4.4.1 Optional: Connection of an external heat
For support or as an alternative for heating by the heat pump you
can connect external heat generators (e.g. Solar, gas or oil boiler)
to the DAIKIN EKHHP.
The heat supplied by the external heat generator must be added
to the unpressurised storage tank water in the DAIKIN EKHHP
hot water storage tank.
● Carry out hydraulic connection in accordance with one of the
two following possibilities:
a) EKHHP(3/5)00AA2V3:
