An ON temperature > 45°C makes sure that only
the electrical Booster Heater (BOH) is used and not
the heat pump. This increases the usage duration of
the refrigerant compressor.
In the operating modes "ECO" and "Automatic" the
hot water heating mode only starts when the
measured hot water temperature falls below 45°C.

– [6-02] GCO (BOH): stipulates when the Booster Heater
(BOH) can be started after the heat pump has been switched
on. This setting is only effective if simultaneous operation of
the Booster Heaters (BOH) and the heat pump is permitted
([4-03] is not set to 0).
– [6-03] Priority of "High Output" operating mode: stipulates the
priority if the operating modes "Low Noise" and "High Output"
are active at the same time.

Operation, Parameters
[7-00] - Low tariff mains connection (HT/LT) / Smart
Grid connection (SG)
These parameters facilitate the configuration of the DAIKIN Hot
water heat pump with an existing low tariff mains connection and
Smart Grid connection.
As soon as the function is activated by the parameter [7-00] > 0,
the operation of the DAIKIN Hot water heat pump is changed, de-
pending on the switch position of the connected potential-free ex-
ternal switching contact.
The following setting options are available:
– [7-00]: Stipulation as to whether the heat pump is connected
to a low tariff mains connection / Smart Grid connection.
– 0 = Normal mains connection (default setting).
– 1 = Evaluation low tariff mains connection.
– 2 = Evaluation low tariff mains connection.
– 3 = Evaluation low tariff mains connection and Smart Grid
connection.

[7-01] Switch hysteresis Booster Heater (BOH)
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 (BOH) is switched in
for hot water generation (see fig. 5-6).
The following setting options are available:
– [7-01] Switching hysteresis Booster Heater (BOH) when hot
water set temperature is above the maximum possible hot
water temperature in exclusively heat pump mode.
