Daikin hybrid for multi heat pump – heat pump module
4P471756-1C – 2017.10
#
Code
Description
N/A
[7‑03]
Compares the primary energy use of the
heat pump with that of the boiler.
Range: 0~6, step: 0.1 (default: 2.5)
INFORMATION
▪ The primary energy factor can always be set, but is
only used in case the savings mode is set to
Ecological.
▪ To set electricity price values, do NOT use overview
settings. Set them in the menu structure instead
([7.4.5.1], [7.4.5.2], and [7.4.5.3]). For more information
on how to set the energy prices, see the operation
manual and the user reference guide.

INFORMATION
In order to optimise comfort as well as running costs, it is
recommended to choose weather-dependent setpoint
operation. Set the settings carefully; they have significant
influence on heat pump as well as boiler operation. Too
high leaving water temperature can result in constant boiler
operation.

INFORMATION
Changing these settings can result in discomfort. Refer to

Leaving water temperature: Modulation
#
Code
Description
[A.3.1.1.5]
[8‑05]
Leaving water temperature modulation:
▪ 0 (No): Disabled
▪ 1 (Yes): Enabled. The leaving water
temperature is calculated according
to the difference between desired
and actual room temperature. This
allows
better
matching
of
the
heat
pump
capacity
to
actual
required capacity and results in less
start/stop cycles of the heat pump
and more economic operation.
N/A
[8-06]
Leaving water temperature maximum
modulation:
0°C~10°C (default: 5°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.
