Equilibrium
# Code Description
[9.3.6] [5-00] Equilibrium: Is backup heater operation
allowed above equilibrium temperature
during space heating operation?
▪ 1: NOT allowed
▪ 0: Allowed
[9.3.7] [5-01] Equilibrium temperature: Outdoor
temperature below which operation of
the backup heater is allowed.
Range: –15°C~35°C
INFORMATION
Above 10°C ambient temperature, the heat pump will
operate until 55°C. Configuring a higher setpoint with an
ambient temperature that is higher than the set equilibrium
temperature will prevent the backup heater from assisting.
The backup heater will ONLY assist if you increase the
equilibrium temperature [5‑01] to the required ambient
temperature you need to reach the higher setpoint.
Operation
# Code Description
[9.3.8] [4‑00] Backup heater operation:
▪ 0: Restricted
▪ 1: Allowed
▪ 2: Only DHW Enabled for domestic hot
water, disable for space heating
INFORMATION
Only for systems with integrated domestic hot water tank: If
backup heater operation during space heating needs to be
limited but can be allowed for domestic hot water
operation, then set [4‑00] to 2.
Emergency
Emergency
When the heat pump fails to operate, the backup heater can serve
as an emergency heater and either automatically or non-
automatically take over the heat load.
▪ When auto emergency is set to Automatic and a heat pump failure
occurs, the backup heater will automatically take over the heat
load and the domestic hot water production.
▪ When auto emergency is set to Manual and a heat pump failure
occurs, the domestic hot water and space heating operation will
stop and need to be recovered manually via the user interface. To
recover operation manually, go to the Malfunctioning main menu
screen, where the user interface will then ask you to confirm
whether the backup heater can take over the heat load or not.
We recommend to set Emergency to Automatic if the house is
unattended for longer periods.
# Code Description
[9.5] N/A ▪ 0: Manual
▪ 1: Automatic
INFORMATION
The auto emergency setting can be set in the menu
structure of the user interface only.
