5.3 Operating modes

MAXIMUM ENERGY UTILISATION
The most effective energy utilisation is achieved by the
DAIKIN Hot water heat pump at the lowest possible
hot water temperatures.
At temperatures in excess of 50°C, the effectiveness
(COP) of the DAIKIN Hot water heat pump will be
made worse by the heating support provided by the
electrical heater (Booster Heater), depending on the
outdoor temperature.

5.3.1 ECO

In order to increase the efficiency, we try not to use the integrated
electrical Booster Heater (BOH) in this operating mode (simulta-
neous operation of Hot water heat pump and Booster-Heater
(BOH) is not permitted, other than with activated "Low-Noise Op-
eration").
In addition, most individual settings can be made in order to guar-
antee convenient and efficient operation. The settings are carried
out using the parameters, as described in chapter 5.6.
If the installation is switched on, it regulates the hot water gener-
ation fully-automatically based on the set tipulations in the con-
troller.

● Use the and
water temperature.
The hot water set temperature should be selected so
that, in combination with the setting for the hysteresis
(parameter [6-00]), the buffer storage of the DAIKIN
EKHHP is not cooled excessively by the hot water
generation.
The hot water generation can be affected by additional functions:
– Low-noise operation
– Switching times programming
– Automatic defrosting function
– Thermal disinfection (Legionella protection)
– HT/NT Function
– SmartGrid Function
If the user enters a value manually, this setting remains active
until the user changes it or until set special functions affect it.
At the end of the special function, we again use the set value.
Setting the switching times for the hot water generation is de-
scribed in chapter 5.4.
If the set temperature value for hot water generation is not
achieved by the heat pump external unit, the controller switches
over to the integrated Booster Heater (BOH).
The Booster Heater (BOH) is only switched on if the hot water
temperature has been set above the maximum temperature
value achievable by the heat pump (T
measured by the temperature sensor has reached the temper-
ature (T ).

5.3.2 Automatic

This operating mode is identical to the operating mode "ECO",
but the integrated electric Booster Heater (BOH) is automatically
switched on to aid heating and other settings are carried out au-
tomatically to guarantee convenient operation.

The current target temperature for hot water is displayed
for 5 s on the display of the controller.

the required hot water temperature.
Higher power costs can be generated than with other
operating modes when using this operating mode.
When you press the key again, the operating mode
"Automatic" is switched off and the icon

5.3.3 Low Noise

Low noise mode means that the exterior heat pump unit is oper-
ating at reduced output. This reduces the operating noise caused
by the exterior heat pump unit.
The operating mode "Low noise operation" reduces the
output in DHW heating operation with the result that it
may no longer be possible to reach the preset target
temperatures.
● Press the key.

5.3.4 High Output

It is heated to the set hot water temperature using a heat pump
and integrated electrical Booster Heater (BOH).
The operating mode "High Output" can be activated if larger hot
water draw-off volumes are required for a short period.
● Press the key.

The output support is automatically deactivated again once the
specified target temperature for hot water is reached.

5.4 Setting the timer programme

The DAIKIN EKHHP can be controlled according to manual set-
tings or according to a freely-programmable timer programme.
A timer programme is not included at the factory.
The user can programme up to 5 switching points for each day to
control the hot water generation and the operating mode (normal,
low noise).
The timer programme is switched on and off using the
Saved time switching points can be changed or deleted at any
time. To have a better overview, we recommend making a record
of the programmed switching times and keeping this in a safe
place.
The user can carry out manual setting changes even if the timer
programme is switched on. The controller always only works ac-
cording to the most recent user parameters set until new param-
eters are set. In this way, manually executed settings are can-
celled by the timer programme at the next active switch time.
