The following setting options are available:
– [7-00]: Stipulation as to whether the heat pump is connected
to a high/low tariff mains connection / Smart Grid connection.
– 0 = Normal mains connection (default setting).
– 1 = Evaluation HT/NT mains connection.
– 2 = Evaluation HT/NT mains connection.
– 3 = Evaluation HT/NT mains connection and Smart Grid
connection.

Tab. 7-3 Configuration table parameter [7-00]
Explanations of behaviour of the heat pump as per Tab. 7-3:
Normal operating mode: Heat pump operating works in the set
operating mode, as described in Section 7.3.
Reduced mode: Heat pump works only in heat retention function
with a fixed target value of 40 °C. The Booster-Heater (BSH) is
never added in parallel. This function is also carried out if the pa-
rameter [0-04] = 0 is set.
Switch-on recommendation: Heat pump works with increased
set value and reduced switch-on hysteresis. The Booster-Heater
(BSH) is added in after 60 minutes at the earliest in accordance
with the settings of parameter [4-03].
Switch-on command: The heat pump works in high-perfor-
mance mode with a greatly increased set value. The Booster-
Heater (BSH) is always added in immediately.
[7-01] - Switching hysteresis Booster-Heater (BSH)
If the hot water set temperature is set to a value which is above
the maximum hot water temperature achieved in exclusively heat
pump mode, the electrical Booster-Heater (BSH) is switched on
for hot water generation (see Fig. 7-6).

[7-02] - Emergency operation
The parameter [7-02] is set to "0" in the factory. If there is a fault
in the heat pump external unit, the parameter [7-02] =1 can be
set. In addition, the unit must be set to the operating mode "Au-
tomatic".
This is used for the hot water generation if the error is detected
just by the electric Booster-Heater (BSH).
Inform the DAIKIN Service Expert.
Please use this function only in the event of a fault and
you should always reset as soon as the repairs have
been carried out, since otherwise elevated costs will be in-
curred.
The electric Booster-Heater (BSH) is activated if a fault in the
heat pump external unit has occurred and has been detected for
longer than 1 hour.
[7-04] - Minimum ambient temperature
This parameter defines the minimum external temperature at
which the heat pump is still operated.
[E] - Display unit information
These parameters allow the display of various different unit infor-
mation in the heat pump inside unit DAIKIN EKHHP.
No settings can be made for this parameter.
