Smart Grid - SG)

Once the function is activated by the parameter [7-00] = 3 (see
Section 7.5.2), the heat pump is changed to Stand-By, Normal or
an operating mode with higher temperatures, depending on the
signal from the energy supply company.
To do this, the potential-free switchinf contacts HT/NT + SG of
the EVU receiver need to be connected to the terminal rail con-
nections (GND+IN1) / (GND+IN2) of the DAIKIN EKHHP (see
Fig. 4-12).
As soon as the function Smart Grid is active, the HT/NT function
is deactivated automatically. Depending on the value of the pa-
rameter [7-00], the heat pump is operated differently (see
Tab. 7-3).
4.8.4 Optional: Connection of an external heat
generator
When using an external heat generator, this can be connected
using a potential-free switching contact (HT/NT) on the DAIKIN
EKHHP.
If the potential-free switching contact is closed by an external
heat generator, the DAIKIN EKHHP reduces its own heat gener-
ation in order to favour the external heat generator (settings see
Section 7.5.2).
