EHBH/X16
Daikin Altherma - Low Temperature Split
4P313776-1 – 2012.05
8 Configuration
For systems with an integrated domestic hot water tank (only for
EHVH/X
)
Auto-restart
When power returns after a power supply failure, the auto restart
function reapplies the remote controller settings at the time of the
power failure. Therefore, Daikin recommends to always enable the
function.
If the preferential kWh rate power supply is of the type that power
supply is interrupted, always enable the auto restart function.
Continuous indoor unit control can be guaranteed independent of the
preferential kWh rate power supply status, by connecting the indoor
unit to a normal kWh rate power supply.
Preferential kWh rate power supply
Only for EHBH + EKHW*:
Only for EHVH: Do NOT use 1 or 3.
Power saving function
Defines whether the outdoor unit power supply can be interrupted
(internally by indoor unit control) during stand-still conditions (no
space heating/cooling nor domestic hot water demand). The final
decision to allow power interruption of the outdoor unit during
standstill depends on the ambient temperature, compressor
conditions and minimum internal timers.
To enable the power saving function setting, [E-08] needs to be
enable at the user interface in combination with the removal of the
power saving connector at the outdoor unit. The power saving
connector at the outdoor unit shall only be removed when the main
power supply to the application is switched OFF.

Code
Description
N/A
[5-02]
Space heating priority.
Defines whether backup heater will
assist the heat pump during domestic
hot water operation.
Consequence: Shorter tank heating
operation time and shorter interruption
of the space heating cycle.
This setting MUST always be 1.
[5-01] Equilibrium temperature and [5-
03] Space heating priority temperature
are related to backup heater. So, you
must set [5-01] and [5-03] to the same
value.
If the backup heater operation is limited
([4-00]=0) and the outdoor temperature
is lower than setting [5-03], the
domestic hot water will not be heated
with the backup heater.
N/A
[5-03]
Space heating priority temperature.
Defines the outdoor temperature which
below the backup heater will assist
during domestic hot water heating.

If a solar kit is installed, what has
priority to heat up the tank?
Q
0: Solar kit
Q
1: Heat pump
[A.6.1.1.1]
[C-01]
If there is a simultaneous demand for
space heating/cooling and domestic hot
water heating (by heat pump), which
operation mode has priority?
Q
0: The operation mode with the
highest request has priority.
Q
1: Always space heating/cooling
has priority.

Which heaters are allowed to operate
during preferential kWh rate power
supply?
Q
0 (default): None
Q
1: Booster heater only
Q
2: Backup heater only
Q
3: All heaters
Only for EHBH + EKHW*: See table
below.
Only for EHVH: See table below.
Settings 1, 2 and 3 are only meaningful if
the preferential 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
preferential kWh rate power supply.
