50 - Display Service technician required
This icon shows that the system must be checked. Get in touch
with your heating specialist or nearest DAIKIN contractual
partner.
51 - Display Parameter code or Fault code

52 - Keys Setting hot water temperature
These keys are used to adjust the set temperature for hot water
generation.
53 - Key operating mode "Automatic"
This key activates and deactivates the automatic mode. this op-
erating mode, the integrated Booster-Heater (BSH) in the storage
tank of the DAIKIN EKHHP can be added in for the heating up
process if required.
54- Key Programming
This multifunction key is used to program the switching times.
55 - Key operating mode "High Output"
This key activates and deactivates the accelerated heating
mode. Heating up is by heat pump and integrated Booster-Heater
(BSH).
56 - Key activation/deactivation of timer programme
The main function of this multifunction key is to activate/deac-
tivate the timer programme. The key is also used to programme
the parameters.
57 - Key operating mode "Low Noise"
This key activates and deactivates the low noise mode. In this op-
erating mode the output of the system is reduced so that the op-
erating noise of the external heat pump unit is reduced.
58- Key Time setting
These keys have several functions such as:
– Setting the time.
– Switching between the display of outside temperature and the
storage tank temperature (see Section 7.2.3).
– Setting the switching times for the timer programme.
59 - Key error code / parameter setting
This key has several functions:
– Extended key push (>5 sec.): Setting the parameters
– Brief key push: Display of last fault code

7.2.4 Defrost

At low outdoor temperatures and corresponding humidity values,
the external heat pump unit may ice up. This icing impairs effi-
cient operation. The system detects this condition automatically
and starts the melting operation
During the melting operation the heat pump internal unit
(EKHHP) has heat extracted from it and the Booster-Heater
(BSH) is added in, if required.
After 8 minutes at most, the system returns to normal mode.

MAXIMUM ENERGY UTILISATION
The most effective energy utilisation is achieved by the
DAIKIN at the lowest possible hot water temperatures.
At temperatures in excess of 50 °C, the effectiveness (COP) of
the DAIKIN hot water heat pump could be made worse by the
support of the electric immersion heater (Booster-Heater), de-
pending on the outdoor temperature.
