Daikin Altherma hybrid monobloc – Heat pump module

#
Code
Description
N/A
[8-06]
Leaving water temperature maximum
modulation:
Range: 0°C~10°C
Requires modulation to be enabled.
This is the value by which the desired
leaving water temperature is increased
or lowered.
INFORMATION
When leaving water temperature modulation is enabled,
the weather‑dependent curve needs to be set to a higher
position than [8-06] plus the minimum leaving water
temperature setpoint required to reach a stable condition
on the comfort setpoint for the room. To increase
efficiency, modulation can lower the leaving water setpoint.
By setting the weather‑dependent curve to a higher
position, it cannot drop below the minimum setpoint. Refer
to the illustration below.

Leaving water temperature: Emitter type
#
Code
Description
[A.3.1.1.7]
[9‑0B]
Emitter type:
Reaction time of the system:
▪ 0: (Quick)
Example:
Small water volume and
fan coils.
▪ 1: (Slow)
Example:
Large water volume, floor
heating loops.
Depending on the system water volume
and the heat emitters type, the heat up
of a space can take longer. This setting
can compensate for a slow or a quick
heating system by adjusting the unit
capacity during the heat up cycle.
Quick heat up function
Only applicable in case of *HY32AA gas boiler.
#
Code
Description
N/A
[C‑0A]
Indoor quick heat up function:
▪ 0: OFF.
▪ 1: On.
Only applicable in case of room
thermostat control. The function will
start up the gas boiler when the actual
room temperature is 3°C lower than the
desired room temperature. The large
boiler capacity can quickly boost up the
room temperature to the desired
temperature. This can be useful after
long periods of absence or after a
breakdown of the system.
Leaving water temperature: Delta T source
#
Code
Description
[A.3.1.3.1]
[1‑0B]
Heating: required temperature
difference between entering and
leaving water.
In case a minimum temperature
difference is required for the good
operation of the heat emitters in heating
mode.
Range: 3°C~10°C
6.2.6
Domestic hot water control
Only applicable in case of *HY32AA gas boiler, and an
optional domestic hot water tank is installed.
This is always applicable for Switzerland.
#
Code
Description
[A.4.1]
[6-0D]
Domestic hot water Type:
▪ 0 (Reheat only): Only reheat operation
is allowed.
▪ 1 (Reheat + sched.): Same as 2, but
between the scheduled heatup cycles,
reheat operation is allowed.
▪ 2 (Scheduled only): The domestic hot
water tank can ONLY be heated
according to a schedule.
[A.4.5]
[6-0E]
The maximum temperature that users
can select for the domestic hot water.
You can use this setting to limit the
temperature at the hot water taps.
INFORMATION
There is a risk of space heating capacity shortage/comfort
problem (in case of frequent domestic hot water operation,
frequent and long space heating interruption will happen)
when selecting [6‑0D]=0 ([A.4.1] Domestic hot water
Type=Reheat only).
INFORMATION
If a third‑party tank is present in the system, and heat
pump operation is...
...required and allowed, set [E‑07] to "0".
...NOT allowed, set [E‑07] to "6". If [E‑07]=6, the unit limits
the maximum setpoint to 60°C.
If a third‑party tank is present in the system ([E‑07]=6), it is
recommended to set [6‑0D] to "0" (i.e. Reheat only).
