Daikin Altherma – Low temperature split
4P499573-1A – 2018.11
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
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.
Anti-legionella heater
Capacity
The capacity of the anti-legionella heater must be set for the energy
metering and/or power consumption control feature to work properly.
When measuring the resistance value of the anti-legionella heater,
you can set the exact heater capacity and this will lead to more
accurate energy data.
#
Code
Description
[9.4.1]
[6‑02]
Capacity [kW]. Only applies to domestic
hot water tank with an internal anti-
legionella heater. The capacity of the
anti-legionella heater at nominal voltage.
Range: 0~10 kW
BSH allowance schedule
Program when the anti-legionella heater can operate. You can set a
schedule for the anti-legionella heater here using the schedule
screen. Two actions per day are allowed in a week schedule. For
more information, see
"8.3.8 Schedule screen: Example" on
.
Example:
Only allow the anti-legionella heater to operate during the
night.
BSH eco timer
#
Code
Description
[9.4.3]
[8-03]
Anti-legionella heater delay timer.
Start-up delay time for the anti-legionella
heater when domestic hot water mode is
active.
▪ When domestic hot water mode is
NOT active, the delay time is
20 minutes.
▪ The delay time starts from anti-
legionella heater ON temperature.
▪ By adapting the anti-legionella heater
delay time versus the maximum
running time, you can find an optimal
balance between the energy efficiency
and the heat up time.
▪ If the anti-legionella heater delay time
is set too high, it might take a long
time before the domestic hot water
reaches its set temperature.
▪ The setting [8‑03] is only meaningful if
setting [4‑03]=1. Setting [4‑03]=0/2/3/4
limits
the
anti-legionella
heater
automatically in relation to heat pump
operation time in domestic water
heating mode.
▪ Make sure that [8‑03] is always in
relation with the maximum running
time [8‑01].
Range: 20~95 minutes
Operation
#
Code
Description
[9.4.4]
[4-03]
Defines the operation permission of the
anti-legionella heater depending on
ambient, domestic hot water temperature
or operation mode of heat pump. This
setting is only applicable in reheat mode
for applications with separate domestic
hot water tank. When setting
[4‑03]=1/2/3/4, the anti-legionella heater
operation can still be restricted by the
anti-legionella heater allowance
schedule.
